Line of Action in the Air Squat

At a CrossFit Level 1 Certificate Course, a participant demonstrates the air squat. Staff member Austin Malleolo focuses on her line of action, which is the relationship between the hip and the knee in the squat.

“The reason that’s important is because, as we get going with speed and load, that can start to pull us forward, weight off the heels, it can lead to a whole cacophony of errors,” Malleolo says.
