I'm on my 4th rotation of STS starting meso 3 next week. This is the only weight training I've done obviously for quite a while and though I love STS I think I need a change cause I don't think I'm shocking my body anymore even though I've increased my amount of weight lifted with each rotation. my question is when I start doing all my other cathe dvds like MM,ME etc and circuits, what percentage of my 1RM should I lift. I definately don't want to lose the toned muscles i've gotten from sts, but I would like to lean out more, I'm thinking of doing fitnessfreaks get ready for summer rotation. Thanks for any suggestions or comments
