Ever wonder why men have some strong sculpted arms? Perhaps it has to do with that dateless Saturday night activity that makes hair grow on your palms? Well now women too can tap into this masturbation exercise technique with the Shake Weight. The dumbbell that shakes back and forth and strangely mimics masturbation is supposedly based on “entirely new workout technology” called Dynamic Inertia, to shake your arms into shape. The Shake Weight also promises that it only takes 6 minutes per day (sounds about right…) and will tailor your arms into shape 300% better than traditional weights.
