Physical fitness comes from a combination of regular exercise and a healthy diet. Think of this like you would your car. If you don’t drive your vehicle very often, and you put dirty fuel in it, how well will it run? So from a diet perspective, avoiding junk food, fast food, soft drinks, bad habits like alcohol and smoking, and getting a proper amount of rest – and eating whole, fresh, healthy foods in moderate quantities, is like putting clean fuel in your car. And, getting outdoors, going to the gym, or working out in your own home gym, is similar to driving your car on a regular basis. It keeps the fuel from clogging up the lines, keeps the battery charged, and allows you to notice when you need maintenance.
