The focus is on a unique variation of the arm jump technique, utilizing a crimp grip where reaching over the top is not possible. Instead, the technique involves using the tips of the fingers to create a secure landing position. This particular method emphasizes finger strength and engages the forearms more intensively than traditional grips, allowing for improved strength and stability during jumps.
In this adaptation of the arm jump, the depth of the crimp holds is only a couple of centimeters. This limited reach significantly alters how the arm jump is executed, demanding a different approach to landing. The technique is described as beneficial for enhancing finger strength, as it relies heavily on the use of the fingertips rather than the entire hand. The adjustment in grip enables climbers to manage their weight distribution effectively while jumping.
The crimp arm jump can be complemented by using the thumb in conjunction with the fingers, but only when the setup allows for it. Due to the specific dimensions of certain holds, climbers may need to adapt by focusing solely on fingertip engagement. Overall, this method can be quite effective and should be practiced whenever the opportunity arises in climbing situations.
Key Points:
- The crimp arm jump utilizes the fingertips rather than full hand grips to enhance finger strength and forearm engagement.
- The depth of crimp holds is crucial, as it alters the landing mechanics and weight distribution during jumps.
- While thumb engagement can enhance the grip, climbers should adapt their technique based on the specific dimensions of the holds available.
Demonstrate a standing arm-jump (aka Cat-Leap) from 6-steps (heel-to-toe) away, onto a chest-height or higher ridge, ledge, shallow edge or feature that only allows the first two phalanges (distal and intermediate) of your fingers to catch the wall.
Landing with knees bent, one leg higher than the other. One at hip-height, and underneath you. Landing feet first, then hands.
Arms must be bent on landing. Must be on the front edge corner of the wall.
Hold for 3 seconds.
Repeat three times.
Takeoff two feet from the jump. You cannot lean in without a jump into the arm-jump.
