Balance exercise is one of the four types of exercise along with strength, endurance and flexibility. Ideally, all four types of exercise would be included in a healthy workout routine and AHA provides easy-to-follow guidelines for endurance and strength-training in its Recommendations for Physical Activity in Adults.

They don't all need to be done every day, but variety helps keep the body fit and healthy, and makes exercise interesting. You can do a variety of exercises to keep the body fit and healthy and to keep your physical activity routine exciting. Many different types of exercises can improve strength, endurance, flexibility, and balance. For example, practicing yoga can improve your balance, strength, and flexibility. A lot of lower-body strength-training exercises also will improve your balance.

Having good balance is important for many activities we do every day, such as walking and going up and down the stairs. Exercises that improve balance can help prevent falls, a common problem in older adults and stroke patients. They can also benefit those who are obese since weight is not always carried or distributed evenly throughout the body. A loss of balance can occur when standing or moving suddenly. Often we are not fully aware that we may have weak balance until we try balance exercises.

How much do I need?

Balance exercises can be done every day or as many days as you like and as often as you like. Preferably, older adults at risk of falls should do balance training 3 or more days a week and do standardized exercises from a program demonstrated to reduce falls. It's not known whether different combinations of type, amount, or frequency of activity can reduce falls to a greater degree. If you think you might be at risk of falling, talk to your doctor.

Tai chi exercises also may help prevent falls. Balance, strength and flexibility exercises can be combined.

Try these balance exercises:

See how long you can stand on one foot, or try holding for 10 seconds on each side.

Walk heel to toe for 20 steps. Steady yourself with a wall if you need a little extra support.

Walk normally in as straight a line as you can.

If you find standing on one foot very challenging at first, try this progression to improve your balance:

Hold on to a wall or sturdy chair with both hands to support yourself.

Next, hold on with only one hand.

Then support yourself with only one finger.

When you are steady on your feet, try balancing with no support at all.

Examples of balance exercises:

You can do balance exercises anytime or anywhere.

Try standing on one foot while working in the kitchen, waiting in line or brushing your teeth.

Walk heel to toe around the house or office.

Yoga and Tai Chi do not require expensive classes or equipment. Find an instructional book, DVD or website to get started at home. Local recreation centers and senior centers may also offer free or low-cost classes.

What if I'm recovering from a cardiac event or stroke?

Some people are afraid to exercise after a heart attack. But regular physical activity can help reduce your chances of having another heart attack.

The AHA published a statement in 2014 that doctors should prescribe exercise to stroke patients since there is strong evidence that physical activity and exercise after stroke can improve cardiovascular fitness, walking ability and upper arm strength.

If you've had a heart attack or stroke, talk with your doctor before starting any exercise to be sure you're following a safe, effective physical activity program.

There are two good reasons to turn your workout into a balancing act. First, a controlled wobble activates deep core muscles to help tighten the midsection. Secondly, it prepares athletes for that quick turn or lunge.

Before each move in this workout, engage your abdominals by tightening them-without holding your breath-as if preparing to take a punch. You'll activate the core muscles surrounding your spine and tone your entire abdominal area. Engaged abs also help prevent injury when lifting.

If you have a medical condition, be sure to check with your doctor before trying this workout or any new fitness program.

1. One-Legged Balance

Start with this beginner's move, keeping a stable chair or a wall within an arm's reach. With feet together, pick up one foot with the knee facing forward or to the side. Hold the position with eyes open, then closed. Switch feet and repeat for four reps on each foot.

If any move feels wrong or unsafe to you, stop and check with a trainer. Depending on your health and physical condition, some exercises may not be recommended.

2. Leg Swings

Stand on your right leg and raise the left leg three to six inches off the floor. With arms at your sides, swing your left leg forward and backward, touching the floor for balance, while keeping your torso erect. Now, repeat the moves, but don't allow your foot to touch the ground. And finally, swing the left foot to the left side, holding the right arm out. Switch legs and repeat.

3. One-Legged Clock With Arms

Balance on one leg, with the torso straight, head up and hands on the hips. Visualize a clock and point your arm straight overhead to 12, then to the side at three, and then circle low and around to nine without losing your balance.

Increase the challenge by having a partner call out the different times to you. Switch to the opposite arm and leg and repeat.

We often hear about the physical benefits of exercise (e.g., increasing heart health), less often are the psychological benefits promoted. Yet, engaging in a moderate amount of physical activity will result in improved mood and emotional states. Exercise can promote psychological well-being as well as improve quality of life.

The following are common psychological benefits gained through exercise.

