"Vibration platforms, which purportedly provide a host of bone, muscle, circulatory, flexibility and injury-rehab benefits by shaking your body 20 to 50 times a second as you stand on them, are becoming more varied and practical as the market grows beyond pro sports teams and physical therapy offices. Backed by numerous studies (sometimes company-supported) suggesting that vibration increases load and stimulation with less joint stress, the machines are promoted as “workout accelerators” that hammer muscles in half the time of normal gym sessions."
