I'm an easy 86kg@179cm, not lean, not big enough.
I've put on 10kg weight (probabaly 50% functional/muscle) and 50-60kg to my squat 1rm in last 12months.
Legs are where a lot of the muscle has gone. Stick legs, gone up 2-3 pant sizes.
I've always done a powerbuilding type split, I do Squats,Bench,Deads,Military as a strength exercise using powerlifting cycle templates., accessories are more hypertrophy.
