How to Build Muscle After 50: A Practical Guide

Aging Strong: Building Muscle After 50

Couple sharing exercises.

Aging doesn't mean you have to surrender to muscle loss or weakness. While sarcopenia—the age-related decline in muscle mass—starts after 50, science and strategy can help you fight back and even build new muscle. This guide covers the essentials: resistance training, testosterone replacement therapy (TRT), creatine monohydrate, omega-3 fatty acids, sleep, and diet. Let's break it down.

Resistance Training: The Foundation

Muscle growth starts with stress—mechanical stress, to be precise. Lifting weights or doing bodyweight exercises forces your muscles to adapt and grow. After 50, your recovery might be slower, but consistency is key.

• What to do: Focus on compound lifts like squats, deadlifts, bench presses, and rows. These exercises recruit multiple muscle groups and boost hormone responses. Aim for 3-4 sessions per week.

• How much: Use moderate weights (60-75% of your one-rep max) for 8-12 reps across 2-3 sets per exercise. Progressive overload—gradually increasing weight or reps—is vital for muscle gain.

• Pro tip: Prioritize form over ego. Joint health matters more now, so don’t rush the process.

  
  

Testosterone Replacement Therapy (TRT): A Judicious Boost

Testosterone naturally declines with age, dropping about 1% per year after 30. Low levels sap energy, strength, and muscle-building capacity. TRT can help, but it’s not a magic bullet—it is a tool for those who need it.

• Who it’s for: If you have symptoms of low T (fatigue, low libido, muscle loss) and blood tests confirm levels below 300 ng/dL (ideally above 700 ng/dL), talk to your doctor.

• Benefits: TRT can enhance muscle protein synthesis, increase strength, and improve recovery when paired with training.

• Caution: Don’t jump in blind. Side effects like polycythemia (thickened blood) or prostate issues need monitoring. Work with a specialist to dial in the dose, usually around 100 mg/week via injections or gels.

  
  

Creatine Monohydrate: The Unsung Hero

Creatine isn’t just for young gym enthusiasts. It’s one of the most researched supplements and a game-changer for older adults.

• How it works: Creatine boosts ATP production, giving your muscles more energy for lifts and recovery. It also pulls water into muscle cells, aiding growth.

• Dose: Stick to 3-5 grams daily. There's no need for a loading phase—just mix it into water or a shake.

• Why it matters: Studies show older adults on creatine gain more strength and muscle mass with resistance training than without. It’s cheap, safe, and effective.

  
  

Omega-3 Fatty Acids: Inflammation’s Foe

Chronic inflammation creeps up with age, sabotaging muscle repair. Omega-3s—found in fish oil—counteract this.

• Benefits: They reduce muscle breakdown, improve protein synthesis, and ease joint pain, allowing you to train harder.

• How to get it: Aim for 2-3 grams of combined EPA/DHA daily through supplements or fatty fish (salmon, mackerel, sardines) 2-3 times a week.

• Bonus: Omega-3s support heart and brain health, making them a no-brainer addition.

  
  

Sleep: The Silent Muscle Builder

You can’t out-train poor sleep. After 50, sleep quality often dips, but this is when your body repairs and builds muscle.

• Why it matters: Growth hormone and testosterone peak during deep sleep. Skimp on rest, and you’re robbing your gains.

• How much: Target 7-9 hours nightly. Quality counts—ensure a cool, dark room, and ditch screens an hour before bedtime.

• Hack: If sleep’s elusive, try magnesium (200-400 mg) or a small dose of melatonin (0.5-3 mg) to help you wind down.

  
  

Diet: Fuel the Machine

Muscle doesn’t grow on air. Your diet needs to deliver protein, calories, and nutrients—without excess junk.

• Protein: Aim for 1.2-1.6 grams per kilogram of body weight daily (e.g., 90-120 grams for a 75 kg person). Spread it across 3-4 meals—eggs, chicken, fish, lentils, or whey protein work well.

• Calories: You need a slight surplus (200-300 extra calories) to build muscle, but don’t overdo it—fat gain sneaks up faster now. Track your intake for a week to find your sweet spot.

• Carbs and fats: Carbs fuel workouts (unless you are keto adapted); healthy fats (avocados, nuts, olive oil) support hormones. A 40/30/30 split (carbs/protein/fat) is a solid start.

• Timing: Post-workout, pair protein (20-30 grams) with carbs (40-50 grams) to kickstart recovery.

  
  

Putting It All Together

Here’s a sample day for a 50-year-old looking to pack on muscle:

• Morning: 3 eggs, 1 gram omega-3 supplement.

• Pre-workout: Homemade meal – avoid excess sugar and artificial ingredients.

• Workout: Squats, bench press, rows (3 sets each, 10 reps).

• Post-workout: Whey shake (25g protein), 5g creatine.

• Dinner: Grilled salmon, quinoa, and spinach.

• Night: 8 hours of sleep, magnesium if needed.

  
  

Final Thoughts

Building muscle after 50 isn’t about turning back the clock; it’s about stacking the deck in your favor. Train smart, eat well, sleep hard, and use tools like TRT, creatine, and omega-3s wisely. Progress might be slower than in your 20s, but it’s far from impossible.

Your body’s still got fight left. Give it the chance to prove it.