Improved mood

Reduced stress as well as an improved ability to cope with stress

Improved self-esteem

Pride in physical accomplishments

Increased satisfaction with oneself

Improved body image

Increased feelings of energy

Improved in confidence in your physical abilities

Decreased symptoms associated with depression

As people experience these psychological benefits, it is likely that they also will be motivated to continue exercises so that they continue to receive these benefits. How much exercise is needed to produce those effects?

Even a brief walk at low intensity can improve mood and increase energy. As little as 10 minutes of aerobic exercise can have a positive effect.

For long-term benefits, you should exercise 3 times a week for 30 minutes per session at a moderate intensity.

Programs longer than 10 weeks work best for reducing symptoms of depression

According to the experts, there are many social benefits of physical activity for teens. Everyone knows the health benefits, such as weight control, lowered blood pressure and improved cardiovascular health, and because of that, the social benefits tend to take a back seat.

The Social Benefits of Physical Activity for Teens

When it comes to keeping fit, some teens want to know what's in it for them. While many teenagers will exercise for the physical value, not all teenagers enjoy sports or working out. These teenagers might appreciate knowing they can reap other advantages from exercise, especially those which will help them socially.

Related Articles

Exercise Improves Self-Image

Even if their friends and family think they look fine, teens often have a very poor self-image. Physical activity helps with more than just weight control, clothes size and muscle tone. As the authors at Helpguide.org suggest, when exercise becomes a way of life, it can bolster a flagging sense of self-worth and make a teenager feel strong and health-conscious. In fact, NPR reports researchers found there was a clear and defined link between organized sports and happiness.

Exercise Increases Self-Esteem and Confidence

As Mentalheath.net explains, self-esteem refers to a person's ideas about her worth and importance to others. It is hard to be comfortable in a group or to stand your ground socially if you are struggling with doubts about your value. Self-esteem and self-confidence can sometimes be elusive emotions. However, Psychology Today, referencing several studies, reports that physical activity has a profoundly positive effect on both self-esteem and confidence.

Exercise Reduces Stress and Anxiety

These days, teens are more stressed than ever with so many demands on their time and so much pressure from different sources. It is difficult to feel particularly social when weighed down by stress. However, almost any exercise can help reduce stress. Any physical activity will release endorphins, the brain's natural feel-good chemical, which results in a great, natural sense of well-being. Author Kirsten Weir writes about what the American Psychological Association (APA) terms the "Exercise Effect" and reports that Scientist Jasper Smits from the Southern Methodist University in Dallas has suggested that the byproducts of exercise, such as increased heart rate and sweat production, are similar to what the body undergoes when subjected to anxiety. Smits reasons that if exercise helps regulate these systems as part of a consistent regime, they should stay regulated even during times of heightened anxiety.

Exercise Helps You Make Friends

Many forms of physical activity can be helpful for teens looking to meet new people. If their preferred physical activity is organized sports, the team aspect may bring teenagers many new friends. Yet, even if teenagers are participating in an individual activity, such as rollerblading or hiking, there may be other teens out there to share the experience with. The National Alliance for Youth Sports (NAYS) credits the friendships made through sports as being some of the most unique and meaningful.

Exercise Improves Academic Skills

A lesser-known benefit of regular exercise is the claim that it might just make you smarter. When studies are going well and grades are improving, teens have more time to engage with their peers and enjoy an eclectic social life. There is a strong link between physical activity and academic performance at school. Researchers from the UK who analyzed a sample of five thousand children found that a moderate to high level of exercise correlated favorably with better academic performance and exam results.

Teamwork and Cooperation

It may seem obvious, but sports and games, as Play For Change points out, have the power to increase children and teenagers' social skills including the ability to cooperate with others, work as a team, and problem solve. Most team sports teach leadership skills as well as team building skills. This high level of cooperation fosters great communication skills and allows young people to develop confidence in their ability to interact with others.

Exercise Deters Depression

Even though socializing and exercise might be the last things on your mind when you are feeling down, it seems that physical activity can be a powerful deterrent to sadness and depression. This is also part of what the APA terms the "exercise effect," referenced above. Not only does exercise improve your mood almost immediately, but studies have shown that it can help to alleviate long-term depression too.

Exercise Helps You Sleep

Lack of sleep makes a person irritable and disinclined to socialize. The Centers for Disease Control and Prevention (CDC) publishes guidelines for how much sleep a person should optimally have, dependent on age. It suggests that teenagers should aim for eight to ten hours a night. However, some teens, even when they have the time to achieve this, are finding sleep hard to come by. Anxiety over exams, friends and extracurricular activities (to name but a few issues) are preventing many teenagers from gaining the sleep they need. The National Sleep Foundation points out that studies suggest moderate exercise reduces the time it takes for a person to fall asleep, as well as increases the time during which a person stays sleeping.

