Activation: Whatever I feel like. Today is was medicine ball throws at the wall, others might be medicine ball slams, or light weight push press
A: OH Press (3RM 165, MTW 145)
B: Incline Bench (3RM 235, MTW 205)
C: Flat Bench (3RM 255, MTW 225)
Shoulders were in pain during the 3RM test week, but as the days go by, they feel better and better. I'm about to start week 3.
OP: I would say ditch the plyo pushups as your activation. For some reason, I can go pretty heavy on OH Press and feel fine, but if I did just a few BW pushups I get terrible elbow and shoulder pains.
