Are You Actually Fight Ready? What Most Fighters Get Wrong About Conditioning

Written by Evelyn Calado, MKin, CSCS, RKin

You think you’re in shape.
Until round two.

Everything feels sharp early. Your hands are fast. Your feet are light. You’re seeing openings.

Then your output drops. Your shoulders start to burn. Your breathing spikes. Now you are surviving instead of fighting.

This isn’t a lack of toughness.
It’s a conditioning problem.

More specifically, it is a fight conditioning problem that most fighters never actually address.

The Real Problem Isn’t Effort

Most fighters do not lack work ethic.

They train hard. They push themselves. They leave the gym exhausted.

The problem is they are training the wrong things at the wrong time.

A lot of fighters live in what we call the gray zone. Sessions that are not easy enough to build a real aerobic base. Not intense enough to develop true fight specific power. Just hard enough to feel tired.

And feeling tired gets mistaken for getting better.

But fatigue is not a performance metric.

Fighting is not about how tired you can get. It is about how long you can produce, recover, and repeat high intensity efforts.

Why Fighters Misjudge Their Conditioning

Gym Conditioning Is Not Fight Conditioning

You can hit pads hard, push through circuits, and still gas out in a fight or sparring.

Because fighting is not continuous effort. It is intermittent.

Short explosive bursts.
Brief recovery periods.
Repeated over multiple rounds.

All energy systems are working together, not just general effort.

If your training does not reflect that structure, your conditioning will not transfer.

No Objective Testing

Most fighters judge conditioning based on how tired they feel or how hard a session was.

That is guesswork.

Without testing, you do not know if your output is dropping round to round, if your recovery is improving, or where your actual limitation is.

Without testing, you are guessing.

Over Reliance on Fatigue

A hard session feels productive.

But you can get better at tolerating fatigue without improving the systems that actually drive performance.

That is why some fighters look great in training but fall apart when the pace of a real fight hits.

What Actually Matters for Fight Conditioning

To perform at a high level, you need a system, not just effort.

Aerobic Base

This is your foundation.

A well developed aerobic system helps you recover between exchanges, maintain output, and sustain effort across rounds.

Repeat Power

Explosive combinations rely on your highest power output.

The key is not just producing power once. It is being able to repeat it with limited recovery.

Glycolytic Capacity

Longer exchanges and flurries are where most fighters begin to break down.

If this system is not developed, output drops and technique starts to fade.

Recovery Between Efforts

This is one of the biggest separators.

Fighters who recover faster between bursts can maintain pace and stay effective deeper into rounds.

Efficiency Under Fatigue

At a high level, conditioning is also about efficiency.

Can you stay relaxed when tired?
Can you maintain technique?
Can you make good decisions under pressure?

That is what real fight readiness looks like.

Why Testing Matters

Most fighters know they get tired.

Very few know why.

Testing does not give you every answer, but it gives you a clearer picture of what is happening. Especially when it comes to fight conditioning and repeat effort performance.

It can help show how your heart rate responds to work, how your output changes over time, and how well you repeat high intensity efforts.

It gives direction to your training instead of relying on guesswork.

Where We Come In

This is part of what we look at in our performance testing at Avos Strength.

We use simple, practical tests to get a snapshot of how your conditioning is functioning and how it compares to other athletes.

It is not about labeling you as fit or unfit.

If you feel like you are doing everything right in training but still fading in sparring or competition, you are not alone.

Most fighters are working hard.

Very few are training with clarity.

How to Train Like a Pro Without Overtraining: 3 Conditioning Mistakes Every Fighter Makes

Written by Evelyn Calado, MKin, CSCS, RKin

“You’re in shape… until you aren’t.”

Every boxer knows the feeling. You think you’re in shape, you’re sparring well, and then by Round 2 your legs feel like concrete. The problem isn’t effort. It’s the wrong kind of conditioning.

