I'm a 60 year old man and use my ems suit every other day on a high intensity setting, and it's absolutely amazing. I've lost 60 lbs in 18 months and routinely get compliments.
The woman speaking is right on the money. This workout device is one third of the equation. The calories you take in is the second third, and effective rest or sleep is the third. This could very well work as a work out device but you must eat enough of the right calories and also must have effective ram sleep for you to burn fat.
