Which of the following is the primary factor for enhancing joint health?

Maintaining full range of motion is crucial for enhancing joint health because it ensures that joints operate within their natural anatomical limits. When joints move through their full range, it promotes the lubrication of the joint surfaces through synovial fluid, which reduces friction and wear. This fluid is vital for cartilage health, helping to nourish and prevent degeneration. Additionally, full range of motion exercises improve flexibility and muscle elasticity, which can help prevent injuries associated with tight muscles and stiff joints.

In contrast, while achieving greater muscle mass can provide some support to joints, it does not directly influence the health of the joint structures or improve their functional range. Improving cardiovascular endurance contributes to overall fitness but does not specifically target joint health. Developing core strength is beneficial for stabilizing the body, yet it does not address the mobility and flexibility needed for maintaining joint integrity. Therefore, emphasizing full range of motion is key to fostering joint health and function.
