How do you find time for physical activity when you're busy?

It's important to plan ahead, list "to-do" items to avoid unnecessary activities taking up exercise time. Prioritize exercise by:
Schedule: Schedule physical activity like all appointments for the day. Try not to let other activities interrupt or change your exercise plan. Join a sports team: Organize a soccer or volleyball team with other members at the parks and locality where you were born. This is a great incentive to stay active. Join a fitness club: Sign up for an exercise class at a nearby club or gym. Expenses can also be an incentive for you to stick with your workout schedule. Wear an activity tracker or pedometer: Knowing how far you've walked, or how many calories you've burned, can motivate you to be more active.

To avoid wasting time at home, you can make exercise a priority at home by:
Wake up early : Get up a little earlier than usual for a walk on the treadmill or a brisk walk around the neighborhood. Housework: Mop the floor, scrub the toilet, or do other household chores at a fast enough pace to get the heart pumping. Gardening: Mowing the lawn with a pusher is a great way to burn calories. Rakes and hoes help strengthen the arms and back, and digging will help the arm and leg muscles work better. Get active while watching TV: Use dumbbells, stationary bikes, or do stretches while watching your favorite shows. Walk to the TV to change channels or adjust the volume instead of using the remote. Do more errands: When you get to the mall, park your car away from the entrance and walk an extra distance. If you have time, go for a walk 1-2 laps before you start shopping. Always bring a pair of walking shoes to get you ready for a busy person's workout in a few minutes.

To be more physically active while you are at work, you can:
Make the most of your commute: Walk or cycle to work. If you take the bus, get off a few stops early and walk the rest of the way. Take the stairs whenever possible: If you have to move to another floor, get off the elevator a few floors early and use the stairs. Better yet, take the stairs entirely. Exercise during breaks: Instead of lounging around in the lobby with coffee or snacks, take a short walk. Limit texting: If it's convenient, walk to a co-worker face-to-face instead of texting or emailing. Always be physically active: If you're traveling for work, plan ahead. Bring a sports band or choose a hotel with exercise equipment. If you're stuck at the airport because of a flight delay, pack your bags and walk around. Here are general guidelines for how to find time when you're too busy to exercise. But to fit your day's schedule, it's important to be flexible and make fitness a way of life. There's no need for a stereotypical exercise plan, because all physical activity counts as exercise for busy people, making you stronger.
