What Our Gearhead(R) Experts Are Saying:"I set this up in my garage over the winter to keep my jamming sharp between trips to the desert. Being able to dial in the exact width for hand jams versus fist jams made a noticeable difference once I got back on real granite."Crack climbing rewards a very specific kind of practice, and the Wide Boyz Crack Trainer brings that practice home instead of leaving it for the next road trip. We adjust the two halves to match a hand jam, work through a few reps, then widen it out for fist stacks, building the exact movements a real crack pitch will ask for. The Soft Grip surface keeps sessions comfortable enough to log real training volume, and multiple units can link together into full boulder problems when one crack width isn't enough. It's a setup built for the unglamorous repetition that turns into confidence on an actual splitter.
