Single Leg Half Squat - Running is a series of jumps from one leg to another. There is never a time when both feet are on the ground at the same time (unless the hill is very steep or you are very tired - AKA walking). Additionally, each time you land, one leg needs to absorb multiple times your body weight at impact. So, small deviations in your biomechanical alignment can add up to big performance losses and even pain. Pay close attention to your form and use a mirror to monitor your alignment. When you can do these movements well, every step will be more predictable, more powerful, more accurate, and will propel you further with less chance of soft tissue strain.
