Yes, but how MUCH are you eating?
You have 30ish lbs on me yet my lifts are all equal to or slightly greater than yours (and steadily climbing). I've only been on SS for 1.5 months after losing 15 lbs (most of which was muscle) during basic training. If, after 7 months of SS, you are stuck at a 200lb squat, you are doing something wrong. My guess is that you just aren't eating enough.
