Instead of isolated muscle movement using conventional commercial gym equipment, I believe in functional fitness. Functional fitness exercises train your muscles to work together and prepare them for daily tasks by simulating common movements you might do at home, at work or in sports. While using various muscles in the upper and lower body at the same time, functional fitness exercises also emphasize core stability. For example, a squat is a functional exercise because it trains the muscles used when you rise up and down from a chair or pick up low objects. By training your muscles to work the way they do in everyday tasks, you prepare your body to perform well in a variety of common situations.
