Eh?
Of course if no contact (bridge is made) and you strike and hit the target... great. But how many times have you fought, or sparred, and moved around picking off a guy with strikes while none of his get even close to you, and thus you've had no need to bridge an attacking arm? Or how many times have you landed multiple strikes and the opponent never intercepted any of them?
I think, to be honest, you should stick to the boxing gym and do what they are telling you. Stick with that skipping, Graham.
