Well, my goal is primarily strength gain without mass gain. I'm a rockclimber, so I'm not looking for unnecessary bulk.
My program is essentially a strength-hybrid CrossFit. My affiliate typically follows the national WODs, and I'll work out with them 3-4 times a week. Twice a week I do 5x5 strength routines (typically squats & bench or deadlift & press), and I climb 2-3 times per week.
It's a lot of volume, so I spend a lot of time trying to optimize recovery. Lots of sleep, lots of protein, lots of fish oil. Historically I've never done a PWO drink, but lately I've been taking some milk with me to gym to have after a hard metcon, for glycogen replenishment. I wouldn't drink one after a strength workout or climbing.
On rock? Rock on
