On Saturday, Nick Anapolsky, the seven-year CrossFit athlete set a new chest-to-ground burpee world record by completing a staggering 879 reps in one hour at Polskys Strength & Conditioning and CrossFit PSC, a CrossFit box in Kitchener, Ontario, CA that Polsky owns. If you’re trying to do the math, that’s just under 15 burpees per minute for the entire hour.
