Butt kicks do more than just stretch your quads, they help prepare them to stay strong and active throughout your run. This drill targets the front of the thigh, which plays a key role in knee lift and running speed. Quads often fatigue late in long races, making it harder to lift your feet and maintain form. Butt kicks help keep these muscles flexible, engaged, and ready to power you through the finish line, without the shuffle! Watch on YouTube.
