Larry Gallagher created an adjustable, stable box nearly five feet tall to challenge even the mightiest of CrossFit’s leapers.
Sometime last fall after a workout at San Francisco CrossFit, I was pulled aside by Kelly Starrett. He had a vision of creating the ultimate jumping box, a platform that would be stable and high—higher than anything anyone at SFCF had ever ascended. Confident in my modest but solid woodworking skills, I accepted the challenge.
After a few weeks of head-scratching and sketching followed by a day of cutting, gluing and screwing, I was able to present him with the prototype adjustable jumping box. In the long-standing American tradition of semi-literacy, we dubbed it “Kelly’s Koffin.”
The Koffin has quickly worked its way into the culture at SFCF. Coach Adrian (Boz) Bozman has added a Koffin T-shirt to his line of homemade silkscreens and has also offered a challenge to all CrossFitters: mount the box at the highest setting (58 inches) and receive a free T. Thus far only two SFCF athletes have achieved this distinction.
Do you have what it takes? Planning a trip to the Bay Area soon? The Koffin beckons.
