Injury Prevention

Strength training for high school runners

Strength training in high school isn't optional. It's the most under-used injury prevention tool there is — and it builds the durable runner you'll be at 22.

How often

2-3 sessions per week, 20-30 minutes each. Done after runs, not before. Off-season can be heavier; in-season is maintenance.

Core exercises

Single-leg deadlift, split squat, step-up, glute bridge, side plank, dead bug, calf raise. Master bodyweight first, then add load.

Heavy is fine — actually preferred

Research is consistent: heavier, lower-rep work (5-8 reps) builds tendon and bone better than endless light reps. With supervision, high schoolers can and should lift heavy.

Plyometrics

Short, snappy plyos (pogo hops, bounds) build tendon stiffness and economy. 5-10 minutes, 2x per week, after warm-up.

Key takeaways

  • 2-3 sessions per week, 20-30 min.
  • Single-leg work is the highest ROI.
  • Heavy + low reps > endless light reps.
  • Plyos build the elastic, fast-feeling stride.
