Many swimmers try to improve their freestyle by focusing only on technique, but the real limitation is often mobility. In this guide, Coach Dan Daly explains how shoulder mobility, hip rotation, and thoracic spine mobility work together to create a smoother, more efficient stroke. You'll learn why proper freestyle body rotation matters, how movement restrictions affect your technique, and what simple dryland exercises can help you move better in the water. Whether you're a competitive swimmer, triathlete, or Masters swimmer, improving mobility can make your freestyle feel stronger, lighter, and more connected.
