Slow mo, forehand and backhand:
On the take back on the slow mo forehand, where is the added angle of the shoulder turn relative to the hip turn? That angle stretches strong core muscles for SSC use in the forward swing.
Djokovic uses a lot of that shoulder-hip turn angle difference. For many it could stress the back.
