High-intensity circuit and resistance training:

- Simple and clean interface,
- Adjust intervals

The principle:

Do a strength exercise like a squat repeating the motion for a certain amount of time, rest, and then do another strength move. It’s different than traditional resistance training because the rest periods are shorter—usually less than 30 seconds—and the exercises chosen work large muscle groups in order to raise your heart rate. This approach combines aerobic and resistance training into a single exercise routine.
