There is a great variety of exercises to keep these routines fresh and interesting! You can choose to have no break between exercises in the settings to amp up the intensity and make this a true 7 Minute Workout (otherwise it adds an extra 10 second break and takes about 10 minutes). If you work every exercise hard, you will be sweating when you finish!
