The importance of getting regular exercise is probably nothing new to you. The health benefits are well known and established: regular physical activity can produce long-term health benefits by reducing your risk of many health problems, such as heart disease, cancer, and diabetes, and it can also increase your chances of living longer, help you control your weight, and even help you sleep better.

As a busy college student, you may be thinking, “I know this, but I don’t have time! I have classes and work and a full life!” What you may not know is that precisely because you have such a demanding, possibly stressful schedule, now is the perfect time to make exercise a regular part of your life. Getting into an effective exercise routine now will not only make it easier to build healthy habits that you can take with you into your life after college, but it can actually help you be a more successful student, too. As you’ll see in the section on brain health below, exercise is a powerful tool for improving one’s mental health and memory—both of which are especially important when you’re in school.

The good news is that most people can improve their health and quality of life through a modest increase in daily activity. You don’t have to join a gym, spend a lot of money, or even do the same activity every time—just going for a walk or choosing to take the stairs (instead of the elevator) can make a difference. The following video describes how much activity you need:

Physical Fitness and Types of Exercise

Physical fitness is a state of well-being that gives you sufficient energy to perform daily physical activities without getting overly tired or winded. It also means being in good enough shape to handle unexpected emergencies involving physical demands—that is, if someone said, “Run for your life!” or if you had to rush over and prevent a child from falling, you’d be able to do it.

There are many forms of exercise—dancing, rock climbing, walking, jogging, yoga, bike riding, you name it—that can help you become physically fit. The major types are described below.

Aerobic Exercise

Aerobic exercise increases your heart rate, works your muscles, and raises your breathing rate. For most people, it’s best to aim for a total of about thirty minutes a day, four or five days a week. If you haven’t been very active recently, you can start out with five or ten minutes a day and work up to more time each week. Or, split up your activity for the day: try a brisk ten-minute walk after each meal. If you are trying to lose weight, you may want to exercise more than thirty minutes a day. The following are some examples of aerobic exercise:

• a brisk walk (outside or inside on a treadmill)
• dancing
• a low-impact aerobics class
• swimming or water aerobic exercises
• ice-skating or roller-skating
• playing tennis
• riding a stationary bicycle indoors.Strength Training

Strength training, done several times a week, helps build strong bones and muscles and makes everyday chores like carrying heavy backpacks (or grocery bags) easier. When you have more muscle mass, you burn more calories, even at rest. Here are some ways to do it:

• Join a class to do strength training with weights, elastic bands, or plastic tubes (if your college has a gym, take advantage of it!)
• Lift light weights at home

Flexibility Exercises

Flexibility exercises, also called stretching, help keep your joints flexible and reduce your risk of injury during other activities. Gentle stretching for 5 to 10 minutes helps your body warm up and get ready for aerobic activities such as walking or swimming. Check to see if your college offers yoga, stretching, and/or pilates classes, and give one a try.

Being Active throughout the Day

In addition to formal exercise, there are many opportunities to be active throughout the day. Being active helps burns calories. The more you move around, the more energy you will have. The following strategies can help you increase your activity level:

• walk instead of drive whenever possible
• take the stairs instead of the elevator
• work in the garden, rake leaves, or do some housecleaning every day
• park at the far end of the campus lot and walk to class.
