I like the SI6 videos, too. I don't use them everyday...just no time for that. It has helped me a lot, especially with arm strength. When I started the "start it up", I just about collapsed on push-up #2, but now I am almost completely keeping up with "Ramp it Up". I've been at it for more than 6 weeks, but there was no way my body was going to slim in just 6 weeks!!! I like doing the "Ramp it Up", but I switch to "Slim and Limber" instead of doing the yoga at the end of "ramp". It gives me a more satisfying stretch. Fun stuff!
