**Special shout-out… Happy Birthday, Dallas!**

Here is the final installation in the CrossFit 603 “Big Ups” series. As some background… we traveled from Sacramento to San Francisco CrossFit with our friends Matt and Donna of MaD CrossFit to meet Adrian Bozman (Coach Boz) and take the Koffin’s lunch money. When we arrived, Boz told us the creator of the Koffin – Larry Gallagher himself – was on site building some plyo boxes. How. Cool. Is. That?

The Koffin is essentially two big boxes, the top of which slides down over the bottom. They’ve built peg holes into both pieces, with brackets that slide into the holes from the outside. You raise and lower the top to adjust the height, and hold it in place with the brackets. At its highest, the Koffin measures 58″… just shy of 5 feet. It’s… tall. And until we got there, only four people in the whole world had managed conquer its highest setting. (The requirements of “conquering” the Koffin are simple – jump from the ground, land with both feet on the box and stand all the way up at the top. They don’t care if you run, skip or pas de bourrée your way up to the thing – just get UP there.)

I don’t want to give anything away, so I’ll let you watch the video to see how it all transpired. A big thank you to Coach Boz and San Francisco CrossFit for their hospitality, and to Larry Gallagher for some damn fine craftsmanship.
