This app is amazing. I have been doing these kind of workouts since I was about 10. Im now 29. So Ive had nice abs my whole life. I used to get lazy & skip working out for months at a time, but now theres no excuse. This ab workout app takes a max of 5-10mins at most to do. & you see results in as little as a week. Everybody should use this app. So theres absolutely no excuse to not do these workouts. Highly recommend this app or similar. You wont regret it.
