Running is essentially a series of one-legged hops repeated over and over again. The repetitive nature of running can exacerbate imbalances in any part of our body.  While many mild asymmetries are normal and not necessarily cause for concern, others can make you more injury prone.   This week’s guest helps runners deal with all types of imbalances. Dr. Sarah Ceschin is a physical therapist from Boulder, Colorado, who I had the pleasure of meeting in person at a recent group run. Sarah works with a variety of athletes, particularly runners and climbers.  If you ever find yourself in need of a physical therapist, try to seek out one who is familiar with treating runners! As a runner herself, Sarah understands the demands of running and helps runners stay healthy and strong. As a physical therapist, she deals with athlete imbalances on a daily basis and is a tremendous resource to learn how to address them. In our discussion, we dive deep into the topic of asymmetries and imbalances, including: How to define an imbalance, and where you may find unexpected imbalances in your body Why some imbalances are normal and shouldn’t make you worry How more pronounced imbalances may increase your risk of overuse injuries  The unexpected asymmetries you may discover in trail running How fatigue accentuates imbalances: picture mile 26 of a marathon!
