Excellent app, very complete.

Very complete application.
Many exercises (no equipment needed) Effective for the whole body: upper body, abs, legs, or the whole body, as well as warm-up exercises and "relaxation".
All types of tours are offered (Tabata, high intensity, max repetitions, maximum time), and one can choose the level of difficulty / intensity.

There is also the option of creating their own circuits and exercises A to Z, and you can follow his training, and his physical (weight, BMI, IMG ...).

Confirmed practicing of Martial Arts, I use every day to work this way, and some of these exercises, which are based in fitness workouts.
The effectiveness of this method is real.

Inexpensive, comprehensive, customizable, adaptable to all (from beginners to high level sports) and especially effective.
I highly recommend this app!
