If you spend hours at a desk or driving, you probably have tight hips. This tightness can significantly impact your running performance, affecting both your form and speed.
The more time you spend sitting the more contracted your iliopsoas—the strongest group of muscles in the hip flexors—becomes. As these muscles shorten, your stride may also shorten, disrupting your natural gait. This imbalance can lead to other muscles overcompensating to stabilize your body, increasing the risk of injury.
