I bought the waver vibration plate for my parents. My dad had knee surgery years ago and had lost a lot of mobility in his knee. They both have been using it twice a day and my Dads knee swelling has gone down so much that you can tell just by looking at it and no more knee pain.
I bought this vibration plate to help with muscle strengthening and overall toning. It uses oscillation vibration, which activates the legs, glutes, and core. It also improves circulation and boost muscle activation without stressing your joints, this is a solid choice.
