Ball Exchange

It is very similar to the V Sit-up, which is the exact same movement, only without the ball. The exercise ball adds 2 things to the movement that increase its effectiveness:

1) Neuromuscular Coordination. You simply can't do this exercise properly without coordinating a lot of different muscles all at the same time. See this post for more on the benefits of neuromuscular coordination.

2) Peak Contraction. It is very easy to start getting sloppy when doing these types of movements, especially when you start to get tired. However, by having to physically move the ball from your hands to your feet, and then back again on every repetition, you have no choice but to stay in that peak contracted position for one full second.

Between the use of both ends of the abdominal muscle wall, the increased neuromuscular coordination, and the added advantage of holding that peak contraction, this exercise is voted one of the best when it comes to making true progress in the abdominal area!
