Fit Grips Sport - Sphere Thickening / Fat Bar Training (Round Ball Shape)
Fit Grips Sport spheres are roughly the same size as a baseball. The sphere shape allows you to instantly increase the outside diameter of dumbbells, curl bars, resistance bands, pull-up bars, push-up bars and cable attachments for thick bar (fat) training.
Long-lasting, high-quality, dense, non-slip military grade silicone that resists extreme wear and tear. Fit Grips have a unique cross-stitch grip design that enables a safe and strong hold. Used by NFL players, MMA fighters, bodybuilders, cross-fitters, power-lifters and many pro athletes.
The ergonomic round design distributes force to the natural shape of the human grip. By increasing the size of the bar you will notice more isolation on your forearms, biceps and triceps.
The outside diameter is 2.5 inches. Inside diameter is 1 inch which fits on most standard and olympic bars.

Why Thick Bar Training? Try contracting just your bicep with an open hand. Then contract your bicep plus your forearm with a closed fist. You will notice a much stronger contraction in your bicep when your fist is closed. This is called muscle irradiation. The basic principle of irradiation states that the harder a muscle contracts, the harder the surrounding muscle contracts. This is the principle behind the movement to thicker training bars. If your hand is contracting more because the bar is thicker and awkward to control, the entire muscle group activated by the exercise will be more engaged. In the early days of bodybuilding, thick handle barbells were more common with 2 inches plus outside diameters. Today, most gyms and training centers are equipped with barbells and dumbbells with 1 inch handles. However, there is a resurgence in thick handle training equipment because trainers, athletes, bodybuilders and recreational lifters are re-discovering the significant benefits when the Fit Grips are used. Core Prodigy has several versions (round and cylinder) called Fit Grips. Fit Grips Sport (sphere with 2.5 inch O.D.).
