To improve aerobic fitness, running is often considered one of the best exercises. It engages multiple muscle groups, enhances cardiovascular health, and boosts endurance when performed consistently. Running can be tailored to individual fitness levels, ranging from walking to sprinting, making it accessible for various age groups and backgrounds. Not only does it improve aerobic capacity, but it also releases endorphins, contributing to better mental health. Incorporating interval training or longer distances can further enhance aerobic benefits, making running a versatile and effective exercise for overall fitness.
