I was just wondering for all you big smashers out there. Whenever I try for a full power smash, I tend to like flex my biceps? I don't really know how to describe it, but I squeeze something. However, I've been reading that having tensed muscles is not good for being able to accelerate the racket. To clarify, its not the forearm that I'm squeezing, but the area around the bicep right before I swing, and i feel like it is actually giving me more power. Am I doing it wrong? Would it be a bad thing to do? Just wanting to ask the badminton masters h ere.
