AI-Generated Deep Dive Summary
Running isn’t just about logging miles or hitting the pavement hard—it’s also about building a strong foundation, starting from the core. While many runners focus on visible six-pack abs, true core strength lies deeper than surface-level muscle definition. According to experts like Holly Dickinson, a UESCA-certified run coach and NSCA-certified strength and conditioning specialist, developing a runner’s core involves functional exercises that stabilize your body during training and racing, rather than just isolating ab muscles through repetitive crunches.
Kristine Kearns, associate health and fitness editor at Runner’s World, shares her journey of discovering the importance of functional core workouts. She highlights the benefits of moves like dead bugs, glute bridges, and plank variations, which target the entire torso to improve stability and performance on the trails. These exercises are more effective than traditional sit-ups for building the kind of strength that supports your running form, breathing, and overall efficiency.
The article emphasizes that strengthening the core doesn’t require hours in the gym or grueling workouts. By incorporating functional moves into your routine just a few times a week, you can enhance your running performance and reduce the risk of injury. Runner’s World offers comprehensive programs like their *Guide to Strength Training* and *Race-Ready Strength*, which provide structured workouts for both beginners and advanced runners. These programs focus on building a strong, resilient core that translates directly to better race results.
For those chasing personal bests, there’s also a progressive four-week plan designed to seamlessly integrate strength training into your race prep. By prioritizing functional core exercises, you’ll not only become a more efficient runner but also build confidence in your ability to tackle longer distances with improved form and stamina. Whether you’re new to strength training or looking to refine your routine, these programs offer the tools to unlock your full running potential.
In summary, ditching the crunches and embracing functional core exercises can transform your running game. By focusing on stability, strength, and efficiency, you’ll achieve better performance and long-term success in your fitness journey.
