Introduction: Why Exercise Matters More on TRT
Are you getting the most out of your testosterone replacement therapy? For many men on TRT, the answer is no—and the missing link is often a properly designed exercise program. While testosterone therapy creates the optimal hormonal environment for muscle growth and fat loss, it takes the right combination of resistance training and cardiovascular exercise to unlock your body's full potential.Research consistently demonstrates that testosterone combined with resistance training produces significantly greater gains in muscle mass and strength than either intervention alone.
A 2024 randomized clinical trial published in The Aging Male found that men over 70 receiving both testosterone therapy and progressive resistance training experienced meaningful improvements in physical performance and reduced fatigue compared to controls—benefits that persisted at one-year follow-up.
This comprehensive guide will provide you with evidence-based strategies for optimizing your exercise program while on TRT. Whether you're new to the gym or a seasoned lifter looking to maximize your results, you'll learn the specific training protocols, exercise selection, and recovery strategies that work synergistically with hormone optimization.
How Exercise Interacts with Testosterone Replacement Therapy
There is ongoing discussion in the scientific literature about the relationship between exercise and testosterone levels. Conflicting results across studies can be explained by differences in exercise intensity, duration, and the individual characteristics of participants such as age and baseline fitness level.Relatively short-duration intense activity may lead to transient increases in testosterone concentrations, while prolonged exercise (overtraining) may actually suppress testosterone levels for several days. Athletes who train intensively may experience reductions in testosterone levels, though typically not below the normal clinical range.
The Synergy Between TRT and Resistance Training
For men on TRT, exercise takes on additional significance. Testosterone is one of the most potent naturally occurring anabolic hormones, promoting muscle growth through two key mechanisms: stimulating protein synthesis (anabolic effect) and inhibiting protein degradation (anti-catabolic effect). Combined, these effects account for testosterone's promotion of muscle hypertrophy.Research published in the Journal of Applied Physiology demonstrated that 16 weeks of testosterone replacement therapy combined with resistance training resulted in a robust 27.5% increase in muscle fiber cross-sectional area, compared to a 9% decrease in the TRT-only group. This finding underscores a critical point: TRT restores the hormonal environment for muscle growth, but you still need the stimulus of resistance training to trigger actual hypertrophy.
Proven Benefits of Exercise for Men on TRT
When done correctly, exercise can provide the following evidence-based benefits that extend well beyond aesthetics:• Improved muscle function and strength — Enhanced physical capacity for daily activities and athletic performance
• Reduced trunk (belly) fat — Combined aerobic and resistance training shows the greatest reductions in waist-to-hip ratio, particularly in men
• Increased muscle mass — Meta-analyses show average gains of 2–5 kg lean mass over 6–12 months when combining TRT with structured resistance training
• Decreased LDL cholesterol — Regular exercise improves lipid profiles independent of weight loss
• Decreased triglycerides — Muscle hypertrophy induced by resistance training may decrease triglycerides in those with elevated levels
• Improved mood and decreased stress — Exercise enhances neurotransmitter function and reduces cortisol
• Increased bone density — Weight-bearing and resistance exercises stimulate osteoblast activity
• Improved aerobic function and lung capacity — Cardiovascular exercise enhances oxygen utilization efficiency
Getting Started: Preparation and Safety
Before beginning any exercise program, consider some important preparatory steps. Have your blood pressure, heart rate, weight, body dimensions, fasting cholesterol, triglycerides, and blood sugar measured. Your healthcare provider should advise whether you are capable of exercising without health risks.If you feel too tired and weak to begin intensive training, start by walking every day to your best ability. Walking can increase your energy levels so you can eventually start a more intensive exercise program. Consider using a pedometer or smartphone app to measure your daily steps; aim to reach 10,000 steps per day, as this level has been associated with good cardiovascular health and fat loss.
Understanding the Two Types of Exercise
There are two fundamental types of exercise: resistance (weight) training and cardiovascular (aerobic) exercise. Each serves distinct purposes:Resistance training uses weights or body resistance to induce muscle growth. This is the primary driver of muscle hypertrophy and strength gains. Research shows that resistance training is essential for men on TRT who want to maximize the anabolic benefits of hormone optimization.