In combat sports, the difference between being fit and being fight ready is small but critical. Fighters often equate exhaustion with improvement. But fatigue is not the goal. The goal is to develop a system that lets you recover, repeat, and stay sharp under stress.

True conditioning teaches your body how to sustain power and recover faster between bursts. It builds the capacity to deliver the same output over and over without falling apart technically.

Mistake #1: Living in the “No-Adaptation Zone”

Most fighters train at one speed all the time. The intensity is too high to truly build aerobic qualities, yet not high enough to improve anaerobic power. This middle zone feels hard but does not create meaningful adaptation.

Training in this gray area leaves you constantly tired without improving the key factors that drive endurance. The aerobic system is the foundation for every other energy system. It is what allows you to recover between flurries, maintain composure, and control your pace.

When the bulk of training sits around 80 to 85 percent of maximum heart rate, the heart and muscles are working, but they are not being pushed to develop either side of the spectrum.

Fix:
Include one dedicated aerobic session each week. Keep the effort at a comfortable but steady pace where you can still breathe through your nose.

• 25 to 30 minutes at 65 to 75 percent of maximum heart rate, or RPE 4 to 5.

• Use light jogging, a spin bike, or shadowboxing flow work.

These lower-intensity sessions build the foundation that makes every other type of conditioning more effective later in camp.

Mistake #2: Mistaking Fatigue for Progress

If every session leaves you completely drained, you are not building capacity, you are burning it.

Fatigue by itself does not equal progress. When you constantly push to exhaustion, your coordination drops, timing slows, and recovery between rounds suffers.

Conditioning should improve the ability to produce high effort repeatedly, not the ability to survive pain. The aim is quality effort, not constant exhaustion.

Fighters often overload glycolytic, or medium-duration, efforts. They push too hard for too long and never develop the shorter, high-power system or the longer aerobic system that supports it. The result is a strong first thirty seconds and then a quick drop-off in speed and output.

Fix:
Introduce short, high-quality power intervals that target your explosive energy system.

• Perform 8 to 10 seconds of all-out work such as a bike sprint, heavy bag flurry, or sled push.

• Rest for 80 to 100 seconds at an easy pace before repeating.

• Complete 6 to 8 total efforts.

These efforts improve maximal power and nervous system efficiency while allowing full recovery between reps.

Mistake #3: Ignoring the Aerobic Engine

The aerobic system is what keeps fighters explosive through multiple rounds. It is also what allows the body to recover between rounds and between training sessions.

Aerobic training does not make a fighter slow. It develops the internal engine that supplies energy to every burst and every exchange. A well-developed aerobic system improves the ability to replenish ATP, clear hydrogen ions, and use lactate as a fuel source during sustained work.

The common idea that fatigue is caused by lactic acid buildup is outdated. Lactic acid does not actually accumulate in the muscles. Instead, it separates into lactate and hydrogen ions, and the resulting increase in acidity contributes to fatigue. Aerobic training improves the body’s ability to manage that acidity and maintain performance over time.

Fix:
Use structured aerobic capacity intervals once or twice a week.

• Work for 2 to 3 minutes at 80 to 90 percent of maximum heart rate or RPE 6 to 7.

• Recover actively for 2 to 3 minutes until your heart rate drops below 130 beats per minute.

• Repeat 4 to 6 rounds.

This type of interval work develops both delivery and utilization of oxygen, helping you stay relaxed and efficient even at higher outputs.

Why Smart Conditioning Wins Fights

The best-conditioned fighters are not always the ones who look the fittest in training. They are the ones who can stay calm, explosive, and efficient no matter how chaotic the fight becomes.

That calmness is a physiological skill. It comes from balancing the aerobic system that drives recovery, the anaerobic system that fuels sustained power, and the alactic system that supports short, explosive actions.

Smart conditioning develops all three systems in the right sequence and with the right intent. Build the base first, layer power on top, and taper the total load before competition.

