I really like Low Max - and if your knees are delicate, you can always do it with out any risers - just the step or just use a rug or towel. The music is great, and you've got all your friends working out with you! But as mentioned, check out the video clip to see what it looks like so you can decide if it is something your body will be okay doing.
I also have LIC and love it as well. I don't know why, but if I am in a hurry I prefer just doing a step or kickbox workout, I guess because of the time it takes to get out my weights. Having said that I love circuit workouts - great calorie burn...so if I have a bit more time I'll do the circuit type workout and if feeling rushed, I'll go for the straight cardio. Love having the option of being able to do either.
