Single Leg Box Jump
Description
The single-leg box jump is an advanced plyometric exercise where you jump onto a box from one leg. It builds tremendous unilateral power, balance, and ankle stability. It demands perfect landing mechanics and should only be attempted after mastering two-leg box jumps.

Single Leg Box Jump Instructions
- Stand on one leg facing a box (start with a low box — 12 to 18 inches).
- Slightly bend your standing knee. Swing your arms back to load the jump.
- Explosively swing your arms forward and up while pushing off your standing leg.
- Jump onto the box, landing on the same single leg you launched from.
- Land softly with a bent knee to absorb the impact. Stick the landing.
- Step down (do NOT jump down) — protecting your knees and ankles.
- Reset and complete all reps on one leg before switching.
- Use low reps (3 to 5 per side) — this is a maximal-effort exercise.
