The de­vice comes from phys­i­cal ther­apy, to help mus­cles heal

Elec­tronic ab stim­u­la­tors How they work:

A wide belt, wired to a bat­tery, is worn around the waist. The mus­cles are then stim­u­lated with tiny elec­tri­cal shocks at timed in­ter­vals, de­signed to make them con­tract.

What are the ben­e­fits?

Man­u­fac­tur­ers say that wear­ing the belt for 30 min­utes a day will give you stronger, firmer and more toned ab­dom­i­nal mus­cles, and will re­duce the size of your waist.

What the ex­perts say:

The de­vice comes from phys­i­cal ther­apy, where it’s used to help in­jured mus­cles heal. But Cedric Bryant, chief sci­ence of­fi­cer of the Amer­i­can Coun­cil on Ex­er­cise, says what works on dam­aged mus­cles will have min­i­mal ef­fects at most on healthy ones, adding that the only way to achieve vis­i­ble abs is to lose belly fat. Mean­while, Quist says the amount of stim­u­la­tion needed to tone mus­cles with the de­vices would be so great that it’s likely you’d burn or in­jure your­self in the process. There’s also a risk that the ma­chines could in­ter­fere with im­planted de­vices like pace­mak­ers.
