As if we don't have enough fitness items that vibrate, BodyVib has developed a set of dumbbells that vibrate at 2160 vibrations per minute. These battery-powered weights supposedly help you build muscle mass faster than traditional stationary dumbbells.
I can't attest to the claims of their muscle building prowess, but I will say this — you may want to work on your brain mass instead of your muscle mass if you even thinking about buying them. The BodyVib weights come in 1.5kg, 2.7kg and 4.5kg pairs and retail for a bewildering £649 ($965) to £729 ($1083). [Pro-Idee via Oh Gizmo]
