Calculate Your Protein IntakeFor skinny individuals, the biggest barrier to muscle is usually eating enough total calories, not a lack of protein specifically. Hit your protein number, then focus on adding calorie-dense foods so you are reliably above maintenance every day.

- Protein target: 1.6-2.2 g/kg per day
- Total calories are the main limiter for hardgainers
- Use calorie-dense foods and liquid calories
- Train progressively and be patient
