The promise of the Flex Belt is both intriguing and enticing. The system promises to allow anyone to tone their abdominal muscles while doing just about anything else, anywhere including lounging on the couch, sitting at work, or even sleeping. This lazy multitasking is obviously appealing, but unfortunately, is largely grounded in wishful thinking.
The Flex Belt serves to capitalize on a common misunderstanding about abdominals. The misunderstanding is based on the relationship between abdominal strength, which is measured by the size of the muscle, and the percentage of body fat, (BF%). Body fat is found between the muscles and skin. By wearing the belt 30 minutes a day, the Flex Belt is supposed to stimulate the muscles enough to flatten the stomach. However, these contractions are not as effective as old-fashioned crunches.
This is in part due to the common misunderstanding that fat can be turned into muscle. But if that was true, then you have 3 inches of fat between your ab muscles and your skin, you would get abdominal muscles about 3 inches thick. Even bodybuilders, with their intense training programs and extreme diets, are seldom able to achieve an abdominal muscle, or even a bicep, that is 3 inches thick. It’s just not how human beings are designed. It certainly cannot be achieved with zero effort like the Flex Belt would have you believe. EMS contractions are simply not strong enough to achieve this.
The EMS (Electronic Muscle Stimulation) effect would have no impact on a person’s BF%, so the only conceivable benefit of the system would be towards the strength of the underlying muscle.
The actual, effective path to toned abs is paved with work and dietary consideration. The simple equation of calorie intake versus calorie output is the primary guideline to follow to see real and rapid results. If you output more energy than you take in from food, your body will be forced to power the difference by metabolizing fat.
Lastly, the promotion of “cleared by the FDA” is misleading. FDA clearance constitutes a recognition of safety, not effectiveness. So while you won’t likely harm yourself using this device, you will also not see any major benefits

A second band should be passed around the upperportion of the pelvis, and held by an assistant, to guard againstdrawing the body from its position by the action of the pulleys.A wetted napkin or roller is then to be firmly applied around thethigh immediately above the knee, over which a leathern band isto be buckled, having attached two short straps with rings atright angles with the circular part and directly opposite eachther. Instead of the straps and leathern belt we may substituteo pieces of new muslin, each four inches wide and about twoeet long, by laying them one upon the inner and the other uponle outer aspect of the lower part of the thigh, so that the mid-Qe of each may be confined by passing a wetted roller tightlybround them; the upper extremities are then to be reflectedownward and tied with the corresponding ends below; the loopshus formed are to be fastened to the hook communicating withbe staple in front of the patient.

Fig. 278. After considerable tension has been produced by traction uponthe cord, the efforts of the assistants are to be discontinued for afew moments in order to fatigue the muscles more easily, at thesame time exercising care not to diminish the degree of extensionalready produced. In this manner the succeeding efforts are tobe intermitted, the surgeon in the meantime watching closely theposition of the trochanter major and the head of the femur byplacing his hand upon these prominences. Provided the head ofthe bone does not readily resume its natural position upon reach-ing the margin of the acetabulum, the surgeon should seize thethigh and gently rotate
