Have been told to "bend the knees" and "stay low" most especially on low balls. 1. Maintain balance (okay im geeking out on this) -- lowering /bending your knees lower the center of gravity which makes you balanced / stable when hitting your shot. 2. Improve reach - Bending your knees makes it easier to reach and hit low balls effectively. Believe me, i've hit my shots without bending before. It's not helping my game 😣 #tennis #tennis🎾 #tennisplayer #tenniscourt #kneebend #bendtheknee #tenniscoach #tennisdrills #tennislove #tennislife #tennismatch #tennisgirl #tennistraining #tennisfan #tennisvideo #tennistime #tennisfun #tecnifibre #nikevapormax #benchactive #uniqloph #tennisracket
