Understanding Tennis

you can use two hands on the backhand volley

expand the court with a short angle

on return  combat And block to survive the big serve

on the  forehand rotation keep the other hand on the racquet helps compact the stroke

try and use your feet and move through the volley using your whole body to volley

get the toss in front and leap in

jump to bring the ball into a lower hit zone 

on the two handed backhand get both elbows up

on the slice set your angle early and leave the angle throughout the hit

when you arc the bend should be a straight line

get the back knee blow the in coming shot

on the fist serve Monfils  brings his feet together on the second  serve he keeps his feet apart

get the hit in front and square up

when the lob goes up spin out to get in position to hit the overhead

get into the air–to bring the ball into a lower hit zone
