In front of a chalkboard for a discussion on exercise theory, Coach Greg Glassman suggests midline stability isn’t just about safety. It’s also about performance.
Think of the midline as your “transmission”: a solid midline allows you to transfer force efficiently, while a weak midline results in lost force, decreased power and inefficient movement. Keeping your core tight is absolutely critical if you want to achieve elite performances in CrossFit WODs.
“The wiggle in this midline is energy expended for which it is not a productive application of force, and it equals slower Fran time,” Coach explains.
