re: OT trainers how do I get my body to look like this for summer?

This is my Shoulders routine:

Dumbbell shoulder press, 3 sets of 10
Dumbbell lateral raise, 3 sets of 10
Upright rows with EZ bar, 3 sets of 10
EZ Bar underhand press, 3 sets of 10
Rear delt raise, 3 sets of 10
Shrugs, 3 sets of 10

That's just off the top of my head. I do stuff on machines too.