Cardiovascular exercise improves your body's aerobic capacity—the way it uses oxygen. It also increases your metabolism, helping you burn fat, lower bad cholesterol and triglycerides, and improve blood sugar control. A 2024 meta-analysis in JAMA Network Open found that at least 150 minutes per week of moderate-intensity aerobic exercise is associated with clinically important reductions in waist circumference and body fat.
The Five Foundational Compound Exercises
Compound exercises are multi-joint movements that engage multiple muscle groups simultaneously. These movements form the foundation of any effective strength training program because they allow you to lift heavier weights and trigger greater hormonal responses, creating a conducive environment for muscle growth.Research published in the Journal of Strength & Conditioning Research confirms that compound lifts activate three key components for building muscle: mechanical tension, muscle damage, and metabolic stress. The following five exercises should form the core of your training program:
1. Squats
The squat is perhaps the most important compound movement, targeting the quadriceps, glutes, hamstrings, and core. Keep your back arched throughout the movement, face forward and up, and position your legs slightly wider than shoulder-width apart. Descend as if sitting into a chair, then drive up through your heels.Proper depth is essential—your thighs should reach at least parallel to the floor. Shallow squats don't fully engage the glutes and hamstrings, leading to incomplete muscle recruitment. Research shows squat strength is strongly linked to sprinting speed and jumping ability.
2. Deadlifts
Deadlifts build and strengthen the entire posterior chain: hamstrings, glutes, lower back, and upper back. Position your legs shoulder-width or less apart, with hands inside your knees. Arch your back as you lift to ensure the lower back muscles are properly engaged.The deadlift produces substantial increases in anabolic hormone release and creates neurological strength adaptations that carry over to other lifts. Maintain a neutral spine throughout—a rounded back during deadlifts is a common mistake that can lead to serious injury.
3. Bench Press
The bench press is the classic upper body compound movement, targeting the chest (pectoralis major), shoulders (anterior deltoids), and triceps. Ensure your back is pressed firmly against the bench, lower the bar to touch your chest, and press upward until your arms are fully extended.Keep your elbows at approximately 45 degrees to your body, not flared out to 90 degrees. Research shows push-ups can be equally effective for building muscle when performed with proper intensity, making them an excellent alternative when equipment isn't available.
4. Overhead Press (Military Press)
The overhead press builds shoulder mass and strength while engaging the core for stability. Sit on a bench with your forearms perpendicular to the bar, then press directly overhead until your arms are fully extended.This exercise ranks with equal importance to the squat, deadlift, and bench press for building overall strength. The military press creates significant functional strength that translates to everyday activities.
5. Barbell Rows or Pull-ups
These horizontal and vertical pulling movements are essential for balanced development. The bent-over row and bench press are direct opposites—together, they create the balance needed for strength and good posture.Pull-ups are the ultimate relative strength test, hitting your back, shoulders, and biceps. If you can't perform full pull-ups initially, work on a progression using resistance bands or assisted pull-up machines.

Practical Training Recommendations
Resistance Training Protocol
Train with weights and machines three times per week for no more than one hour. Starting with machines is the safest approach until you become familiar with movement patterns. As you feel more confident and strong, incorporate free weight exercises, ideally with a workout partner for safety.A basic framework for each session:
• Exercise one body part per week with three exercises per body part
• Perform one light warm-up set followed by two heavier sets
• Target 8–10 repetitions to momentary muscle failure
• Keep rest periods to 20–30 seconds between sets
• Progressively increase weights as you get stronger
Cardiovascular Exercise Protocol
Perform low-impact aerobic exercise for 20–40 minutes, three to four times per week. Effective options include:• Brisk walking
• Stationary or outdoor cycling
• Stair stepping
• Elliptical trainer
• Swimming or water aerobics
Switching between different exercises can help maintain interest and motivation. Be cautious about excessive aerobic exercise if you are losing weight involuntarily, feeling overly tired, or recovering from illness.
