Teens (14–18)

Building athletic foundation + bone density

Training Protocol

Bodyweight mastery first, then basic barbell movements. Focus on movement quality, not load. 3x/week full-body. Sports-specific conditioning. Growth plates are still open — avoid maximal 1RM attempts.

Nutrition Strategy

Caloric surplus is natural (growing). Protein 1.4–1.6g/kg. Calcium 1300mg/day (bone growth peak). Avoid supplements except Vitamin D if deficient. Real food first.

The Key Insight

Consistency + form > intensity. This is the decade your bone density peaks — weight-bearing exercise now pays dividends at 60.
