Great forearm workout. Took me a few tries to figure the motion out but once there, its really easy. I only has it for 2 weeks so don’t know if it will make me as strong as Iron Fist but it’s definitely a good workout.
I needed something to give my wrist and forearm an easy workout at the office or while driving. This was a great filler to that. It has helped with grip strength, range of motion, and stability of hand flexors and forearm flexors.
This is a useful device for strengthening the wrists and forearms. As some other buyers already have noted, the instructions given on the package and in the product leaflet are not clearly translated into English, and some buyers will have difficulty with them. For anyone who is already familiar with exercise devices of this kind, the instructions are not an obstacle to using this product.
