"What Our Gearhead(R) Experts Are Saying:"I love how the Quad Block delivers targeted training for pinch holds. The grip sizes cover everything I need, and its aluminum finish makes my results consistent across sessions. It's a must-have for climbers pushing for stronger grip strength."The Lattice Quad Block elevates grip strength training with a portable and durable design. Featuring four distinct pinch sizes-deep wide, shallow wide, deep narrow, and shallow narrow-it targets key muscles in the forearms and hands for climbing-ready strength. The anodized aluminum finish provides consistent friction, ensuring repeatable results during testing and training. Combine it with the Lifting Pin and Fractional Weight Plates (sold separately) for incremental load adjustments, creating a versatile tool for climbers aiming to conquer every pinch hold.
