One

Starting Position: Place a BOSU^® balance trainer on the floor 3-6″ in front of your feet on a non-slip surface. Stand with your feet hip-width apart or closer, arms by your sides, depress and retract your scapulae (pull your shoulders down and back) without arching your low back, and “brace” (engage your abdominal / core muscles) to stiffen your spine.

Two

Downward Phase: Begin your downward phase by first shifting your hips backwards then slowly moving downwards to create a hinge-like movement at your knees. Continue to lower yourself until you feel your heels about to lift off the floor. Try to maintain a flat back by bending forward at the hips, keep your head facing the BOSU directly and position to your arms where comfortable or where they offer the greatest degree of balance support.

Three

Jumping Movement: With ONLY a very brief pause at the bottom of your downward phase, explode upwards through your lower extremity onto the top of the BOSU, achieving triple extension (pushing and extending your ankles, knees and hips simultaneously). As your jump into the air, keep your feet level with each other and parallel with the floor, but bring them together to land on the top of the BOSU.

Four

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

Five

Attempt to land softly and quietly on the mid-foot, rolling backwards quickly towards the heels to create a level foot, parallel with the floor. Always push your hips backwards and drop your hips to absorb the jumping forces. Avoid locking out your knees or quads on your landing as this may lead to potential knee injuries.

Six

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.

Seven

Exercise Variation: As you develop your jumping and landing skills, you can progress the exercise intensity and complexity by: (1) driving your arms behind you during the downward phase (illustrated), (2) driving your arms forward (illustrated) or upward (towards an overhead position) during the jumping phase, or (3) driving your knees towards your chest during the jumping phase.
