Final answer:
Moderate-intensity exercise is best for cardiovascular health and stress reduction.
Step-by-step explanation:
Research has shown that moderate-intensity exercise is best for cardiovascular health and stress reduction. Aerobic exercises, such as cycling, walking, and running, increase cardiovascular health. Regular exercise has been shown to reduce stress and protect against stress-related health problems. Anaerobic exercises, such as weight training, are more effective for building muscle mass. Flexibility exercises improve the range of motion of muscles and joints, reducing the risk of injury.
