5-60KG Sport Hand Grip Trainer | With Adjustable Counter
Hand grippers are a great multi-purpose grip training tool. It is convenient to
use while you are on the go, at your desk or in your vehicle when stuck in
traffic, or even simply in your home. Hand grippers can help you improve the strength of your crush grip as well as strengthen grip strength, and help build the forearm muscles.
Primax Projects' Hand Grip Trainer is equipped with an adjustable counter device with a minimum resistance of 5kg, completely designed for beginners or younger customers to utilise. 
What's the function of the device that counts the handle? The counter device that is
located on the handle tracks each rep you do. It counts up to 100 reps before resetting. To do a full rep, both handles must fully connect, clicking the counter. This will increase the rep number on the device. To reset the reps, turn the adjustable counter until it's back at 00.
