Make every minute count with the J&J Official 7 Minute Workout app. The library features a selection of 22 preset workouts with different levels of intensity and duration. All of these are made to fit the user's busy schedule, though, as they last only from 7 to 32 minutes.

You may even customise your own workout, allowing you to concentrate on your focus areas, and you can utilise more than 70 exercises to come up with over 1,000 variations. Moreover, you can set notification reminders to keep you going.

There are 72 video tutorials you can follow, too. Plus, the app allows you to control audio prompts as well as music from your mobile device.
