3. Gather your equipment

You'll probably start with athletic shoes. Be sure to pick shoes made for the activity you have in mind. For example, running shoes weigh less than cross-training shoes, which offer more support.

If you're planning to buy exercise equipment, choose something that's practical, fun and easy to use. You may want to try out some types of equipment at a gym or fitness center before buying your own equipment.

Try using fitness apps for smart devices or other activity tracking devices. You can use them to track the distance you walk, track calories you burn or check your heart rate.
