"I've been using the PPM mouthguard and I've seen some noticeable improvements in my balance, and a large improvement in the pain in my right shoulder while doing certain exercises.

The exercises where I've seen the most improvement so far are the shoulder press, lunges, step-ups and especially curls with a straight bar - this was the biggest difference because I wasn't able to do them before because of the pain in my shoulder."
