Running can have both positive and negative effects on joint health. On one hand, it strengthens the muscles surrounding joints, providing better support. It also promotes optimal bone density and cardiovascular health. However, excessive running or poor form may lead to joint degeneration over time. It is essential to incorporate rest days, cross-training, and strengthening exercises to minimize injury risk. Proper footwear and running surfaces can further protect joint health. Balance, moderation, and attention to form can help runners enjoy the benefits while minimizing adverse effects.
