Treilin put this together for me. Basically I've been working out at home for the past 2 years so I haven't been able to hit my legs or back as hard as I would like. So I was kind of surprised that she supersetted my leg workout. I'm also a little confused as to why I do cardio on 2 of my hardest days (legs and back). I always thought I should skip cardio on the heavy days. Or is it ok because it's before I lift?
