The Scientific 7-minute Workout by Gretchen Reynolds is All One Needs

The Scientific 7-minute Workout by Gretchen Reynolds boils an entire workout at the gym down to twelve simple exercises that uses one's own weight, a chair and a wall to get maximum results. The article by Reynolds is based off of conclusive scientific studies that seem to prove that short, powerful workouts are all someone really needs to get the kind of great results they crave from long stints at the gym.

Speaking about the process as a whole, Reynolds explains that, "...even a few minutes of training at an intensity approaching your maximum capacity produces molecular changes within muscles comparable to those of several hours of running or bike riding." So, while it might take the majority of your energy to do the workout, it appears that less might be more when it comes to getting ripped.
