Starting a fitness program may be one of the best things you can do for your health. Physical activity can lower your risk of chronic (慢性的) disease, improve your balance and coordination, help you lose weight, and even change your sleeping habits. It's easy to say that you'll exercise every day. But what you need at first is a plan. As you design your fitness program, here are five steps for you to get started.
Create a balanced routine.
The US Department of Health and Human Services (HHS) recommends getting at least 150 minutes of moderate aerobic (需氧的) activity or 75 minutes of vigorous aerobic activity a week, or a combination of moderate and vigorous aerobic activity. For example, try to get about 30 minutes of aerobic exercise on most days of the week.
Start low and progress slowly.
If you're just beginning to exercise, start carefully and progress slowly. If you have an injury or a medical condition, consult your doctor. You should design a fitness program that gradually improves your range of motion, strength and endurance.
Build activity into your daily routine.
Finding time to exercise can be a challenge. To make it easier, schedule time to exercise as you would do for any other appointment. Plan to watch your favorite show while walking on the treadmill, read while riding a stationary bike, or take a break to go for a walk at work.
Plan to include different activities.
Different activities (cross - training) can keep away from boredom. Cross - training using low - impact forms of activity, such as biking or water exercise, also reduces your chances of injuring or overusing one specific muscle or joint. Plan to alternate among activities that emphasize different parts of your body, such as walking, swimming and strength training.
Put it on paper.
A written plan may encourage you to stay on track.
Starting an exercise program is an important decision. But it doesn't have to be an overwhelming one. By planning carefully and pacing yourself, you can establish a healthy habit that lasts a lifetime.
