Figure I'll start out with I'm not into bodybuilding, however, I am into creating reasonable symmetry in order to limit imbalances that could lead to injuries.
When I started lifting I was same height, 6' but at 117 lbs. Probably fell into the skinny category. Been training since about September of last year. Had a 2-3 month break from May to June from a lumbar strain. Currently at 143 lbs. 6'.
Focus is on getting strong, if I gain weight doing so, so be it. But no concentration on gaining weight atm as it's not inline with my primary goals.
