Running often leads to tight hips, affecting stability. Four poses can help loosen them, according to Canadian Running. These poses target hip muscles, improving movement.

One pose involves sitting with legs wide apart, folding one leg forward and the other back. Hold for 30-60 seconds, then switch sides. Another pose is a seated wide-legged forward fold, stretching the back and hips. Read more culture coverage.

A third pose involves lying on the back, bringing one knee to the chest, and holding for 30-60 seconds. The final pose is a seated butterfly, stacking knees over each other for a deep stretch. These poses can be done individually or together. Related: German ultrarunner sets new women's record at Tor des Géants.
