a) Joints become stiff and can easily become injured

1. Lack of exercise can cause:

a) Joints becoming stiff and prone to injury: When we don't exercise regularly, our joints may become stiff and less flexible. Without proper movement, the joint tissues may not receive the necessary nutrients and lubrication, which can increase the risk of injury.

b) Muscles becoming weak: Without exercise, our muscles can become weak and lose their tone and strength. Regular exercise helps in building and maintaining strong and healthy muscles.

c) Poor functioning of the heart and lungs: Exercise is essential for maintaining cardiovascular health. Regular physical activity strengthens the heart, improves blood circulation, and enhances lung function. Lack of exercise can lead to a weakened heart and reduced lung capacity.

d) Limited effect on fresh breath: Lack of exercise alone may have limited effects on breath freshness. Oral hygiene, diet, and other factors play a more significant role in breath odor. However, regular physical activity can contribute to improved overall health, which indirectly promotes fresh breath.
