Low-impact activities are ideal for protecting joints while supporting weight management goals. Water-based exercises like swimming and aquatic walking provide resistance without joint impact. Cycling, both stationary and outdoor, offers cardiovascular benefits with minimal joint stress. Walking on even surfaces, when progressed appropriately, builds strength and endurance. Tai chi, yoga, and Pilates improve mobility and stability. The key is matching exercise intensity to current joint capacity while gradually building strength and cardiovascular fitness. Strength training, when performed correctly, also helps stabilize joints.
