So this is my story... When i first started playing tennis my shots were always flat. My coach saw that all i did was flat forehands so he decided to teach me the windshield wiper forehand so i could add spin to my game and make it not 1 dimensional. The thing is that ever since that day i have been using the windshield wiper forehand and i can't do the flat forehand as it feels uncomfortable and i feel like i have to overgrip the racquet in order for it to not fly out. I use an eastern grip and would like to know how to do a flat forehand again so i can get more drive. Although my forehands have a lot of spin i still want to make it so i can do a topspin forehand or flat forehand when the time is right. Please help!!
