Don't Let Your Friends See This Device!

I used the device to build and test my strength to prove the haters 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.
