Protein is the most important macronutrient for strength athletes. It provides the amino acids required for muscle protein synthesis — the process by which the body repairs and builds muscle tissue in response to training. For American and Canadian powerlifters and weightlifters, getting protein intake right is as important as getting training right.
How Much Protein Do Strength Athletes Need?
The evidence-based recommendation for strength athletes is 1.6-2.2g of protein per kg of body weight per day (0.7-1.0g per lb).
| Body Weight | Minimum (0.7g/lb) | Optimal (0.9g/lb) |
|---|---|---|
| 150lbs (68kg) | 105g/day | 135g/day |
| 180lbs (82kg) | 126g/day | 162g/day |
| 200lbs (91kg) | 140g/day | 180g/day |
| 230lbs (104kg) | 161g/day | 207g/day |
A 2017 meta-analysis in the British Journal of Sports Medicine confirmed that protein intakes above 1.62g/kg/day do not produce additional muscle gains in most strength athletes.
The Best Protein Sources
- Meat — chicken breast (31g/100g), beef (26g/100g), pork (27g/100g)
- Fish — tuna (30g/100g), salmon (25g/100g), cod (18g/100g)
- Eggs — 6g per egg. Complete protein with excellent amino acid profile
- Dairy — Greek yogurt (10g/100g), cottage cheese (11g/100g), milk (8g/cup)
- Protein supplements — whey protein (20-25g per serving)
Protein Timing
- Post-training — 30-40g within 2 hours of training
- Distribute across meals — 3-5 meals per day, 30-40g per meal
- Pre-training — protein-containing meal 1-3 hours before training
Pre-Sleep Protein
Research in Medicine & Science in Sports & Exercise confirms 40g casein before sleep increases overnight muscle protein synthesis by ~22%. Best sources: cottage cheese, Greek yogurt, casein powder. Consume 30-40g 30-60 minutes before sleep.
Protein Supplements
- Whey protein — fast-absorbing, best post-training. 20-25g per serving
- Casein protein — slow-absorbing, best pre-sleep. 30-40g per serving
- Plant protein blends — pea + rice for vegetarian and vegan lifters
Look for NSF Certified for Sport or Informed Sport certified products — important for USAPL and CPU competitors.

FAQ
How much protein do I need as a powerlifter?
0.7-0.9g per lb of body weight per day. A 200lb lifter needs 140-180g per day.
Can I get enough protein without supplements?
Yes — whole food sources can meet daily targets. Supplements are convenient but not necessary.
Is whey protein legal in USAPL competition?
Yes. Look for NSF Certified for Sport or Informed Sport certified products.
Does protein timing matter?
Less than total daily intake. Hit your daily target first, then optimise timing.
Final Thoughts
Hit 0.7-0.9g/lb per day, distribute across 3-5 meals, 30-40g post-training, 40g casein before sleep. The IronLifter 1 for squats and the TurboLifter 1 for deadlifts complete the setup.