Train Systems, Not Just Willpower

The difference between being in shape and being ready to fight is not about effort, it is about precision.

Conditioning should make you faster, more efficient, and more durable. It should leave you confident that your body can keep up with your skill. Hard work matters, but only when it builds something specific.

“Hard work is only as good as what it builds.”
— Joel Jamieson

Take the Guesswork Out of Your Conditioning

Knowing what to train is only half the battle. Knowing when and how to train each energy system is what separates a well-conditioned fighter from a tired one. A structured plan designed around your schedule, fight calendar, and current fitness level turns theory into progress.

Why You Should Focus on Building an Aerobic Base Before High-Intensity Training

Written by Evelyn Calado, MKin, CSCS, RKin

If you’re looking to improve your endurance and overall fitness, you might think that going all out with high-intensity workouts is the fastest way to get there. However, when it comes to long-term progress—especially for those training for demanding physical tests like the firefighter physical exam—building a strong aerobic base first is crucial.

What Is an Aerobic Base?

Your aerobic base refers to the foundation of your cardiovascular system’s ability to efficiently use oxygen to generate energy. This system primarily relies on oxidative phosphorylation, a process that allows your body to sustain activity over long durations with minimal fatigue. Training at the right intensities helps improve mitochondrial density, capillary growth, and fat oxidation—key factors in enhancing endurance performance.

Why High-Intensity Training Can Hinder Aerobic Development

Many people assume that intense training leads to faster results, but high-intensity conditioning can actually interfere with aerobic adaptations. Here’s why:

1. Increased Anaerobic Dependence – When you train at high intensities, your body shifts toward anaerobic energy systems (like glycolysis), which produce energy quickly but generate metabolic byproducts like lactate. While your body can handle short bursts of anaerobic work, it’s not an efficient long-term strategy for endurance development.

2. Recovery Demands and Fatigue – High-intensity sessions place significant stress on your muscles and central nervous system, requiring longer recovery times. If done too frequently, they can lead to excessive fatigue and overuse injuries, ultimately stalling progress.

3. Limited Oxygen Utilization Training – Training at lower intensities allows your body to maximize oxygen delivery and utilization, leading to improvements in aerobic capacity (VO2 max), capillary density, and mitochondrial function. These adaptations are essential for sustained endurance.

4. Interference with Adaptations – High-intensity workouts primarily target fast-twitch muscle fibers, while aerobic base training focuses on slow-twitch fibers, which are more efficient at using oxygen for fuel. Overemphasizing high-intensity work too soon can reduce the effectiveness of these adaptations.

The Right Approach: Base Building First

For the first 8-12 weeks of a structured training program, focusing on low to moderate-intensity conditioning is crucial. This means training in specific heart rate zones (usually 60-75% of max heart rate) to optimize oxygen utilization. The goal is to improve endurance while keeping fatigue and injury risk low.

Once a strong aerobic foundation is built, higher-intensity sessions can be strategically incorporated to enhance performance without compromising recovery or long-term progress.

Key Takeaways

• Building an aerobic base improves endurance, recovery, and efficiency.

• High-intensity training too early can lead to fatigue, increased injury risk, and limited aerobic gains.

• A structured plan prioritizing aerobic development first leads to better long-term performance.

If you’re serious about improving your cardiovascular fitness, whether for general health or a specific goal like passing a physical test, patience and consistency with aerobic base training will set you up for success.

How to Stay Fit While Traveling: Tips and Tricks

Traveling is one of life’s greatest joys—it allows you to explore new places, try new foods, and step out of your daily routine. But for those dedicated to their training, it can feel like every trip is a setback. How do you keep moving forward when your schedule is unpredictable, and access to equipment is limited?

The good news is that staying fit while traveling doesn’t have to be complicated or time-consuming. With a bit of planning and creativity, you can maintain your strength, mobility, and overall fitness no matter where you go.

