Sit ups
By far the best sit up app on the market. Once you buy the goal setting kit your smooth sailing. This app has helped me learn disipline and hard work and Ive only had it for 2 weeks. With this app Ive been to go from 1 sit up to 20 by increase my goal every 2 days. Way worth the money for the add ons and thanks to the creators
