Tuck Jumps Knees Up

From a standing upright position, squat slightly, no more than about the quarter squat level, then immediately drive upwards.

Aim to bring the knees as high as possible, using your arms for both balance and to aid in lifting yourself off the ground.

Concentrate on keeping your back straight, and landing with both feet.

On landing, explode up again, or take a small bounce before taking off again (easier), by bouncing you will reduce the effectiveness of this exercise, you should aim to gradually build up the amount of reps you can perform, however always perform each rep with good technique.

Remember the aim is to achieve height during the jumps, once tired rest, as poor technique results in injury.
