Your right starch, you wouldn’t want that to happen. What most people don’t realize is, that the pads have to be placed directly on the muscle motor points. If they aren’t, you can do some real damage. Back in the eigthies when the Tens units were brought to the publics attention, everyone and their uncle thought they were going to purchase one and perform miracles on them selves.A lot of people got hurt.The FDA stepped in and took control of the sale and use of them. At that point only trained medical people were allowed to operate them.There was one gal who came in and was supposed to have been trained(licenced nurse), she started “BOUNCING” this old guy all over the table, he was screaming like a banshee! He was actually getting shocked through out his body. The Tens units are operated by three large nine volt battery.Placing them on the muscle motor points causes the muscle to involuntary contract and then relax.The time of contraction and relaxation is adjusted by the attending operator, nurse or doctor. The results are very amazing, especially for someone who has just finished or is on a active diet.Three inch or more loss is amazing and very measurable.The machine will only exercise the muscles it is attached to.It will strengthen and tone that particular muscle.Placed around the waist, you would see a loss of 4-5” after five or six treatments.The lasting time depending on if the person continued a active diet or exercise program or went home and started pigging out again.Yes, I did play around with the machines and the best you could expect was to feel the beginning of a organism, women mostly.Had two state body builders that use to come in before a tournament to get pumped, one you might know.So for those that say that it doesn’t work, please tell me your experience and length of time you were involved with the Tens units.
