Issues with Backhand and forehand

Hi,

i have this problem because I want to get my arm to my eyebrow for the forehand topspin so then my strokes are too vertical my coach has told me to shoot through the ball but I'm unable to stop myself from playing vertically is there any way I can get my forehand  to hit through and not up. 

Thnks

Hi,

By rotating your waist forward you are also getting the forward movement of the bat.  This combined with the upward movement of the arm will give you a good balance of the stroke.  You can also get your arm to finish a little in front of your eyebrow for the faster balls.  Think of a ruler sticking out from your head and finish at the end of the ruler.
