Really good!
With this app I really liked how you could choose between 3 different options of workouts based on what type of training you were planning on doing. I also liked that you could create personal workouts as well, whether they were random or carefully put together. The main thing I did not like about this app is that it is pretty outdated and a lot of the exercises were plain and simple. I had already seen many of these exercises before, so in my opinion the app wasn't and isn't necessary for my workouts. Also, in order to get in a good 45-minute workout you have to do 3 or 4 of the workouts because each is only about 12 minutes.
