Thank you so much Cathe! For example, on the biceps segment of Perfect 30 Perfect Pump Upper Body, I can match the weight you're using: 20's on the sweeper curls, 15's, 12's and 10's on the drop set curls, but I'm fighting for all those reps. I would like to be able to grow into using 20's a little more often, but I also know that form is critical and I don't want to risk injury either. Btw, I'm on a little trip back in time with your older workouts and I did Pyramid Lower Body from the Intensity Series and it never fails to give me a good burn in the lower body. I'm also planning to do some rotations using the Body Blast Series, CTX and Pure Strength. I started working out with you in 2009 and of course, Kick Punch and Crunch was the first of your workouts that I'd ever done and I was hooked. But I never really took time to do rotations using only those older series. Thank you for keeping me fit all these years! I'm looking so forward to pushing myself in order to get ready for STS 2.0!
