I used this to see if I can generate over 60kg of grip strength

I used the device to build and test my strength to prove them wrong! If you also want to do the same, you can get the Alfagrip here: https://futuresolace.com/products/alfagrip%E2%84%A2

This grip trainer is specifically designed to increase your grip strength, build a vascular and strong forearm and track your progress in an easy-to-understand user interface.
It was built with durability in mind! The materials used are premium quality and are ideal for handling your full strength! So don’t hold back and squeeze with all you’ve got!
