for those who have tried both do you find one system any better than the other for improving our Aerobic base.
I've tried the spinervals 16.0 and I do not find the works out too bad.... I'm not able to follow the prescribed gears but I do feel I'm getting a solid work out. and I'm in my Aerobic range
I'm considering picking up more of the DVD's as Xmas gifts so is one system superior?
