For your heart's sake, regular physical activity is just as important as controlling blood pressure, maintaining an acceptable cholesterol level, or stopping smoking. The research also shows that you don't have to be a marathon runner or mountain climber to reap the benefits. Do it as you brush your teeth, watch T.V., or wait for water to boil. Make housework a part of your plan. Dust, vacuum, and wash windows regularly.
Outside work helps, too.
Depending on the season, you can push a wheelbarrow, rake leaves, chop wood, shovel snow. Walk to school, the store, the mailbox, the park. Climb stairs instead of taking the elevator. Include active hobbies in your leisure time. Dance vigorously and often.
