Bosu Rules!! Have you checked the exercises from their website:http://www.bosu.com/scripts/cgiip.ex...l?article=2408
One of the cool things about Bosu is that when the round side is up, you can integrate strength and balance, with the platform side up, you have a more extreme balance toy, similar to a wobble board.
For training reaction time, have someone throw a medicne ball to you as you stand on it! Also, check out the ab training:http://www.bosu.com/scripts/cgiip.ex...?article=2405#
Pertinent for skiers is lateral strength and stability. People are usually so weak in their external obliques, that theyfind side bends on the stability ball close to impossible. On the Bosu, you can lie on your side, with your hip touching the side of the bosu. Supporting arm extended, ear resting on arm, top arm extended, palm facing down, arm next to ear. Knees are bent, inner legs contracted to engage deep core muscles.
Inhale to prepare. Exhale, draw navel to spine. Iniate action from the lowest point of your waist, NOT form any lateral movement of your neck. Do a side bend, allowing the top hand to touch the top hip. shoulder should line up with hips, neck should line up with spine, as opposed to being foward. Inhale return, reach top arm back over head.
