Hi Alexis.
I probably wouldn't use Pure Strength much at all if it weren't for the DVD. I use PS in conjunction with going to the gym during my lunch break. So, I pick a few PS body parts to work in the morning at home(using the mix and match feature), and then I do the remaining parts at the gym during lunch. I never seem to use the body part combinations that were put on the actual tapes. I do recommend this DVD over the tapes.
