I was pleasantly surprised by the quality of the workouts available. You will work out quite a sweat.

I'm a fitness instructor myself and I'm always looking for new things for my clients to stay at work and motivated.. The entire line of runtastic apps are wonderful! I use them myself. Great!

I tried many exercise apps and these are by far the best! I love how each day is different, starting slow and increasing as you get stronger. I happily paid to upgrade both the Butt and Abs trainer. I really wish there was a version for arms, and would would gladly pay for one!

I love this app. The workouts are great and the fact that you can alter or write your own program is amazing.

It stops working !!! Please fix it .. I used to love this app and used for few month w no issues !!! Al All Of a sudden for the past few weeks it stops half way and "Basta!" It freezes .. I can t see the images or no instruction voice ! The music is playing in the background .. I tried to reload the app .., but it happened again ! It must be the app that's not working ! Same thing happened to the "leg workout " app. My abdomen app from you guys is working fine ! It's great apps ! But ... Are Not working ! Fix it !!!

This work out is quick & simple. I'm so sore, but it'll be worth it! It's a good hurt.
