The Rhythm Slim combats muscle aches and slack skin through simple self-supplied muscular stimulation. $136
It might feel a little strange at first but you’ll soon notice the health benefits. Just try it every day for three minutes, and no batteries are required whatsoever. Just slip it under your chin and push down on the top piston, holding it down for ten seconds at a time.
Pushing the top part down will exercise your neck and jaw muscles, easing cramps and aches, and also fighting sagging skin and wrinkles.