Sample Weekly Training Schedule
Day | Focus | Duration |
| Monday | Resistance: Chest, Shoulders, Triceps | 45–60 minutes |
Tuesday | Cardiovascular: Moderate intensity | 30–40 minutes |
Wednesday | Resistance: Back, Biceps | 45–60 minutes |
Thursday | Cardiovascular: Moderate intensity | 30–40 minutes |
Friday | Resistance: Legs (Squats, Deadlifts) | 45–60 minutes |
Saturday | Active Recovery: Walking, light stretching | 20–30 minutes |
Sunday | Rest Day | Complete rest |
Critical Form and Technique Guidelines
Proper form is the foundation of effective, injury-free training. The following principles apply to every exercise:• Learn how to do each exercise correctly. Concentrate on using strict form to get the most out of each exercise and prevent injuries.
• Warm up your muscles before targeting them with challenging weights using a light, high-repetition warm-up set.
• Don't use momentum. Cheating by swinging or bouncing takes work away from the targeted muscles. Use a deliberate, controlled speed.
• Use a full range of motion. Feel the muscle stretch at the bottom and achieve peak contraction at the top. Don't rush through repetitions.
• Focus on the mind-muscle connection. Keep your attention on the muscles working, not on random thoughts or people around you.
• Select appropriate weights. If you can easily do more than 12 repetitions, increase the weight. You should barely be able to complete the final rep with proper form.
Avoiding Overtraining: The Critical Factor Most People Ignore
Working out for more than an hour can cause overtraining, which can actually destroy your muscles and decrease your strength. Overtraining syndrome (OTS) is probably the factor most ignored by exercise enthusiasts, yet it's one of the most important considerations for men on TRT.Prolonged excessive exercise may lead to suppression of testosterone levels, potentially lasting several days. Research published in 2024 in Progress in Cardiovascular Diseases describes how overtraining results from excessive physical activity without adequate recovery, leading to alterations in the hypothalamic-pituitary-adrenal axis and testosterone-to-cortisol ratio imbalances.
The Paradox of Training
To build muscle, the body must receive a stimulus—a reason to grow bigger. The body only does what it needs to do. If challenged to move weights, it responds by growing. However, overdoing exercise stresses the body and initiates the process of breaking down muscle mass as the body burns its own muscles for fuel.It seems paradoxical that you could work out less and grow more, but this is often the case. Any exercise beyond the exact amount necessary to induce optimal muscle growth is called overtraining. The threshold varies from person to person—you need to listen to your body.
Warning Signs of Overtraining
• Persistent fatigue that doesn't improve with rest• Decreased performance despite continued training
• Increased susceptibility to colds and infections
• Mood changes: irritability, depression, loss of motivation
• Disturbed sleep patterns
• Unexpected weight changes
• Elevated resting heart rate
Nutrition and Recovery: Maximizing Your Results
Hydration
Drink at least eight glasses of water daily to stay properly hydrated. Dehydration can significantly impair workout performance and recovery. Avoid sugary drinks, as they cause fatigue after an initial energy burst. Some people find benefit from green tea or creatine supplements in water before training to enhance workout energy.Pre-Workout Nutrition
Do not work out immediately after eating a regular meal—wait at least two hours. If you need a pre-workout snack, have some fruit and a slice of toast with peanut butter one hour or more before training. Avoid protein shakes before exercise, as digestion will divert blood flow from working muscles and decrease energy levels.Post-Workout Nutrition: The Anabolic Window Revisited
The concept of a narrow "anabolic window" has been extensively studied and largely debunked. A 2024 meta-analysis in Frontiers in Nutrition found that total daily protein intake appears to be the primary factor in facilitating muscle growth, rather than precise timing around exercise.That said, consuming protein within 30–60 minutes after training remains a practical approach. A post-workout meal should contain:
• Protein: Whey protein, lean meat, eggs, or plant-based alternatives (target 1.6–2.2 g/kg bodyweight daily)
• Healthy fats: Olive oil, flaxseed oil, or omega-3 sources
• Complex carbohydrates: Fruits, whole grains, vegetables
Beneficial Supplements
Consider these evidence-supported supplements:• Creatine monohydrate: Extensively researched for improving strength and power output
