I tried this 10-minute hip-strengthening routine and it improved my mobility and alignment

As a runner, I know how important strong, healthy hips are for my performance, yet I don’t think I’ve ever spent any considerable time training them. 

Good hip mobility is important for runners because it improves your stride, reduces your risk of injury and it generally keeps your running mechanics going in perfect order. Think of it this way, your hips are responsible for a huge range of motion in your body, so with good mobility in this area you’re going to have a much better running form.
