Which health condition is associated with inactivity?

High blood pressure, also known as hypertension, is closely associated with inactivity. Regular physical activity helps maintain a healthy weight, strengthens the heart, and improves circulation. These factors contribute to lower blood pressure levels. In contrast, a sedentary lifestyle can lead to weight gain, increased stress on the cardiovascular system, and a higher risk of developing various chronic conditions, including hypertension.

The other options highlight the benefits of physical activity rather than conditions associated with inactivity. Improved muscular strength, higher flexibility, and enhanced agility are all positive outcomes that result from engaging in regular exercise, illustrating the contrast between active and inactive lifestyles. Thus, high blood pressure is the condition that aligns with the consequences of a lack of physical activity.
