Exercise and physical activity fall into four basic categories—strength, endurance, flexibility, and balance. Many focus on one activity or type of exercise but it is far better to incorporate 2 or more of these categories into your training regimen. This way you are balancing the body out, and that helps prevent injuries and speeds fitness progress. That means RESULTS!!!
The great thing is some of these categories accomplish more than there intended result. For example many strength training exercises also help to improve your balance. while many endurance activities strengthen the muscle.
