Right, his elbows bowing outward as he gets under the weight does nothing for his biceps. He's literally just lifting with dumbbells. Give him a 30lb and force him to use proper form, he'll get maybe one or two curls per set at most. He's unknowingly cheating himself wasting his time if he wants dem jeet street shitting guns to grow. Let em be dumb.

You don't get muscles like that (even with bad form, steroids, etc) if you can only handle two 13,6 kg curls...
He's weak. He'll need to drop to 20 for proper ten rep sets so he can build some muscle 💪
