I have done every type of workout that there is and I can say that these 4 DVDs rock! You will think you're not doing much and then are hurting for two days after. I am a long-distance cyclist and these have helped improve my quad and ham strength. Just go get em and try. You have spent more than 36 bucks on a bad dinner! Totally worth the results...Go now! :)
