In general, most modern lifestyles create shortened positions and weak lower ankles. Stability and strength of the lower ankle complex is vital for athletic performance as well as simply achieving a optimal walking gait. We must practice standing, walking, running more to keep a piece of prehistoric talents so we don’t become hunched over Simpsons characters. Use a TRX for support, start early on standing in front of a higher bench—and put a air ex pad for a booster chair if you need it. Single leg squatting to depth takes time and repetitive practice. Meaning, if you have never done a single leg squat, starting on the BOSU will result in a fall. Work up to it. THE ENTIRE FOOT REMAINS on the ground or surface. I do these after heavy, bilateral lifts to prevent fatigue and tightness the days following hard training bouts.
