STANDARD CORE SEQUENCE
These moves work your abs as well as your hips, glutes, lower back and hamstrings – all the muscles that help you maintain proper running form even when you’re fatigued. ‘ I always seem to get hurt when I get lazy and stop doing this routine consistently,’ says Fitzgerald. Do each exercise for 45 seconds. Go through all the moves twice; it will take about nine minutes. After a few weeks, increase to one minute for each exercise.
