CrossFit - The CrossFit Experience With Brian MacKenzie

Brian MacKenzie says endurance is a large part of CrossFit in this video filmed at the CrossFit Experience at the 2012 Reebok CrossFit Games. The founder of CrossFit Endurance has attendees practice drills to demonstrate how strength and conditioning is still important for muscle recruitment in endurance sports. Among those drills is simply hopping in place with good posture and then leaning to move forward while hopping. "What did they just do compared to what's taught in traditional running?" MacKenzie asks the crowd. "They utilized gravity. They were using gravity to their advantage." The drills, he adds, "get people to understand these things a lot quicker." MacKenzie also has participants jump rope with alternating feet so they can run while jumping rope. Such exercises will cement proper running form, he says. "We have to look at running as a skill," MacKenzie says. "It's the most destructive sport out there."
