Core and Hip Stability For Runners & Triathletes

TT position

Getting to the “Core” of the matter is essential to be a durable, faster, injury free athlete.


As endurance athletes we put in many long hours training for our goal events and one of the biggest concerns is that an injury will pop up or linger impacting our ability to compete. How do most injuries happen? The simple answer is, muscle imbalances! Where do most of these muscle imbalances originate? Our body’s core, which is comprised of many central muscles including transversus abdominus, multifidus, the diaphragm and the pelvic floor. The core muscles provide your spinal and central muscle systems with stability and also coordinate movement to your extremities. Without a strong core, we will not be able to keep the body standing or moving in the correct aligned position which will put the spine, arms and legs out of position and in a vulnerable stability pattern for movement and the possibility of injury.  A muscle imbalance, which is undetectable with the naked eye, can become a more serious problem causing another muscle group to compensate and leading to injury over time. Injury prevention is not the only benefit of a strong core, it also creates the right pathways for the muscles to fire in the correct patterns and improved core strength and proper muscle firing patterns produce faster training and racing times. One of the biggest benefits to your training and racing will be that the stronger your core, the longer you can hold proper technique and form. Below are a listing of some of the ideal core and hip stability exercises that every endurance athlete should incorporate into their training at least twice a week for a faster, injury free racing season and beyond. Remember while executing these exercises to remain tall, shoulder down and back, pull your belly button towards your spin and tuck your tailbone under you.
