I am constantly doing it in practice and have nasty bruised on my right forearm. I mean ugly enough for my kids ped. to ask suspicious questions. I guess they look like I have been man handled. Nasty, green old brusies, with red/purple new ones on top. Plus they HURT! And seem to never heal with 3 practices a week.
Anyway, any suggestions besides, don't hit the lane line? Is there some kind of arm armour for swimming?
