It's just strange to see someone press 160's, (which involves massive shoulder strength) then turn and claim 20's for laterals. Thats why I asked about technique.
Sometimes I do the seated side into front raise overhead back into side lat movement, then I'll use 20's max.
I hear what you're saying. Going "light" on shoulder day is unorthodox for what you see most guys in the gym doing. My belief is that we'd see a whole lot less labrum tears and rotator cuff ailments if guys backed off on the heavy stuff for delts.
I realize we're using subjective terminology in these posts though (heavy, light, etc). I focus in rep ranges where I want to failure...with delts I want to fail anything over 20 reps. So for me, 20lb dumbells do the trick.
What rep ranges do you use for shoulders?
