The science is mixed but promising, particularly for improving strength, power, balance, and bone density. WBV may also help keep weight off once you've lost it. It seems to target the deep belly fat (visceral fat) that's linked to diabetes and heart disease. And in one small study, people with low back pain who vibrated twice a week for 12 weeks got relief.
So go ahead, "shake it up, baby," but check with your doctor first. There's not much known yet about side effects, but WBV is not recommended if you are pregnant, have a pacemaker, have a history of blood clots or seizures or have recently had a concussion
You might want to check with your banker, too. Vibrating machines are expensive.
