I've earned Candidate for Master of Sport in kettlebell half marathon. I'm the first American man to earn CMS from the International Kettlebell Marathon Federation.
I did 309 jerks with a 28k bell in 30 minutes. This is 19,158 pounds of work, or almost ten tons of lifting and supporting in 30 minutes. Heart rate probably in the 160's-170's throughout the set. Strength and conditioning in one session!
