How strong is your upper back?
In CrossFit, we do lots of squatting, lower body pulling, pressing, and pull-ups. There’s not much in the way of upper body pulling, though, and this can create an imbalance that can lead to shoulder and back dysfunction. We are adding in more upper body pulling variety. If you’re not able to attend classes where we pull, try to add some different pulling movements in to your accessory work.
