While many people use 75 Medium for weight loss, it's equally effective for building muscle. Research from the Journal of the International Society of Sports Nutrition confirms that consistent training combined with adequate protein intake leads to significant muscle hypertrophy. The 75 Medium framework provides structure, consistency, and accountability—three keys to muscle growth. Here's how to optimize it for gains.

Can You Build Muscle on 75 Medium?

Absolutely. Here's why 75 Medium works for muscle gain:

75 Medium Advantages for Muscle

  • One workout per day: Allows proper recovery between sessions
  • 45 minutes is optimal: Research shows diminishing returns after 60-75 min
  • 22 flex meals: Can align with higher-calorie days
  • No mandatory outdoor workout: Gym-focused training allowed
  • Daily consistency: 75 days of progressive overload = significant gains

💪 Realistic Muscle Gain

Natural muscle building happens slowly. Expect:
Beginners: 1-2 lbs muscle/month
Intermediate: 0.5-1 lb muscle/month
Advanced: 0.25-0.5 lb muscle/month
In 75 days, 3-5 lbs of new muscle is an excellent outcome.

Key Differences from Weight Loss Approach

Factor Weight Loss Muscle Gain
Calories Deficit Surplus or maintenance
Protein High Very high
Cardio Moderate-high Minimal (walking)
Training Mixed Strength-focused
Recovery Important Critical

Nutrition for Muscle Growth

Muscle requires building blocks. You can't build a house without materials.

Calorie Requirements

  • Find your TDEE: Total Daily Energy Expenditure
  • Add surplus: 200-500 calories above maintenance
  • Lean bulk: 200-300 surplus minimizes fat gain
  • Aggressive bulk: 400-500 surplus for faster muscle but some fat

Macronutrient Breakdown

Macro Target Purpose
Protein 1-1.2g per lb bodyweight Muscle building and repair
Carbs 2-3g per lb bodyweight Energy, workout performance, recovery
Fats 0.3-0.5g per lb bodyweight Hormones, joint health

Sample Muscle-Building Day (~2,800 cal)

BREAKFAST (~700 cal):
- 4 whole eggs + 4 egg whites scrambled
- 1 cup oats with banana and honey
- Glass of milk

PRE-WORKOUT (~350 cal):
- Greek yogurt with berries
- Rice cakes with peanut butter

POST-WORKOUT (~500 cal):

TOTAL: ~2,800 calories
Protein: ~180g | Carbs: ~300g | Fats: ~90g
                    

Protein Deep Dive

According to the International Society of Sports Nutrition, protein intake of 1.6-2.2g per kg bodyweight maximizes muscle protein synthesis.

Protein Timing

  • Distribute throughout day: 4-5 protein feedings
  • Each meal: 25-40g protein minimum
  • Pre-workout: Protein 2-3 hours before (real food)
  • Post-workout: 30-50g protein within 2 hours
  • Before bed: Casein or cottage cheese (slow-digesting)

High-Quality Protein Sources

Source Protein/Serving Notes
Chicken breast 31g per 4oz Lean, versatile
Eggs 6g per egg Complete protein, cheap
Greek yogurt 17g per cup Probiotics, casein
Salmon 25g per 4oz Omega-3s, recovery
Lean beef 28g per 4oz Creatine, zinc, iron
Whey protein 25g per scoop Fast-absorbing
Cottage cheese 14g per 1/2 cup Casein, before bed

Hitting 180g Protein Daily

  • Breakfast: 4 eggs + egg whites = 32g
  • Snack: Greek yogurt = 17g
  • Lunch: 8oz chicken = 62g
  • Post-workout shake = 30g
  • Dinner: 8oz beef = 56g
  • Total: 197g

Training for Hypertrophy

Your 45-minute workouts need to be strategically designed for muscle growth.

