The GP3 is an ergonomic fitness device designed with a simple purpose - to make gripping exercise equipment easier. The contoured geometry of the outer layer naturally fits the shape of the palm and fingers during gripping activities. This allows for ultimate comfort and grip efficiency. A durable thermoplastic rubber with undulated, embedded grooves also provides a superior tactile feel to the user.In simplest terms: Sustaining a grip during exercise has never been easier, thanks to the GP3!
