Product detailed description

12 levels of resistance adjustment, from 12 to 82 kg!

Everyone, regardless of age or gender, can take care of their health with just one booster from the GD brand.

2x resistance level settings

Iron Grip's resistance now starts from 12 kg, which can be held by anyone, regardless of age or gender, up to 82 kg, designed for demanding people. A more detailed setting is possible in 12 steps.

Two types of handle

1. Aluminum knurled handle
this handle is designed for real athletes with many years of experience in sports. Provides training with a stable grip.
2. Silicone handle
soft but firm non-slip handle. It was created for those who lacked grip because the knurling was too harsh. It can be used for a long time without deformation, even without tape.

I already knew GD grip trainers are among the best on the market, so this time I decided to properly test the Iron Grip 12. It’s excellent. Once I reach 82 kg, I will definitely buy the Grip 90 model. I would appreciate if you continue developing and selling high-quality products not only for grip strength but for overall upper body strength. I will gladly buy them. I am very satisfied...

A big difference compared to cheap grip trainers. Both quality and design are very good. Since it looks nice, it makes you want to use it more and train more often.

I previously used an older Iron Grip which I sold second-hand, and now I bought this new 12-level version. It’s great. The silicone grip feels comfortable and thanks to 12 levels, resistance can be adjusted precisely depending on the situation. If you are hesitating, I definitely recommend it...

The adjustment is more detailed, so it’s great that both parents can use it together.

Good, but handles can be better. Got the silicone version and it feels pretty cheap, The handle is mostly a hollow plastic sleeve that fits over the steel frame, with a nut inside for the bolt. It probably won't break at 80kg (max) but they really could've used a higher quality plastic and silicone because this thing is expensive, my 10$ chinese gripper feels more premium. The aluminium one is probably more sturdy, but it can be too harsh on hands according to reviews, for that one you can use tennis tape or something similar and you get a metal handle at least, instead of a cheap plastic one. Why is the silicone more expensive than the aluminium one, only they know. Also you get 5 years of warranty but you have to pay the shipping costs. However the main body is indeed high quality metal and steel, i ll keep it for the adjustable resistance and handle positions. The mechanism itself will most likely outlast the plastic handles.
