@bryanlongoria6: ECM (Expansion Compression model) is an experiment I’ve been testing out for myself, as it’s what we naturally do every second. From the cellular level in osmosis, to the organs in our body such as the lungs in inhalation and expiration. But for the biomechanics of the upper body too much expansion of the rib cage over time can build up to problems. Such as chronic rib flare or even lordosis (excessive arch) and will result injuries in connective tissues(ligaments), joint problems, and a reduction in mobility because of the habit of arching in all of your lifts, it can carry on to daily life. This can ultimately increase the stress environment in those connective tissues. A deep ROM isn’t optimally bad, buts it’s not worth the risk of an injury to get that deep “stretch” if you keep putting your joints and ligaments in that loaded position. #Fitness #gym #fyp #learnfromme #explorepage✨#godlovesyou
