Product: Flex Belt Cost: $199.99 Claim: Get strong, firm, toned abs in just 6 weeks
The Flex Belt, designed to be worn under clothing, delivers short pulses of electrical stimulation to the muscles and nerves in the abdominal area, prompting them to contract and relax. In as little as six weeks, the makers claim, the process will lead to leaner, toned abs. Yet not only is this device costly and its claim empty, especially if you have a lot of weight to lose, the Flex Belt may even be hazardous to your health. “Electrical currents may be unsafe for those with heart and other serious health conditions,” says Haley. For better results, she says, stick with the Bender Ball or try bodyweight exercises like the plank to slim and tone your core.
