Negative Positive
Title: The only wokout series you will need.
Review: I've used this video series for about 2 years. The workouts are extremely challenging,except for the "stretch" workout. If you want to get in shape, this is the one. I am a chiropractor. 3 of my patients are marines, and they train with this series. I turn 58 years old soon, so I don't usually do an entire workout. If you do the warm up and then 3o minutes of any of these workouts, it will be plenty for most people. Don't forget, you've got a pause button when the workout gets too intense.
