The Scientific 7-Minute Workout
Not enough time in your day to exercise? All you need is 7 minutes, a wall, and a chair! The idea behind the workout is rapid bursts of intense exercise which have comparable benefits to the traditional time-consuming programs: twelve 30-second interval exercises broken up by 10 seconds of rest. There are even a number of great apps you can download on iTunes for free (7 minute workout timer) to keep you on track, or click here to get a workout plan.
