What adjustment can I make if my arm is lagging behind while my body is way ahead?
This actually may not be a problem. In fact, late arm lag due to late shoulder rotation is encourage and what so many hard throwers do. Tough to way without seeing, though… can you post a pic or video?
Ok ill try to get something up
If you arm is dragging due to early shoulder rotation, then you have to figure out what’s triggering the early shoulder rotation. Usually it’s postural or glove instability.
