Hope you don't mind if I ask here, even though I'm not technically a BFL'er--you guys just seem to know so much about weight lifting.

My legs and abs have really responded to the workouts I'm doing (which include Pilates). But today the Pilates teacher commented on how relatively weak my shoulders and arms are. Yeah, I've noticed this, too. So how can I concentrate more on my UB? I'm already working it twice a week. Without straining myself by lifting too much weight, is there any way to safely do more? Or will my UB eventually catch up with my LB development? I'm doing a very standard gym workout with both machines and free weights.

TIA!
