The next couple of days are going to involve a lot of squats and C2B pull ups. And you are going to be judged. When your friend calls you out for a no rep, here are some friendly reminders why. We value integrity, quality, and measurability at MBS. Most of you do an awesome job of getting the job done the way the workout prescribes. But if we’re honest, it’s awfully tempting to short change movements at times. Especially in the heat of a competition moment. Rushing, panicking, and caring more about the score than the work will make fluid, full ROM movements questionable, if not blatant “no reps.” The Open is a chance to rise above and challenge yourself to hit every single rep right. Let’s commit to that as a community. Let people call you out. That’s why you are here and not at a globo gym. Friends don’t let friends squat above parallel.
Range of Motion (ROM)
Range of motion refers the distance a joint can be moved through. Full or functional ROM is the entirety of the distance a joint can move. For example, full ROM of the elbow is the distance allowed between your arm fully flexed where forearm touches bicep, and arm fully extended where elbow is completely straight.
Functional ROM
The CrossFit protocol is 1) constantly varied 2) functional movements 3) across broad time and modal domains. We like to think of functional as being a movement that can be applied “out there” in your everyday life. If you are a police officer and you only ever squat to half depth on the back squat, what is going to happen if you have to squat down to a deeper depth to pick a fallen comrade onto your shoulders? You are going to be in a pretty compromising situation if you haven’t trained squatting down low. The aim of CrossFit is to make you more functionally capable and that is only done through using our joints to their full or functional ROM.
ROM increases flexibility and work capacity
In addition to increased functional ability, working joints to their full ROM maintains flexibility. For members that spend the majority of their time at a desk, doing full-depth squats and pushups to the floor will maintain the flexibility of the hips and shoulders. For athletes that have old injuries that have led to decreased flexibility (the shoulder is a common one), working the joint to its fullest ROM will often increase the flexibility. Just ask any physical therapist what they do to recover patients from hip, shoulder, and knee surgery – they rehab with increasing ROM exercises!