Here are some practical tips and strategies that have worked for me and my clients over the years:

1. Plan Ahead

A little preparation goes a long way. Researching gyms, parks, or hotel fitness centers at your destination ensures you’re not caught off guard. When I travel, depending on the type of trip, I adjust my approach. If I’m staying in one location, I always look for hotels with gyms or find a local gym nearby. Knowing your options ahead of time saves you stress and keeps your routine intact.

2. Prioritize Movement Over Perfection

You don’t need a perfect session to make progress. Focusing on staying active—whether it’s a quick mobility session, a bodyweight workout, or a long walk—keeps you consistent without added stress.
Your training sessions don’t have to be long—30 to 45 minutes is plenty. After all, it’s vacation! Sometimes taking a break is exactly what your body needs to recover and come back stronger. If your trip is a week or less, embracing the change of pace can actually enhance your long-term progress.

3. Choose Active Adventures

Traveling offers endless opportunities to stay active while exploring new places. Instead of opting for passive activities like a bus tour, try a walking tour or rent bikes to explore a new city. When planning excursions, choose active options like hiking, snorkeling, or paddleboarding. These activities keep you moving and allow you to experience your destination in a whole new way.

4. Pack Travel-Friendly Equipment

Bringing the right gear can make all the difference. Resistance bands, a jump rope, or sliders are great lightweight options. My favorite, though, is the TRX suspension trainer. It’s portable, versatile, and perfect for targeting your back—one of the hardest areas to train without access to gym equipment.

5. Make Use of Your Surroundings

Hotel rooms, parks, or beaches can double as great workout spaces. Bodyweight exercises like squats, push-ups, planks, and lunges are versatile and effective no matter where you are.
Don’t overlook playgrounds! Monkey bars and other equipment can be great for bodyweight movements like pull-ups or hanging leg raises.

6. Keep It Simple or Get a Plan

Consistency is key when training while traveling. Having a basic workout template—like alternating push, pull, and lower-body movements—ensures you can adapt to your environment.
If you’re unsure how to structure your workouts, consider having your coach design a custom plan. Whether you have access to a full gym, a hotel fitness center, or just your own bodyweight, a tailored program removes the guesswork and keeps you on track.

7. Stay Mindful of Nutrition

Vacations are a time to enjoy yourself, and food is often a big part of the experience. It’s okay to splurge a little here and there—but try to avoid turning every meal into an all-you-can-eat buffet. Overindulging in high-calorie, low-nutrient foods for a week or more can leave you feeling sluggish and lead to significant weight gain.
To strike a balance, prioritize healthier options most of the time. Choose lean proteins, vegetables, and whole grains when you can, and enjoy richer foods in moderation. Pair this with staying active, and you’ll return from your vacation feeling refreshed, not weighed down by your choices.

Why Your Heart Rate Lowers as You Age: Resting and Maximum Heart Rate Explained

As we age, our bodies undergo numerous changes, and one of the most noticeable in terms of physical activity is the way our heart rate behaves. From resting heart rate to maximum heart rate during exercise, understanding these changes can help us maintain optimal health and fitness as we grow older. In this post, we’ll dive into the science of heart rate, the impact of aging, and what peer-reviewed research tells us about these changes.

Resting Heart Rate (RHR) and Aging

Your resting heart rate (RHR) is the number of times your heart beats per minute when you are at rest, such as while sitting quietly. For most adults, a healthy RHR ranges from 60 to 100 beats per minute (bpm), though highly fit individuals may have a lower RHR, often between 40 to 60 bpm.

How RHR Changes with Age:

As you age, your resting heart rate may change slightly due to:

• Reduced SA Node Efficiency: The sinoatrial (SA) node, which acts as the heart’s natural pacemaker, can lose some of its cells over time, leading to a slower baseline heart rate.

• Stiffening of the Heart Muscle: The heart muscle may become less elastic, impacting how efficiently it pumps blood.

