Step 1

Starting Position: Stand facing a raised platform or a plyometric jump box, place your right foot on the top of the step or box, keep your left foot on the ground, hinge from the hips to lean forward, keep your arms by your side and your head level with your eyes looking at a point on the ground two-to-three feet in front of you.

Step 2

Upward phase: Jump straight up into the air by explosively pushing your right foot in to the top of the box to create triple extension (ankle plantarflexion, knee and hip extension) while simultaneously pushing off with your left foot and swinging both arms up and in front of your body to generate upward momentum.  As you jump into the air lift up your left leg in order to keep your feet level with each other and parallel with the floor.

Step 3

Landing: The most important components of the landing phase are correct foot position and avoiding excessive forward movement in your lower extremity which places additional stresses upon your knees.

Step 4

Landing phase: Attempt to land softly and quietly on the mid-foot, rolling backwards quickly towards the heels. Always push your hips backwards and drop them downwards to absorb the impacting forces associated with jumping. Avoid locking out your knees or quads on your landing as this may lead to potential knee injuries. Land with your trunk inclined slightly forward, head aligned with your spine and back rigid or flat. Keep your abdominal / core muscles engaged, stiffening your torso to protect your spine.

When jumping keep your spine straight and tall by contacting your abdominals (bracing) and be sure to perform the same number of repetitions on each leg.