Exercise Is an Alternative to Negative Behavior

Behaviors such as autism and ADHD might be a deterrent to a teen's ability to fit well into a group of peers. Healthline reports that issues such as ADHD seem to be increasing and most parents and teenagers would like to know there were alternatives to drugs for those affected. Luckily, a recent study reported by CBS News reveals that exercise can eliminate some of the behavioral issues demonstrated by children with ADHD and even autism. Daniel Coury MD points out that the endorphins and dopamine released during exercise improve the brain's overall functioning powers.

What Type of Physical Activity Should Teens Be Engaging In?

Some types of sports, games, or exercises may be more appealing to teenagers. Just about any type of physical activity is beneficial. While team sports do more easily foster friendships, it is important for a teenager to pick an exercise that he or she likes. Studies suggest that only one in three children are active each day. If a teenager finds a sport or exercise he or she enjoys, it is more likely that the teen will retain the habit and keep exercising throughout his or her life. Fortunately for those with busy schedules, the Guardian reports that exercising once or twice at the weekend is almost as good for your health as exercising more often throughout the week.

Moderate Physical Activity

Walking two miles

Swimming laps for twenty minutes

Cycling four miles

Vigorous Physical Activity

Dancing for thirty minutes

Playing Tennis for thirty minutes

Playing a game of soccer, football, or basketball for thirty minutes

Check out the National Heart, Lung and Blood Institute's Guide to Physical Activity for some sometimes surprising ideas about other activities which might work for you.

How Can Physical Activity Benefit Your Social Health?

Hopefully, teenagers will see that they do not have to be fanatics to reap the benefits, both social and physical, of keeping active. Even exercising once a week is useful. The advantages of keeping fit are widely documented and there are so many sports and activities teenagers can choose from to achieve their personal goals. Exercise should be a choice for the mentally conscious as well as the physically conscious. It is a crucial part of a well balanced life.

Your blueprint for developing a healthy exercise routine

You already know that benefits come when you prioritize physical fitness. The trick is understanding what, exactly, "fitness" is and how you can go about achieving it.

That's where the five components of fitness come in. They are the blueprint for the American College of Sports Medicine's (ACSM's) physical activity guidelines and serve as a helpful tool for organizing and executing your own well-balanced workout routine.﻿﻿

The five components of fitness are:

Cardiovascular endurance

Muscular strength

Muscular endurance

Flexibility

Body composition

Creating a fitness plan that incorporates each of these elements can help ensure that you get the most health benefits from your routine.

The Centers for Disease Control and Prevention (CDC) links regular physical activity to a reduced risk of cardiovascular disease, type 2 diabetes, some cancers, improved bone health, enhanced mental health, and improved quality of life with age.

Cardiovascular Endurance

Cardiovascular endurance (also known as cardiorespiratory endurance or aerobic fitness) refers to your body's ability to efficiently and effectively intake oxygen and deliver it to your body's tissues by way of the heart, lungs, arteries, vessels, and veins. By engaging in regular exercise that challenges your heart and lungs, you can:

Maintain or even improve the efficient delivery and uptake of oxygen to your body's systems

Enhance cellular metabolism

Ease the physical challenges of everyday life

Given that heart disease accounts for roughly 630,000 deaths in the United States each year, starting a workout program that enhances cardiovascular fitness is of particular importance. Running, walking, cycling, swimming, dancing, circuit training, and boxing are just a few of the many workouts designed to benefit heart health.

The ACSM's physical activity guidelines call for at least 150 minutes of moderate-intensity exercise each week, or 75 minutes of vigorous exercise.

The key, of course, is consistency. It may sound like a lot, but 150 minutes breaks down to just 20 to 30 minutes of exercise per day, five to seven days a week, depending on how hard you push yourself.

Muscular Endurance

Muscular endurance is one of two factors that contribute to overall muscular health. Think of muscular endurance as a particular muscle group's ability to continuously contract against a given resistance.

Long-distance cyclists offer a clear example. To continuously pedal a bike over a long distance, often up steep inclines, cyclists have to develop fatigue-resistant muscles in their legs and glutes. These are evidence of a high level of muscular endurance.

Likewise, holding a plank to develop core strength is another example of muscular endurance. The longer you're able to contract your abdominals and hold your body in a steady position, the greater endurance you have through your hips, abdominals, and shoulders.

