For those who would like to exercise a little but can’t find the time to workout, BodyVib created these design weights to cut your training in half.
The dumbbells vibrate at 36Hz (or 2 160 vibrations/min) with an amplitude of 1.2mm, which is apparently more than enough to ‘intensify’ your workout by up to 50%.
The idea behind the vibrations is that it causes the muscles in your hands and arms to quickly contract and relax in response, burning more energy in a shorter period of time, and resulting in a longer afterburn time.
The weights need to charge for 30 to 50 minutes, and will the vibrate for up to 2 1/2 hours, using a sensor to only start the vibration motor once you grab the handle. The price however is quite high available in 3.3, 6 and 10 pound pairs for a whopping 649 £ (about 743 €) to 729 £ (about 835 €).
