- I rarely do much to focus on my arms. Most of my training is compound movements: bench press, overhead press, pull ups, rows. I do train CGBP, which is more triceps-oriented than my main grip for bench press, but I know with certainty I can make my triceps work harder in isolation exercises. Despite not doing a lot to isolate my arms, I'd say they're proportionally a bit bigger than my chest and shoulders.
- Not very.
- Being either anal retentive about technique or just swinging weights around and not knowing there's a useful space between those extremes.
- No. I really should, though, because my forearms are near non-existent.
