Calculate Your Post-Workout Protein Shake
Build the optimal protein shake based on your goals, weight, and workout intensity.
Post-Workout Protein Needs
Research shows 20-40g of protein within 1-2 hours after training maximizes muscle protein synthesis. The "anabolic window" is wider than once believed — you do not need to chug a shake within 30 minutes. However, if you trained fasted, getting protein sooner matters more. For most people, 0.3-0.5g protein per kg bodyweight per post-workout serving is optimal.
Building the Optimal Shake
Muscle building: 30-40g whey protein + 40-60g carbs (banana + oats) + creatine. Weight loss: 25-30g protein + 10-15g carbs (berries) + water base (low calorie). Recovery: 30-40g protein + 30-50g fast carbs (banana + honey). Meal replacement: 35-45g protein + 30-40g carbs + healthy fat (peanut butter) for satiety.
The most overrated supplement in fitness is the post-workout shake — and the most underrated is total daily protein. Timing matters less than total daily intake. Whether you eat protein 30 minutes or 3 hours after training makes a 1-2% difference. Whether you hit 0.7-1.0g/lb daily makes a 20-30% difference in muscle growth. Focus on the total, not the timing.
