Best to join a gym and get some good training, or, as I said earlier, seek out Coach Staley.
Took the words out of my mouth brotha. Olympic lifts! Olympic lifts! and some plyometrics! Explosive energy is where it's at. Plenty of really silly strong guys can't throw far. They are strong, but lack the ability to fire like a cannon. You need to train your muscles to produce their max energy very quickly, and Olympic lifts will do that. Jump shrugs are a really good exercise too.
