Today, soccer is one of the most popular sports in the world. Championships and league cup events are some of the biggest social and athletic events of the year in many countries. This sport is also one of the most demanding athletically as it requires the use of almost every muscle in a player’s body at once. Playing soccer in a league or just for fun is a great way to receive a cardiovascular and aerobic workout. It can lower your body fat and increase flexibility and endurance. The health benefits of this sport are exponentially higher than some others due to the constant switching between walking, running, and sprinting which improves muscle tone and bolsters bone strength.
