return start grip

most players wait to return serve with a forehand grip– here Kohlschreiber is waiting in a backhand grip– I also do this

core balance

on the one handed backhand ideally keep your shoulders level and your shoulders over your hips– a tall back

land balanced

after you hit the serve you need to land balanced to facilitate your ability to recover to get ready for the next shot– the key to this is toss location — in front and slightly left or right
