Holy Crap I thought I was going to die when I tried this video. My sister bought this video several years back and at the time I considered myself in pretty good shape. I exercised daily and loved doing aerobics and weightlifting classes. So, one day I decided to try this video. I think I made it about a half-hour into the video and quit because I thought I was going to collapse.Then I found out my sister had tried it with her friend and they lasted about 15 minutes before they gave up. Then I found out my mother tried it and she only lasted about 5 minutes. It has sat on the shelf unused since.Basically, unless you're like at an Olympic fitness level, I wouldn't even attempt this video. It's just too hard.
