Body core training for long distance shooting with the TenPoint Vapor RS470 and EVO-X CenterPunch Broadheads. This method has improved my long distance shooting drastically. I only shoot out to 50 yards off the ball but once control of your body core/balance is mastered it will take your (feet on the ground) off-hand shooting to the next level. It also increases the focus and concentration of the mental aspect of shooting. It will keep you in the shot much longer until you're able to bring all aspects of the pre shot in-line with with your breathing. There's no punching or jumping on the trigger as the crosshair floats across the target when you're on the ball, or you'll miss the target completely. Both knees on the ball was the toughest for me to master. Give it a try.
