The Pushups app for BlackBerry is a training regiment to help you reach 100 pushups. The app gives you a graph and encouragement to reach 100 pushups in a six week time frame. With only 30 minutes per week, this app is going to help you get more fit and reach triple digit pushups.
One feature that is missing from this app is Twitter integration. Ideally, the app would tweet each time you reach a benchmark of pushups. Also, at $6.99 (currently on sale for $3.99) the app is a little on the pricey side.
