Why is it that gymnasts never have to do a bicep curl to get big and strong biceps? How about weightlifters… you may not know it, but they NEVER do leg extensions, leg curls, leg press, or adduction/abduction exercises. Weight machines were designed by engineers to simulate the isolated movement of one muscle in your body. In real life, your body rarely uses one muscle at a time independently of all others. So while you may be getting bigger biceps, you are functionally less strong.
At CrossFit LA, you’ll NEVER do a bicep curl or a leg extension. We choose exercises that make large demands on your nervous and muscular systems and require many muscle groups to work together synergistically. Body weight exercises challenge you to be strong and agile enough to be in control of your body (pull ups, dips, handstand push ups, push ups, etc). Weightlifting exercises require technique and skill, and call upon a large number of muscles in your body to work together at the same time (squat, deadlift, clean, jerk, snatch, kettle bell, etc).
