If you’re a runner looking to improve your performance and prevent injuries, there’s one thing you must be doing: strength training. At IMPACT Physical Therapy & Sports Recovery, we specialize in physical therapy for runners and see firsthand how crucial strength work is to staying healthy and keeping on pace. Many runners want to know the most important muscle for running and which strength exercises provide the biggest performance boost.
We asked our IMPACT physical therapists, “What’s the most important muscle to strengthen for runners?” While the entire kinetic chain matters, the most consistent answer was clear—your glutes. Strong glute muscles are essential for stabilizing your hips, controlling leg motion, and absorbing the impact forces that come with every stride. Research consistently shows that glute strength improves running efficiency and reduces injury risk, making it the top priority for most runners.
Weak glutes can contribute to a long list of common running injuries, including:
These injuries are some of the most searched problems among runners looking for injury prevention strategies.
Many runners skip the weight room, but strength training for runners is a game changer. Not only does it reduce injury risk, but it also improves:
You’ll run stronger and longer with fewer aches and pains. And don’t worry—proper strength training won’t bulk you up or slow you down. Consistent strength work helps runners maintain speed through training cycles and supports healthier biomechanics.
Looking to get started? Our physical therapists recommend these five foundational exercises:
These target your core, glutes, hips, and hamstrings—critical muscle groups for injury-free, powerful running. Strengthening these areas supports better running form and helps reduce overuse injuries seen in distance runners.
