Cost: The cost of exercising can be the time and effort required to incorporate it into your daily routine. It may require dedicating a specific amount of time each day to engage in physical activity, which means altering your schedule and making room for it.
Benefit: One of the main benefits of exercising is improved physical health. Regular exercise helps strengthen your muscles and bones, improves cardiovascular health, boosts the immune system, and can lead to lower risks of chronic diseases such as obesity, heart disease, and diabetes. Exercise also releases endorphins, which can improve mood and reduce stress levels. Additionally, exercising regularly can help with weight management and enhance overall energy levels.
