How to do it
Box jump. Targets type-II fibres. Develops power and contraction speed. 3-5 max-quality reps.
Muscles worked
Mainly cuadriceps. Train it inside a balanced routine to progress safely.
Recommended sets and reps
As a compound lift, it fits in 3–5 sets of 5–12 reps leaving 1–3 reps in reserve (RIR). Prioritize it at the start of the session, when you're fresh.
Common mistakes to avoid
- Letting the knees cave inward (valgus) when pushing, instead of keeping them tracking over the feet.
- Using too much weight at the cost of technique and full range of motion.
- Doing reps too fast, without controlling the eccentric (lowering) phase.
