What benefit is achieved through a combination of aerobic exercises and muscle-strengthening activities?

Engaging in a combination of aerobic exercises and muscle-strengthening activities primarily leads to reduced risk of heart disease. Aerobic exercises, such as walking, running, or cycling, support cardiovascular health by improving heart function, lowering blood pressure, and enhancing circulation. Muscle-strengthening activities, like weight lifting or resistance training, contribute to improved muscle mass, metabolic rate, and overall physical resilience. When these forms of exercise are combined, their synergistic effects promote better heart health, help manage body weight, and improve overall physical fitness, further lowering the risk factors associated with heart disease.

In contrast, options indicating increased stress levels, higher body fat percentage, or decreased bone health do not reflect the positive outcomes associated with regular physical activity. Instead, structured exercise routines are known to alleviate stress, promote a healthier body composition, and support better bone density through weight-bearing activities. Thus, the combination of aerobic and strength training activities is beneficial for overall health and significantly contributes to a lower risk of heart disease.
