Android: You're probably familiar with the seven-minute, whole-body workout. We've shown you instructional videos and a timer to help, but if you're away from your computer, Scientific 7 Minute Workout for Android can help you get your exercise in anywhere, anytime.
The app piggybacks on the popularity of high-intensity circuit training and guides you through the seven-minute workout routine, complete with diagrams and instruction on how to do each exercise and for how long. You do get some customisation options though. You can set how long you want the breaks between exercises to be (five seconds is the default, but you can add more time if you want), you can go back or skip forward if you run into an exercise you don't want to do, and you can pause workouts and come back to them later if you choose.
Scientific 7 Minute Workout is free, although there's a pro version that's currently on sale for $1. The pro version includes a workout log so you can track your progress and voice commands that tell you when to break and when to move on to the next exercise in the routine.
