This muscle stimulation / toning kit was bought for a younger relative who is "into" keeping fit as a Christmas present as he is difficult to buy for. I'd heard of these devices which use electrical pulses to cause rapid contraction of the muscles which acts as a sort of workout to keep them toned. I think it's doubtful that using these alone without any sort of exercise regime will give you a 6 pack as it won't turn a coach potato into a Mr Universe but for someone already weight training and exercising I think it will help.
The kit comes in a box and you get:-
3 x Rechargeable Controller Units
1 x Large Abdominal Pad
2 x Body Pads
1 x USB Charging Cable
1 x Instruction Manual
10 x Extra Gel Pads
The abdominal and body pads stick to the part of the body you want to give a "workout" to using the gel pad which also provides a good electrical contact to the body. The control unit is fastened to the pad by two metal press studs and has 3 x control buttons which lets you choose which one out of x 6 "workout" modes to choose and what intensity of "workout" between 1 to 10 to use.
Each control unit has a micro USB port for charging from a mains powered USB plug, a phone charger, a power bank or the USB port on a laptop or games console. As for the pads, it's best to put the plastic cover on the gel parts when not in use as it will ensure they will continue to allow the pad to continue to stick to the body and sure a good contact. When they eventually lose their adhesiveness simple remove and use one of the extra gel pads which are provided in this kit.
I cannot yet comment on the efficacy of this muscle stimulation / toner kit as it won't be getting used til after Christmas but I'm sure my nephew will be happy with this aid to his fitness programme.
