$39 off Slendertone ARMS Muscle Training System

Enjoy firm and toned arms within four weeks with the Slendertone Flex Pro arms muscle training system. The easy-to-use upper arm toner employs Slendertone's patented Electronic Muscle Stimulation (EMS) technology to create strong, deep, comfortable contractions in your muscles.

EMS mimics the body's natural muscle movements by sending signals between the pads, engaging the nerves that control your muscles and causing them to contract naturally. As a result, you simply have to wear the system arms five times a week for four weeks to tone and strengthen your triceps and biceps without trudging to the gym on a regular basis.

The Slendertone ARMS Muscle Training System is equipped with three training programs (one each for conditioning, strength, and power), several gel pads, and a rechargeable handheld controller, the Flex Pro system can tone both arms at once using up to 99 intensity levels. There's no better way for your upper body to look its best. The Flex Pro training system fits upper arm sizes from 10 to 19.5 inches.