Hypertrophy Training Principles

  • Progressive overload: Increase weight, reps, or sets over time
  • Rep range: 6-12 reps for hypertrophy (some 15-20 for isolation)
  • Time under tension: 2-3 second negatives, controlled reps
  • Volume: 10-20 sets per muscle group per week
  • Intensity: Train to 2-3 reps from failure

45-Minute Workout Structure

WARM-UP (5 min):
- Light cardio: 2-3 min
- Dynamic stretches
- 1-2 warm-up sets of first exercise

MAIN WORKOUT (35-38 min):
- 4-5 exercises
- 3-4 sets each
- 6-12 reps per set
- 60-90 sec rest between sets

COOLDOWN (2-3 min):
- Light stretching
- Mobility work

KEY: Minimize rest, maximize intensity within time limit
                    

Exercise Selection Priorities

  1. Compound movements first:
    • Squats, deadlifts, bench press, rows, overhead press
    • Most bang for your buck, hit multiple muscles
  2. Isolation movements second:
    • Curls, tricep extensions, lateral raises, calf raises
    • Target specific muscle groups

Workout Splits

Push/Pull/Legs (Recommended)

Day Focus Key Exercises
Mon Push (Chest, Shoulders, Triceps) Bench, OHP, Dips, Flyes
Tue Pull (Back, Biceps) Rows, Pulldowns, Curls, Face Pulls
Wed Legs (Quads, Hams, Glutes) Squats, RDLs, Leg Press, Lunges
Thu Push Variations of Monday
Fri Pull Variations of Tuesday
Sat Legs Variations of Wednesday
Sun Active Recovery Walking, stretching, mobility

Upper/Lower Split (Alternative)

Day Focus
Mon Upper Body (strength focus)
Tue Lower Body (strength focus)
Wed Light cardio/Active recovery
Thu Upper Body (hypertrophy focus)
Fri Lower Body (hypertrophy focus)
Sat Full body or weak points
Sun Rest/Walking

💡 Pro Tip: Active Recovery Days

Your "active recovery" days still need a 45-minute workout. Use this for: walking (counts!), yoga/stretching, mobility work, or very light cardio. This supports muscle recovery without taking a true rest day.

Recovery & Sleep

Muscle is built during recovery, not during workouts.

Sleep for Muscle Growth

  • Target: 7-9 hours per night minimum
  • Growth hormone: Released during deep sleep
  • Protein synthesis: Peaks during sleep
  • Testosterone: Sleep deprivation lowers levels significantly

🛌 Recovery Strategies

  • Post-workout nutrition: Protein + carbs within 2 hours
  • Hydration: 3L+ daily (your water requirement helps!)
  • Stress management: Your mindfulness practice reduces cortisol
  • Stretching/mobility: Include on active recovery days
  • Avoid overtraining: Listen to your body's signals

Signs You Need More Recovery

  • Strength decreasing over multiple sessions
  • Excessive soreness lasting 4+ days
  • Poor sleep despite being tired
  • Loss of motivation/interest in training
  • Mood changes, irritability
  • Increased injuries or nagging pains

Supplements

Supplements are the cherry on top—nutrition and training are the cake.

Evidence-Based Supplements

Supplement Evidence Dosage
Creatine Monohydrate Strong 5g daily
Whey Protein Strong As needed for protein goals
Caffeine Strong 200-400mg pre-workout
Vitamin D Moderate 2000-5000 IU (if deficient)
Omega-3s Moderate 2-3g EPA/DHA

Skip These (Low Evidence)

  • BCAAs (if getting enough protein)
  • Most "mass gainers" (just expensive calories)
  • Test boosters
  • Most pre-workout ingredients besides caffeine

💊 Creatine Facts

Creatine monohydrate is the most researched supplement with proven benefits for strength and muscle. It's safe, inexpensive, and effective. Take 5g daily—timing doesn't matter. Expect 2-5 lb water weight gain initially (this is normal and good for muscle).

Tracking Muscle Gains

Your daily progress photos document your transformation.

What to Track

  • Weight: Should slowly increase (0.5-1 lb/week ideal)
  • Measurements: Arms, chest, shoulders, thighs, waist
  • Strength: Log weights and reps for main lifts
  • Photos: Same lighting, same time, relaxed and flexed

Workout Log Essentials

  • Date and workout type
  • Exercises performed
  • Sets x Reps x Weight for each
  • Rate of perceived exertion
  • Notes (energy, pump, any issues)

Monthly Check-in

Compare photos and measurements monthly:

  • Are lifts progressing?
  • Are measurements increasing?
  • Is waist staying reasonable? (too much fat gain = reduce surplus)
  • Visual changes in photos?

🌟 Success Story

"75 Medium gave me the consistency I was missing." — Marcus, gained 8 lbs muscle
"I'd always trained sporadically—two weeks on, one week off. The daily commitment of 75 Medium meant I actually showed up every day. In 75 days I put on more muscle than I had in the previous year. The structure made all the difference."
