Thank you for the replies. Now I understand the need to be watchful about too much volume too fast.
I'm still not clear on how to split things up, however. For example, in the double day squats cycle recently posted, looking at day 1, would you:
Front Squat - 80% x 1
Snatch - heavy single; 80% (of hs) x 1 x 3
Segment Snatch Pull (knee) + Snatch Pull - 90% (of sn) x 1+2 x 4
Back Squat - 90% x 1, 75% x 3 x 3
Good Morning - 3x5 (very light)
Maybe I'm thinking about this too much and need to just figure out what works for me. I'm still fairly new to this though (little over the year mark) and don't want to shoot myself in the foot with inefficient programming.
