Physical activity can be defined as anything from biking to work to cleaning your pad, while actual exercise is activity done with a purpose — like hitting the gym or going for a run. While any sort of movement is better than being sedentary, it's important to note that if you really want to achieve any noticeable progress with your health and fitness goals, you have to do quite a bit more than read your favorite mag while walking on the treadmill (busted!). According to Barbara Robb, a contributing writer and health expert for Everyday Health, there are four major components you should include in your routine.
For starters, there's cardio-respiratory endurance. If you want to keep that ol' ticker of yours in tip-top shape, you've got to make sure you're constantly upping the ante through aerobic activities such as swimming, cross-country skiing, or even walking. Once you reach a set distance or intensity goal, gradually bump it up so that you're still feeling challenged. Aside from cardio, don't be afraid to lift weights (or jump on a machine) to increase your muscular strength, too. Who said keeping fit was supposed to be easy?
