15-Minute Workouts to Boost Your Metabolism and Speed

Running out of time to get in a proper workout is a problem of the past. Now, all you need is an efficient and effective 15 minutes to get your heart rate up and metabolism moving.

The phrase, "exercise is better than nothing," is true—to an extent. The quality of movement is equally, if not more important, than just working out.

If you go out and perform 100 weighted squats and run 10 miles without any sort of warm-up then you're asking for an injury. A proper warm-up mixed in with effective and efficient work will do your body good.

Flipping through a magazine on the treadmill while you walk at 3 mph for 45 minutes isn't going to get you those 6-pack abs you crave. Instead of a 45-minute magazine reading session, you should do a quick and proper warm-up in, challenge yourself with 15 minutes of intense intervals, and then get out of the gym.

When you're crunched for time, challenge yourself with the following 15-minute workouts.

Just because these circuits are short in duration, doesn't mean you should do them everyday. Like everything else in life, your body needs balance. It needs to be pushed at times and then it needs time to relax, recover, and improve. Important factors such as your goals, injury background, and current fitness level aside, aim to complete these short, intense routines 2 to 3 times per week.
