Just a little bit past the service line, weak reply from your opponent thats almost a half lob, you are lining up your forehand and getting ready to crush the ball because it has "hit a very aggressive shot" written all over it.. Do you jump and hit the ball a higher contact point like the pros do when they go for it? Or do you take it early and hit it with your feet staying on the ground? Or let the ball bounce high and hit it when it comes back down to your strike zone area? I always jump for whatever reason and rip it to one of the corners but giving myself some margin for error. Problem is I sometimes lift my head when i do this, because so much movement and torque is involved, sometimes resulting in an error. Pros do it while keeping their head fairly still! So should I just learn to keep my head still or should I not lift off the ground on these shots?
