I enter them in every workout but I don't see the saved results on the website.
I just figure that the important thing is to keep moving, to burn calories, etc. It's not like you are rehearsing for a show and you need to get the moves down.
Gaiam also has streaming/roku. They generally make good videos.
Answer this question (please read answers below before posting)...
I have this problem as well. Sometimes I just do the lunges/squats, but not as deep and not as many. Or I just do something else entirely while they are doing lunges. It sucks though.
