Ive had this app for the longest time, but only started using it a week ago.
Now I regret not using it before! Its quick and effective.
I have tons of other ab apps, tried them all out last week, but this is hands down the B-E-S-T.
Other perks are that you can preview each exercise video before beginning; and theres a pause/play button if you need it.
Also, everything is configurable: intensity of each exercise, rest time (0-60sec), workout length (3, 5, 8min), fitness level, and a selection of equipment (11 items) you have available.
I regret not using this long-ago, youll regret not buying this sooner
