BUILT FOR THE GOLFER WHO'S SERIOUS ABOUT BOTH HALVES OF THE GAME
If you're chasing more carry off the tee, we're going to make your body more powerful, more elastic, and faster to recover between rounds. If you're 55, 65, or 75 and just want to keep walking 18 without back pain or losing distance every season — that's exactly what these two machines were designed for. Most members come for one of those reasons. Most stay because they get both.

3.

Serena Williams, American former professional tennis player
On tour, playing back to back matches is tough on your body. Being ready the next day is the difference between winning or losing. If I can accelerate the recovery and healing process, I have a definite advantage. With my Power Plate, I have that advantage.
