Great workout app!

Ive been kickboxing for 2.75 years and am very impressed with this app. Its easy to use with logical configurations & options. Ten three-minute rounds with 30 second rests in between works best for me to drip with sweat... just how I like it! The combos are quick and easy to follow, and the random order to the combos keep me sharp. Get this app if you have any interest in boxing - you wont regret it!
