While we have all seen the athlete flipping a dirty old tire back and forth to get their fitness on, we had a different idea. We took a five-foot by thirty-inch by twenty-four-inch piece of foam and made a space to add weight in the middle. Then we wrapped it in a denier cover and added straps. Now all the adaptive athletes get to flip the Coffin, get fit, and drag heavy weight around for all the fun fitness.
