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.
Shake Weights were found to be pretty useless in the past, but BodyVib’s weights could change that: they vibrate 2160 times per minute, which is 10 times faster than traditional ones.
