OK.

Well, I just changed my routine about 2 weeks ago and Im getting ready to go out of town for like a week this week so that will also throw it off. I plan on changing it up like a month from when I get back. I will try the different rep/sets. The only leg machines I do are the ones where you're like in stirrups and you have to close your legs (inner thighs) and the opposite machine (outer thighs).

Dont yell at me about free weights yet! Im just getting the hang of the machines !
