Shake Weight

The Shake Weight - a revolutionary new women's arm-toning device unlike any product previously developed. Based on a groundbreaking workout technology called Dynamic Inertia, which engages the muscles in the arms, shoulders and chest in an entirely new fashion, the Shake Weight increases upper body muscle activity by more than 300% compared to traditional free weights.

Its distinct motion makes the Shake Weight the first product of its kind specifically designed to help women achieve toned, sculpted arms. Unlike the impression created by the rapid motion of the device, the Shake Weight is not battery-powered - the user generates the movement. The internal resistance and shaft bounces the weight back and forth, creating an effective workout that produces unparalleled results.

Shake Weight provides an entire upper body workout - shoulders, triceps, biceps and chest by engaging the muscles 300% more than traditional ABS.

Shake Weight comes with the "Upper Body Toning" DVD.
