Mobility Vs Flexibility
/For the purpose of this post, we are going to define flexibility as the end range of motion a person can reach. For mobility, we’ll define it as the end range of motion a person reach while remaining stable throughout. For example, flexibility is the absolute lowest a person can squat while mobility is the lowest a person can squat while keeping their back flat, their knees out, and all that good stuff. Why does this matter? There is a spectrum from stability to mobility/flexibility. We would like to be balanced in the middle to stay healthy and prevent injuries. Simply put, if we are overly stable then that puts us at risk for muscular injuries, such as pulled muscles, tears, and strains. If we are overly flexible, that puts our joints at risk for ligament tears and sprains. How do we apply this to our training? A progression to stability and balanced mobility must begin with flexibility. We need to first gain the ability to go into a range of motion before we can go there while remaining stable. As a progression, certain stretches and mobility drills are only appropriate for people at a specific stage in the progression. For example, the forward fold is a stage in this progression. This stage involves an overly stable person who lacks the ability to touch his toes. That person’s next step is to gain flexibility in his hamstrings until he can touch his toes while being relaxed. Only after that should the person perform a forward fold with a flat back entirely through a hinge at the waist. If that person tried to maintain a flat back at the start, he would not receive much benefit from the stretch. He must first learn to get there before he can learn how to be stable there.
