Build the athletic foundation that pays dividends for years.
Strength training for teenagers is one of the highest-return investments in athletic development — if it is done correctly. Research is clear: properly supervised resistance training during adolescence improves performance, reduces injury risk, and builds the movement literacy that distinguishes good athletes from great ones.
This program is for athletes aged 14-18 across any sport. Three days per week, full-body sessions, built around technique mastery first and load second. The first four weeks are intentionally moderate in intensity — not because teenagers cannot handle more, but because building neural patterns correctly takes priority. Load increases systematically from week five onward.
The program emphasizes athleticism alongside strength: single-leg work for sport-specific stability, explosive movements for power development, and posterior chain work that prevents the ACL injuries that disproportionately affect young athletes. If you play a sport, this program makes you better at it.

Common Questions
Yes — research shows resistance training is safe and beneficial for adolescents when technique-led and appropriately supervised. Concern about growth plates is largely unfounded for standard strength training loads.
Strength training improves force production, deceleration ability, change-of-direction speed, and injury resilience. Every sport benefits from these adaptations. The program includes unilateral and explosive work that transfers more directly than bilateral machine training.
No — it supplements it. Fit strength training around your sport schedule. On days you have practice or games, this takes a back seat. Three sessions per week is a guide; adapt to your season.
Start with bodyweight and light loads only. Use the first 4 weeks as a technical foundation course. Film your form and add load only when your technique is clean. There is no award for lifting heavy before you are ready.
You need more food than you think. Teen athletes are still growing while adding training load. Prioritize protein (0.7g per pound of bodyweight), enough carbohydrates to fuel training, and enough total calories to support growth. Under-fuelling is the biggest mistake young athletes make.
