Product Description
At 2 inches in diameter, the SIDEWINDER PRO XTREME IS THE ONLY FOREARM ROLLER TO PROVIDE THICK GRIP TRAINING WITHOUT A WEIGHT PLATE.

Strengthen your hands, wrist and forearms in one compact package. Made in the USA, all Sidewinder models are meticulously manufactured by hand! SideWinders including the PRO XTREME are made of solid, industrial parts including steel tubing, machined aluminum and neoprene handles. Unlike cheaper, competitor products, they contain no plastic parts that can wear down and crack apart.

You control the resistance by turning the built-in calibrated tension gauge. When winding the handles, twist them with one hand or both. Alternate hands after each set using both clockwise and counterclockwise motions. All SideWinders twist smoothly and quietly in any resistance setting.

The PRO XTREME is double the weight of the mid-level Pro model (#2 roller). And you can set the resistance down to easy or to the highest level that’s truly hardcore. To give you an idea how hardcore, the Pro XTREME contains a tension spring spec. of 380 lbs. and roller bearings that can support 2000 pounds! We’re talking about machine parts that are used in manufacturing plants.

Comes with explanations of the grips and exercises you can do with your SideWinder. (Also includes free handy magnetic exercise chart only with Pro XTREME orders.)
