Attach to any pull based gym machine, hang, or lift. Crimp training is a specialized training technique primarily used to improve grip strength, finger strength, and overall upper body power functionally. This method involves using a crimp block or hangboard. The main objectives include increasing the ability to hold onto small holds, and forearm flexor strength. This can also help reduce the risk of injury by conditioning the fingers, hands, and forearms. This block has a 25mm crimp for beginners, a 20mm crimp for general training once your used to the pulling motion, and a 5mm edge for advanced grip athletes aka micro edge training.
