Hello, I love Cathe and find her workouts thorough, safe and effective. I consider myself a pretty advanced user - I have focused on strength/bodybuilding rotations (sprinkling in Cathe stuff) for many years. I've been reluctant to try the LITE strength workouts because I need to be challenged. I've read some reviews, and it seems like the Pyramid and Stacked workouts might be good for me as higher-rep/more metabolic strength days if I lift as heavy as I can. Can anyone advise? Thank you!
