Warning: Consult a nutritionist before making significant dietary changes, especially for intense fitness goals.
How Much Protein for Fitness Goals?
Protein is essential for fitness goals, supporting muscle repair, growth, and recovery. The amount of protein you need per kg of body weight varies by goal: 1.2–1.4 g/kg for endurance athletes (e.g., runners, cyclists), 1.6–1.8 g/kg for strength training (e.g., weightlifting), and 2.0–2.2 g/kg for body recomposition (muscle gain + fat loss). For a 70 kg person, this translates to 84–98 g for endurance, 112–126 g for strength, or 140–154 g for recomposition daily.
Factors influencing protein needs include:
- Fitness goal: Strength and recomposition require more protein than endurance.
- Training intensity: Higher volume or intensity increases protein demands.
- Calorie balance: A slight deficit or surplus adjusts protein needs for fat loss or muscle gain.
- Body composition: Leaner individuals may need higher protein per kg.
Protein supports muscle protein synthesis, reduces fatigue, and enhances recovery, making it critical for all fitness pursuits. For endurance, it aids in repairing muscle damage from prolonged activity. For strength, it fuels hypertrophy. For recomposition, it preserves muscle in a calorie deficit while supporting growth. Use our macro calculator to balance protein with carbs and fats for your specific goal.

Sample Protein Needs Table
Example protein needs for a 70 kg person by fitness goal:
| Fitness Goal | Protein per kg | Total Daily Protein (70 kg) |
|---|---|---|
| Endurance | 1.2 g/kg | 84 g |
| Strength | 1.6 g/kg | 112 g |
| Recomposition | 2.0 g/kg | 140 g |

Tips for Optimizing Protein for Fitness Goals
Meeting your protein needs for fitness goals requires strategic planning to maximize performance and recovery. Here are actionable tips to help you succeed:
- Choose high-quality sources: Opt for lean meats (chicken, turkey), fish, eggs, whey protein, or plant-based options like lentils and tofu to meet your protein needs efficiently.
- Time your intake: Consume protein every 3–4 hours, including 20–30 g post-workout to optimize muscle repair and growth.
- Tailor to your goal: Endurance athletes should pair protein with carbs for recovery, while strength trainers need higher protein for hypertrophy. Recomposition requires a balance with a moderate calorie deficit.
- Combine with exercise: Pair protein with resistance training for strength or recomposition, and include cardio for endurance or fat loss.
- Track and adjust: Use our macro calculator to monitor intake and adjust as your fitness level or body composition changes.
Tip: Check our high-protein diet guide for meal plans tailored to strength, endurance, or recomposition.