• Whey protein: Convenient source of high-quality protein with rapid absorption
• Glutamine: May support immune function during intense training periods
• Omega-3 fatty acids: Anti-inflammatory benefits supporting recovery
Machines vs. Free Weights: What Works Best for TRT Patients
This is one of the most common questions in the ExcelMale community. Both training modalities have distinct advantages:Free Weights
Free weights are generally considered superior for overall strength and muscle gains because they force engagement of stabilizer muscles. Multi-joint movements create the best overall strength and mass gains. However, free weights are also the number one source of gym injuries. They should be used by people who know proper form and maintain strict technique.Machines and Cables
Machines provide a safer alternative, especially valuable for men who have had previous injuries or are returning to training after time off. As Nelson Vergel notes from personal experience: "I focus on cable and other machines as I grow older. Luckily, I have not injured myself in 30 years."Recommended Approach
For most men on TRT:1. Begin with machines to learn movement patterns safely
2. Gradually incorporate free weights as form improves
3. Use a combination based on your injury history and goals
4. Consider using machines exclusively if you have joint issues or past injuries
Tracking Your Progress: The Workout Log
Keeping a workout log is one of the most valuable habits you can develop. The primary reason to track workouts is to see graphically what you're accomplishing. You'll be able to determine whether you're gaining strength at a reasonable rate and identify patterns that might indicate overtraining.Document your workouts by recording:
• The weight you lift for each exercise
• The number of repetitions completed
• How you felt during the workout
• Any soreness or fatigue issues
When you train the following week, you'll know exactly what you're trying to improve upon. If you find yourself weaker than the previous session despite proper nutrition and rest, you may be overtraining.
Home-Based Exercise Options
If you don't have access to a gym, you can still achieve meaningful results. As long as you're resisting your own body weight, you're doing resistance exercise. Here are three affordable, effective tools:5. Exercise (Medicine) Ball and Elastic Bands: Available at most retail stores for under $20. These allow for a full range of exercises targeting every major muscle group.
6. Door Frame Pull-Up Bar: No installation required for many models. Pull-ups are one of the most effective compound exercises for upper body development.
7. Pedometer or Fitness Tracker: Wear it from waking to bedtime to ensure you're reaching close to 10,000 steps daily for optimal cardiovascular health.
Basic bodyweight exercises like push-ups on the floor and squats holding household items (books, water bottles) can be surprisingly effective when performed with proper intensity and progressive overload.
Special Considerations for Men on TRT
Realistic Expectations
Based on meta-analyses from 2018–2023, men on TRT with structured training can expect:• Average lean mass gain: 2–5 kg over 6–12 months
• Time to visible changes: Approximately 3 months with consistent training
• Subtle changes: Begin appearing at 4–8 weeks
Age Considerations
For older men, using lighter weights with higher repetitions may be preferable to prevent injury. Research shows that muscle hypertrophy can be achieved with both heavy and moderate loads on a work-matched basis. In fact, heavy load protocols may not be sustainable for older trainees due to joint stress and recovery demands.The 2024 study in The Aging Male specifically demonstrated that for men over 70 with low testosterone and mobility problems, the combination of testosterone therapy with progressive resistance training produced the greatest improvements in physical performance—validating that it's never too late to benefit from structured exercise.
Safety First: Injury Prevention
Remember: if something hurts during an exercise, stop immediately. Ask for help to identify the problem—it may be improper form. If you injure yourself, you will hinder your progress because you won't want to work out. Learn proper form from the beginning.Additional safety guidelines:
• Do not exercise if you feel you are coming down with a cold or illness
• Always warm up before training and stretch afterward
• Have a spotter when lifting heavy weights
• Progress gradually rather than attempting dramatic weight increases
• Get adequate sleep (7–9 hours) for optimal recovery
