Since the dawn of the competitive era in CrossFit, the leaders of the sport, and the leaders of the company have made some pretty bold claims. One of these claims was made in the past by Dave Castro, director of the CrossFit Games, who has gone on record as saying someone will one day be able to back squat 500lbs and then run a 5-minute mile, both in the same day.

Recently, multiple time Games competitor Austin Malleolo took that idea to extremes, in very impressive fashion. Malleolo PR'd his deadlift Monday morning, at a whopping 600lbs. Then, he proceeded to run, and complete, the Boston Marathon (26.2 miles) in 4 hours and 37 minutes.

This is a ridiculous demonstration of fitness, and something very, very, very few people could ever achieve. While it isn't the same movement or distance of Castro's bold claim, many would argue it is even more impressive. To have the raw strength to lift 600lbs off the ground, and simultaneously hold the muscular endurance needed to run 26.2 miles without stopping, speaks volumes about the effectiveness of CrossFit. Clearly, this proves that a well-trained* CrossFit athlete is not only incredibly fit, but exceptional across many different models and domains. 

Suck on that Jillian Michaels.

*just because someone walks into a CrossFit gym does not mean they will become well-trained. A well-trained athlete must follow programming from someone who knows what they are talking about and must have an incredible amount of individual drive. Don't get it twisted.
