The EverTone EMS Hips Trainer & Butt Toner uses Electrical Muscle Stimulation (EMS), a new scientific fitness technology that sends direct signals to your muscles to promote muscle movement. Designed for hip fitting, it stimulates the hip line effectively, releasing pressure and lifting your hip muscles. This trainer has 5 stimulation modes and 20 intensity grades to adapt to your needs. This device has shown positive results to improve and sculpt not only your butt but also your thighs. The EMS toner also works to relieve muscle pain, just like an electric massage causing muscles to rhythmically contract and relax.
