Or you could just tear your bicep right off your arm by swinging that shyt like that. Man if you aren't juiced and retaining a shyt load of water in your joints - doing that type of movement just looks like a tear waiting to happen. Being that you can swing and move the weight via momentum you can potentially move more weight than you should normally be able to handle, and if your joints aren't all lubed up from steroid induced water-retention, that down stroke part of that movement can tear your bicep if you have to heavy weight.
actually the water aint gonna help you if you ARE going to tear your bicep. anabolics predispose you to this type of injury BECAUSE you can use more and more weight and muscle strength surpasses tendon strength.
i agree with you though. it could be dangerous to jump right into this style of training with excess weight. foxy had been doing that style of training consistantly for a long time though and thus his connective tissues and tendons could cope better.
you can't argue with results.
