well Jayz, starting off, we need to know the correct grip, do you know what grip is used mainly in the single-handed backhand?
if you don't, i'll explain how to hold it correctly, picture this, you are holding the racquet by its handle, and you turn you hand so that the index knuckle is aligned to the top of the grip, do you see how the grip is like a hexagon shaped sorta thing? well it should be aligned to the very top of the grip, thats called a classic backhand grip.
that grip is used mainly in conventional singlebackhands.
when you strike the ball, hit the ball with a down to up motion, but you need to hit through the ball, dont push it, hit through it,
once you get the feeling, it'll be easier for you.
best of luck!
