Hormone Replacement Therapy (HRT) can be life-changing for transgender women, offering emotional and physical alignment. However, it also brings changes to muscle mass and bone density that can be concerning, especially for those who want to maintain strength without significantly bulking up. As a transgender woman who was once a powerlifter with a 1,495-pound gym total and a competitive bodybuilder, I understand the unique challenges that come with transitioning while maintaining muscle integrity.
Why Muscle Maintenance Matters on HRT
When transitioning, it’s natural to worry about losing the muscle you’ve worked hard to build. Estrogen can lead to muscle atrophy over time, which is exacerbated if muscle maintenance is neglected. Additionally, maintaining muscle strength is essential for more than aesthetics; it plays a critical role in preserving bone density.
Estrogen, while crucial for feminization, can lower bone density when compared to testosterone. This means that muscle, which exerts a protective force on bones through resistance training, becomes even more vital in maintaining skeletal health. Simply put, the stronger your muscles, the less likely you are to experience bone loss.
Setting Realistic Goals: Strength, Not Bulk
It’s essential to shift the mindset from ‘bulking up’ to ‘maintaining strength.’ The goal should be to keep muscles functional and resilient rather than increasing size. A common misconception is that lifting heavy weights will always lead to hypertrophy (muscle growth). However, the way you train matters significantly. To maintain muscle without increasing bulk, focus on the following:
- Lower Weight, Higher Reps: Using lighter weights with higher repetitions can maintain muscle endurance and strength without significantly increasing muscle mass.
- Functional Movements: Prioritize compound exercises that utilize multiple muscle groups, promoting balanced strength.
- Core Stability Work: Integrating core exercises like planks and rotational movements will help build a stable base without adding bulk.
- Flexibility and Mobility Training: Keeping muscles supple and joints healthy reduces injury risks and promotes longevity in training.
Optimizing Training for Strength Without Size
To avoid unnecessary hypertrophy while on HRT, consider these training principles:
- Moderate Intensity and Volume: Aim for 3-4 sets of 10-15 reps using a moderate weight. You should feel challenged but not strained.
- Focus on Endurance: Incorporate bodyweight exercises and resistance bands to build endurance rather than just strength.
- Maintain Consistency: Regular workouts prevent muscle atrophy, which is more likely when HRT decreases anabolic (muscle-building) activity.
- Progressive Strength Training: Gradually increasing resistance helps maintain muscle strength without leading to excessive bulk. This method allows your body to adapt slowly, prioritizing endurance over mass.
Varying Your Routine to Stay Engaged and Prevent Plateaus
Sticking with the basics is often the best approach, but that doesn’t mean your workouts have to become monotonous. To keep your muscles adapting and your motivation high, I recommend changing up your exercise selection every 4 to 6 weeks. This isn’t about reinventing your program, it’s simply about refreshing your main lifts or swapping in new movements to challenge your body in slightly different ways.
For example, you might alternate between goblet squats and split squats or switch from push-ups to resistance band chest presses. This small shift not only keeps things interesting, it also helps prevent plateaus by introducing new stimuli for your muscles. Think of it like taking a different route on your daily walk, it’s enough to shake up your routine without throwing out the map entirely.
The Role of Nutrition in Muscle Maintenance
Maintaining muscle while on HRT also involves proper nutrition. Protein remains essential, as it aids in muscle repair and growth. However, since estrogen can change the way your body metabolizes nutrients, it’s important to:
- Include Lean Protein: Chicken, tofu, legumes, and fish can help preserve muscle mass.
- Stay Hydrated: Dehydration can increase muscle soreness and hinder performance.
- Balance Macronutrients: Carbs fuel workouts, while healthy fats support hormonal health.
Finding Your Calorie Maintenance Sweet Spot
Determining your maintenance calorie needs is all about balance, fueling your workouts without unintentionally adding mass. The goal here isn’t rapid weight loss or bulking up, but rather supporting your strength and muscle preservation.
Here’s a straightforward approach:
- Track Your Intake: For one typical week, log everything you eat and drink. Be honest and detailed; yes, that includes coffee creamers and sneaky late-night snacks.
- Monitor Your Weight: Weigh yourself at the start and end of the week, aiming to keep other lifestyle factors steady throughout.
- Calculate Your Average: At week’s end, tally your daily calorie intakes and divide by seven to find your daily average.
If your weight remains stable during that week, you’ve likely found your maintenance calorie level. This baseline gives you the freedom to adjust more precisely, tweaking up or down depending on your goals, energy, and recovery needs while staying true to your strength-first (not size-first) training philosophy.
Why Resistance Training is Essential for Bone Health
As estrogen levels rise, bone density can decrease, increasing the risk of osteoporosis. This is especially relevant for transgender women who previously relied on testosterone’s bone-strengthening effects. Resistance training stimulates osteoblasts (bone-forming cells), promoting bone density. Exercises like squats, deadlifts, and lunges are particularly beneficial when performed with proper form and controlled movements.

Addressing Common Misconceptions
One common fear among trans women is that engaging in strength training will make them appear too masculine. However, estrogen decreases muscle protein synthesis compared to testosterone, meaning that even if you lift weights, significant muscle growth is unlikely without a targeted hypertrophy program.
Instead, focus on the aesthetic benefits of toned muscles and improved posture. Training can help maintain a sleek, athletic physique while supporting long-term health.

Building a Supportive Routine
Here’s a sample weekly routine that balances strength maintenance with endurance and bone health:
- Day 1: Full-Body Strength (Moderate Weight)
- Day 2: Cardio and Core Stability (Low Impact)
- Day 3: Upper Body Endurance (Light Weights, High Reps)
- Day 4: Rest or Light Mobility Work
- Day 5: Lower Body Strength (Moderate Weight)
- Day 6: Yoga or Pilates (Flexibility Focus)
- Day 7: Active Recovery (Walking or Gentle Stretching)
Balancing Cardio: Steady-State vs. HIIT for Best Results
When it comes to cardio, variety isn’t just the spice of life; it’s the secret sauce for lasting progress. Both steady-state cardio, such as brisk walks, consistent cycling, or longer rowing, and high-intensity interval training (HIIT), such as short sprints or circuit bursts, offer distinct benefits that can enhance your fitness, particularly during hormone replacement therapy (HRT).
Steady-state cardio excels at promoting heart and lung health, relieving stress, and supporting overall endurance. It’s gentle on your joints and can be sustained for longer periods, making it accessible no matter your fitness level or experience.
On the flip side, HIIT offers a quick way to boost your metabolism and improve athletic performance. These workouts involve short bursts of intense effort followed by periods of active rest, perfect for busy schedules and ramping up fat burning in less time.
So, do you need to pick just one? Not at all! For optimal results, consider blending both styles throughout your week:
- 1–2 sessions of HIIT per week can ramp up intensity without overtaxing your body or interfering with muscle maintenance.
- On other days, steady-state cardio whether that’s a longer session on the bike or a brisk walk outdoors will keep your recovery on track and support overall wellness.
The key is balancing intensity and recovery so you can maintain strength, safeguard bone health, and enjoy the mental benefits of moving your body.

The Bottom Line
Maintaining muscle without bulking during HRT is not only achievable but beneficial. Focus on functional strength, prioritize bone health, and embrace a training routine that aligns with your goals and identity. Your body is a reflection of your journey, and every effort you make toward health and resilience is a triumph.
Remember, transitioning is about finding your most authentic self, and that includes a fitness routine that empowers you. Keep moving, keep thriving, and above all, keep honoring your strength.
