With the GD Grip adjustable gripper, you can start at the level of resistance that's right for you and increase the resistance as your grip strength improves. Why limit your progress by using the same level of resistance day in and day out? Welcome to the future of grippers.
The resistance of the GD Iron Grip is generated by COMPRESSING a solid steel spring. Other adjustable grippers create resistance by STRETCHING the spring, which can be dangerous. Stretching a spring places extreme tension on the components holding the spring in place. These components often fail, resulting in dangerous flying debris and metal shrapnel. By compressing the spring, we've eliminated this risk altogether. Made in KOREA
Why buy SIX expensive grippers when you can have the same levels of resistance all in ONE grip strengthener? Better yet, you'll save 75% and end up with a higher-quality product that is more convenient and more comfortable to use. This is one of those rare moments when you can spend WAY less and get SO much more in return.
The GD Iron Grip completely silent operation allows you to strengthen your grip anywhere without detection. Since there is no need to worry about the annoying squeak sound that most grippers make, you can use your GD IRON Grip at work, on a plane, in a library, or even in a movie theater without bothering those around you.
