Topic Overview

Aerobic activity raises your heart rate and keeps it up for a while. This increases the amount of oxygen delivered to your heart and muscles. Over time, this kind of activity benefits your heart, your muscles, your mood and self-esteem, and your amount of energy. It can lower your blood pressure, cholesterol, blood sugar, body fat, anxiety and depression, and fatigue.

Finding the right activity

Experts say to do regular moderate activity and/or vigorous-intensity activity.

Here are some ideas for both types of activities. You can boost many of the moderate activities in the left column to a vigorous level by doing them faster or harder.^footnote1

Moderate intensity	Vigorous intensity
General exercise: Brisk walking Light to moderate calisthenics (for example, home exercises, back exercises, getting up and down from the floor) Low-impact aerobic dancing Jogging on a small trampoline Weight lifting, body building, using a lot of effort Light to moderate workouts on gym equipment like Nautilus or Universal machines or a rowing machine	General exercise: Walking uphill, jogging or running Heavy calisthenics (push-ups, sit-ups, jumping jacks, etc.) High impact aerobic dancing Jumping rope Using a stair-climber or skiing machine Stationary bicycling, with vigorous effort
Water exercises: Treading water with moderate effort Water aerobics or water calisthenics Kayaking, canoeing, white-water rafting Springboard or platform diving Paddle boating	Water exercises: Swimming laps with fast, vigorous effort Treading water with fast, vigorous effort Water jogging Rowing a canoe in competition Skin diving and scuba diving
Outdoor activities: Fishing and hunting Playing with a Frisbee Children’s games, like hopscotch, 4-square, and dodge ball Playing on playground equipment Downhill skiing Shovelling snow	Outdoor activities: Horseback riding—trotting or galloping Competitive sports like rugby, field hockey, and soccer Hiking with a backpack Mountain biking Ice skating quickly (more than 15 kph) Snowshoeing and cross-country skiing
House and garden work: Sweeping, vacuuming, and mopping floors Washing the car with vigorous effort Sweeping the garage, sidewalk, or patio Washing the dog Mowing or raking the lawn Digging in the garden	House and garden work: Carrying groceries upstairs Carrying boxes or furniture Baling hay or cleaning the barn with vigorous effort

Adding variety to a fitness program is a good way to keep motivated.

• Vary the activity. If you are getting bored with walking, try swimming or an aerobics class.
• Vary the place. Try a new route for walking or biking or even a different room for your exercises or stretching. By having several options, you can pick one that suits your mood or schedule.
• Vary the time. Do your exercises at different times and for different amounts of time. If you become bored with your noon walk, try exercising in the early morning or after work or school. Instead of doing one 45-minute session, do three 15-minute sessions.

Activity at the office

If your job includes lots of sitting, try adding these short bursts of activity to your day:

• Use your commute to do some extra walking. Park several blocks away, or get off the bus a few stops early.
• Use the stairs instead of the elevator, at least for a few floors.
• Suggest holding meetings with colleagues during a walk inside or outside the building.
• Go the extra distance when possible: Get your coffee on another floor (use the stairs) or use the washroom that’s the farthest from your office.
• If you need to speak to a co-worker, walk to that person’s office or station rather than using e-mail or the phone.
• Use your morning and afternoon breaks to take quick 15-minute walks.

Coaching and teaching

If you are bored with a sport or activity that you once enjoyed, coaching or giving instruction can renew your interest.

• Youth leagues for organized sports are often seeking good coaches.
• Take classes to become a certified fitness leader.
• If you cycle, offer to lead a group of schoolchildren on a bike ride to teach bicycle safety.
• Offer to lead a walking group.
