Abs for Life: Runner's Core Training Plan
Why do runners need core exercises?
Your core muscles (chest, back, abs and obliques) are what keep your torso upright when you run, and reduce "wobbling" when moving your arms and legs. Core strength allows the pelvis, hips and lower back to work together more smoothly to expend less energy.
This training plan is designed to help you focus on your core for better stability, form and overall running fitness.
You can also use this plan to help you create defined abs and to come back from injury to ensure your body is ready for running.
Always seek the advice of a professional to ensure you are performing the exercises correctly and in a safe manor.
