When hitting a backhand shot, we need to use our wrist and we shouldn’t swing our arm fully. Besides that, the body rotation when doing a backhand is also important.
Not only that, your footwork also must be fast to complete a perfect backhand shot.
This might just shocked you. You might get muscle soreness because you are not using enough force when playing badminton. To avoid that, use more FORCE!
Besides that, we need to do some stretching to relax our muscle before playing badminton.
