Since the contents of the dvds have been described, I'll just go straight into what I think of them.
The workouts are pretty hard core. They start with a warm up and the intensities progress up immediately afterwards. The exercises are grouped together by sets, and cover aspects like strength, power and endurance. You're even given water breaks! What I was most impressed with, is their choice of the support trainers/demonstrators. There are men and women of different build and abilities, and they just train together, and it's all cool. That kind of an "all inclusive" and "non-judgemental" attitude is quite a breath of fresh air.
Two things I would like to have seen more of, are kicks and flexibility drills. I would like to have seen a greater variety of kicks being involved, then again these aren't "instructional" dvds, rather, they are workout dvds that you can put on and follow.
All in all the training programs are great to follow by yourself if you're starting out, and want to improve your strength and stamina, with very little equipment.