Despite these changes, regular physical activity can keep your RHR within a healthy range. Studies have shown that individuals who engage in regular aerobic exercise maintain a lower RHR as they age compared to sedentary individuals.

Why a Lower RHR is Good:

A lower RHR indicates that your heart is more efficient at pumping blood, which is often a marker of good cardiovascular health. For example, a trained endurance athlete’s RHR may be as low as 40 bpm because their heart is capable of pumping more blood with each beat.

Maximum Heart Rate (MHR) and Aging

Your maximum heart rate (MHR) is the highest number of beats per minute your heart can achieve during intense physical activity. It is an important measure for determining exercise intensity zones and decreases predictably with age.

The Formula:

A widely used formula to estimate MHR is: MHR = 220 – age

For example:

• At age 30: Estimated MHR = 190 bpm

• At age 50: Estimated MHR = 170 bpm

• At age 70: Estimated MHR = 150 bpm

Why MHR Decreases:

• Reduced Responsiveness: Aging affects the cardiovascular system’s ability to respond to stress. The heart’s beta-receptors, which mediate responses to adrenaline, become less sensitive over time.

• Efficiency Adjustments: A lower MHR doesn’t necessarily mean your heart is weaker; it’s part of the body’s natural adjustment to aging.

Note on Accuracy:

The most accurate way to determine your maximum heart rate is through testing, such as a graded exercise test under supervision. However, the age-predicted formula works well for most people as a general guideline.

Research Insights on Heart Rate and Aging

Peer-reviewed research provides valuable insights into how heart rate changes across different age groups and fitness levels:

1. Study on RHR Trends: A study published in The American Journal of Cardiology (2017) tracked RHR trends in over 90,000 participants. Researchers found that active individuals maintained lower RHRs throughout life compared to their sedentary counterparts. For instance, fit men and women in their 50s had RHRs averaging 58 bpm, while sedentary individuals of the same age averaged 70 bpm.

2. MHR and Age Study: Research from the Journal of the American College of Cardiology (2014) highlighted that MHR declines approximately 6-10 bpm per decade after the age of 20. This decline is consistent regardless of fitness level but can be slightly mitigated by regular high-intensity interval training (HIIT).

3. Athlete vs. Non-Athlete Comparisons: A study in Sports Medicine (2021) compared heart rate values between endurance athletes and non-athletes. At age 60, endurance athletes’ MHR was about 10 bpm higher than non-athletes, suggesting that maintaining cardiovascular fitness can slow the decline in heart rate.

Practical Implications for Exercise

Understanding your heart rate can help you tailor your exercise regimen as you age:

1. Monitor Your RHR: Use a heart rate monitor or smartwatch to track your resting heart rate over time. Significant changes may indicate overtraining or other health issues.

2. Adjust Intensity Zones: Use your age-predicted MHR to define your exercise intensity zones:

   • Zone 1: 50-60% of MHR (light activity)

   • Zone 2: 60-70% of MHR (moderate effort)

   • Zone 3: 70-85% of MHR (vigorous exercise)

   • Zone 4-5: 85-100% of MHR (high-intensity efforts)

   Alternatively, a more personalized method involves calculating your heart rate reserve (HRR), which uses both your RHR and MHR. The formula is:

   HRR = MHR – RHR

   You can then determine target zones as percentages of your HRR, added back to your RHR. Many experts consider this approach more accurate for setting intensity levels.

3. Incorporate Variety: Engage in aerobic, strength, and flexibility training to maintain heart health and overall fitness. Activities like walking, swimming, strength training, and yoga can support cardiovascular function at any age.

4. Listen to Your Body: While heart rate is a helpful guide, always prioritize how you feel during exercise. Fatigue or difficulty recovering may signal a need to adjust your workout intensity.

Key Takeaways

• Resting Heart Rate: A lower RHR is a marker of good cardiovascular health, achievable through regular exercise.

