With fitness and life, it’s always important to keep things fresh. Yesterday, I tried a new exercise that I saw in the Nov 2011 issue of Men’s Health: the Bosu medicine-ball twist. Before yesterday, I had no idea what a Bosu ball was. It’s essentially half of a swiss exercise ball with a small circular platform attached. Essentially, the exercise involves mounting the ball (which is easier said than done) with a 10 or 15 pound weight, standing flat on the ball with a slight bend in the knees & hips, and rotating the upper body as far to the left and right as possible. Throughout the exercise, it’s important to keep one’s hips forward and use only the core. I did about 10 reps on either side. What was amazing is how much energy, core especially, it takes to simply balance on the Bosu.
