Depth jump

Log this in the tracker

A drop from a box straight into a maximal jump, the classic plyometric.

What it is

You step off a low box, land, and immediately jump as high as possible. The aim is minimal ground contact time, training the stretch-shortening cycle.

Muscles worked

Primary: Quadriceps, Glutes, Calves. Secondary: Hamstrings, Core.

How to perform it

  1. Set a box between twenty and forty centimetres high, in a clear space.
  2. Step off, do not jump off, and land on the balls of both feet with soft knees.
  3. The instant you land, jump as high as you can with the arms driving up.
  4. Land the jump softly, then step back onto the box and reset before the next rep.

Common form faults

  • Sinking into a deep squat on landing before jumping. Aim for a fast, shallow bend. If you sink, the box is too high.
  • Doing sets of twenty as conditioning. Keep sets short and rest fully. Fatigued plyometrics stop training power and start risking injury.

Programming

3 to 5 reps a set, 3 to 5 sets, fully rested, early in a session. Build a base of strength before adding depth jumps.

Frequently asked questions

How high should the box be?
Low enough that you jump higher than you dropped from. Twenty to forty centimetres suits most people; higher boxes usually slow the contact down.
Are depth jumps safe?
For trained legs and short sets, yes. They are demanding on the tendons, so build up jump volume gradually and skip them when sore.
