Staying firm and low while doing forehand loop

Hello, I've been playing table tennis for about two years. I'm having this problem when doing forehand loop drive that my body becomes upright after impact with the ball. Others have advised me to try to stay low and keep my upper body bent forward throughout my swing, but I can't seem to fix this bad habit.

 Another problem is that my swing seems too rigid and awkward. And the result is that my ball is always quite fast but very unstable. Can you recommend any exercises or tips that can make my swing a bit natural?

Thank you

Hi Heejoon,

One method to help with the stability and staying low is to get someone to hold something soft above your head while doing the stroke.  Something like a long soft stick.  This will give you some feedback when you feel the stick on your head.  Of course, make sure it is something soft!

To get your swing more free, start to focus only on how smooth your arm and body feel during the stroke.  Start by doing some swings without the ball.  As you are doing this feel how relaxed the muscles are.  Then as you swing in practice, feel each muscle that you are using and see how relaxed they are.  As you tune into this you will start to feel the smoothness in the stroke.
