The Pro Xtreme is the thickest, heaviest, longest and the most powerful model of the Sidewinder line. The thick handles will force you to engage muscles you wouldn't normally use which will lead to super-strength and injury prevention.
The combination of constant tension, exaggerated range of motion, single/double hand usage, and multiple hand positions makes the SideWinder Pro Xtreme an essential tool for anyone pursuing larger, well-developed forearms. Changing your grip lets you target different muscles - strengthening your biceps, triceps, and shoulders while you work your forearms.
Many have recommended using the Sidewinder Pro Xtreme in addition to training with hand grippers and fat grip barbell adaptors. This combination trains your crushing and twist-isometric grip.
No rope and weight plate required. Set the resistance that's perfect for you - from easy to hardcore. To control the resistance, just turn the built-in calibrated tension dial.
When winding the handles, twist with one hand or both, using both clockwise and counterclockwise motions. This works the extensors and flexors. The SideWinder twists smoothly and quietly, so you can use it on the couch or in the office. No DIY wrist roller can do all of this.
The SideWinder is meticulously manufactured by hand. Made of industrial steel and neoprene rubber. Contains no parts that can degrade and crack.
