Biggest myth in basketball that lifting weights screws up your shot. That conclusion is made by seeing a meat head at the gym awkwardly shooting a basketball and thinking, "He lifts weights. He sucks at basketball. Lifting weights make you suck at basketball."
:crazy:
It can screw with your jumper if you don't do it right. If your lifting in-season, you must shoot right afterwards to allow your muscles to stretch out and keep your form. If you lift and neglect shooting, it throws your shot off with both form and feel.