• Maximum Heart Rate: Naturally declines with age but remains a valuable guide for exercise intensity.

• Heart Rate Reserve: Using both RHR and MHR to calculate HRR can provide more precise training zones.

• Stay Active: Regular physical activity can mitigate some age-related changes and promote lifelong heart health.

By staying informed and proactive, you can use heart rate as a tool to maintain fitness and health at every stage of life. Always consult with a healthcare provider if you’re unsure about your heart rate trends or exercise routine.

Strength Training For Trail Running

Trail running isn't just a sport; it's a captivating journey through rugged terrain, demanding both physical resilience and mental fortitude. As trail running gains popularity among fitness enthusiasts and adventurers, the importance of strength training in preparing for these exhilarating runs cannot be overstated. Beyond just logging miles on the trail, incorporating strength training into your regimen can be the key to unlocking your full potential as a trail runner.

The Unique Demands of Trail Running

Unlike road running, trail running presents a myriad of challenges. Trails are often uneven, with varying inclines, declines, obstacles, and surfaces. The constant changes in terrain demand exceptional balance, stability, and muscular endurance. Moreover, trail runners must navigate steep ascents and descents, requiring significant lower body strength and power to conquer challenging climbs and maintain control during treacherous descents.

Why Strength Training Matters

Strength training serves as the foundation upon which trail runners build strength, power, and efficiency.

At Avos we are a huge fan of the Trap Bar Deadlift - especially for our tall runners

Here are several reasons why strength training is indispensable for trail runners:

1. Injury Prevention: Trail running places immense stress on the body, increasing the risk of overuse injuries and muscular imbalances. Strength training helps mitigate these risks by strengthening muscles, tendons, and ligaments, enhancing joint stability, and correcting imbalances. A well-rounded strength training program can address weak areas, reduce the likelihood of injury, and promote longevity in the sport.

2. Enhanced Performance: Strength training enhances the body's ability to generate power, endure fatigue, and maintain proper form over long distances. Stronger muscles provide the support and propulsion necessary to tackle steep climbs, power through technical terrain, and navigate challenging descents with confidence. By improving strength and efficiency, trail runners can sustain higher speeds, conquer formidable obstacles, and excel in varying distances and difficulties.

3. Improved Running Economy: Running economy, the measure of how efficiently a runner uses oxygen at a given pace, is crucial for endurance athletes. Strength training contributes to improved running economy by enhancing biomechanical efficiency, optimizing muscle recruitment patterns, and reducing excess energy expenditure. As a result, trail runners can cover greater distances with less effort, allowing for faster race times and improved overall performance.

4. Mental Resilience: Trail running is as much a mental challenge as it is a physical one. Strength training cultivates mental resilience by instilling discipline, focus, and determination. Moreover, it allows individuals to have the confidence in their strength and conditioning to not have to worry as much about being injured and super fatigued. Being strong in the weight room and pushing yourself helps teach runners to embrace discomfort, overcome obstacles, and persevere in the face of adversity—essential qualities for success in trail racing.
   

Designing a Strength Training Program:

When writing a strength training program for trail running, it's advisable to include a variety of exercises that target key muscle groups, address weaknesses, and complement running-specific training sessions. Incorporate a diverse mix of bodyweight movements, resistance training, and plyometrics to enhance core stability, lower body strength, balance, and flexibility. Prioritize exercises like squats, lunges, deadlifts, calf raises, planks, and single-leg movements to strengthen muscles used in running and improve stability on uneven terrain. Ensure that your program progressively challenges your muscles while allowing for sufficient recovery to optimize gains in strength, endurance, and performance on the trails.

Conclusion:

In the dynamic world of trail running, strength training serves as an important tool for unlocking peak performance, preventing injuries, and mastering the challenges of rugged terrain. By integrating strength training into your training regimen, you'll not only become a stronger, more resilient runner but also embark on a transformative journey of self-discovery and exploration.
