Thanks I tried this but I feel on the backswing keeping the racquet above my shoulders on the pull back and then hitting through is better
I tried the allowing the ball and the loop but it seemed I became more lazy inmy preparation if that makes any sense . Maybe with more practise ?
Some pros go straight back, then forwards, for a PRO level shot, both serves and groundies.
While other's employ a C shaped loop, ATP takeback, or continous loop.
Try them all, find the best for you, then practice it a lot.
