Meet your new best friend: the Bosu Ball is a half stability ball with a firm, flat bottom, and it is used for numerous strengthening and balancing moves. My personal favorite move is crunches on the ball.
Position the Bosu so the flat part is on the ground, and lie down with your back centered on top of the ball. Raise your legs up in the air at a 90 degree angle, so your core has to contract to keep you balanced. Place your arms behind your head (don’t pull on your neck though!) and do 50 crunches. The positioning might take some getting used to, but once you master the move, it will be so worth it. And in case my word isn’t enough to convince you, I’m going to let you in on a secret: Jessica Alba does this exact same move! And as you may have noticed, it works wonders on her.