The extent to which you choose to focus on muscular endurance should be directly related to your own health or fitness goals. It's important to realize that muscular endurance is muscle group-specific.

This means you can develop high levels of endurance in some muscle groups (like cyclists building endurance in their legs) without necessarily developing the same level of endurance in other muscle groups, depending on your needs.

For Everyday Health

For general health purposes, you may want to develop enough endurance to simply climb up several flights of stairs or to lift and carry groceries from your car to your house. Low-intensity weight-bearing or strength-training workouts will help you build up that endurance.

For Fitness-Related Goals

But if you want to become an endurance athlete capable of competing in sports that require continual muscle contraction, such as obstacle course races, CrossFit, or cycling, you may want to place a higher focus on training regimens that use high-repetition strength training and sport-specific activity to make you a better athlete.

Muscular Strength

While muscular endurance refers to how fatigue-resistant a particular muscle group is, muscular strength refers to the amount of force a particular muscle group can produce in one, all-out effort. In strength training terms, it's your one-rep max.

Like muscular endurance, muscular strength is muscle group-specific. In other words, you may have incredibly strong glutes, but comparatively weak deltoids; or incredibly strong pectoral muscles, but comparatively weak hamstrings. This is why a well-balanced strength training program that targets all of your major muscle groups is so important.

Consider Your Goals

The extent to which you train for strength is, again, determined by your own health and fitness goals. For instance, if your focus is on health, you know you should be strong enough to lift a heavy box or to easily stand up from a chair. In this circumstance, enhanced muscular strength may be a byproduct of a workout routine focused more on developing muscular endurance.

If, however, you want to develop muscle mass or to be able to lift heavier weights at the gym, your training regimen should be focused more on lifting heavy weights.

To Improve Muscle Strength

To Improve Muscular Endurance

It's possible to improve muscular strength and endurance at the same time. This can be done in conjunction with cardiovascular training. For instance, circuit-training routines that combine strength exercises and cardio into a single bout of training can make your exercise program more efficient.

The ACSM's guidelines state that adults should perform strength training exercises two to three days a week using a variety of exercises and equipment to target all the major muscle groups.

Flexibility

Flexibility refers to the range of motion you have around a given joint. Like muscular strength and endurance, flexibility is joint-specific. For instance, you may have very flexible shoulders, but tight and inflexible hamstrings or hips.

Flexibility is important at any age. It plays a role in unhindered movement and can affect your balance, coordination, and agility. Maintaining a full range of motion through your major joints can reduce the likelihood of injury and enhance athletic performance.

As you get older, the importance of flexibility becomes even clearer. Think of individuals who are elderly: Many may walk with a shuffle or have a hard time reaching their arms over their heads.

This may affect their quality of life, making it more challenging to perform activities of daily living, such as reaching items on high shelves, picking up items off the floor, or simply moving effectively to catch their balance if they start to fall.

While completely stopping the aging process isn't possible, protecting your joints and maintaining mobility can help keep you spry well into your later years.

The ACSM's physical activity guidelines call for adults to engage in flexibility exercises at least two or three days each week.

How to Increase Flexibility

There are simple ways you can work flexibility exercises into your day:

Static stretching, where you hold a stretch for 10 to 30 seconds at a time

Workouts that take you through dynamic stretching exercises, such as barre, yoga, Tai Chi, or Pilates

Active stretching, such as lifting your leg up high and holding it there, uses the contraction of the opposing muscle to relax the muscle being stretched.

Passive stretching, also called relaxed stretching, where you assume a stretch position and hold it with assistance of another part of your body, a partner, or apparatus, like a strap.

Isometric stretching, a type of static stretching, uses resistance to alternate between relaxing and contracting the muscle.

Body Composition

Body composition, or your body's ratio of fat mass to fat-free mass, is the final component of health-related physical fitness. Because high levels of fat mass are associated with negative health outcomes, such as heart disease and type 2 diabetes, attaining and maintaining a healthy body composition is a goal of just about all regular exercise routines.

Measuring Body Composition

To see improvements in body composition, you need to know what your starting point is. Weighing yourself on a scale won't do the trick, as weight alone tells you nothing about the makeup of your internal tissues.

Instead, talk to a trainer about having your body fat percentage tested, or consider purchasing a scale that uses bioelectrical impedance analysis (BIA) to estimate body fat percentage.

Hydrostatic testing is currently the gold-standard of measuring body composition. It involved being weighed on dry land followed by sitting on an underwater scale. The greater the fat composition, the lighter the underwater weight will be.

DEXA (dual-energy X-ray absorptiometry) scans, typically used for measuring bone mineral density and assessing for osteoporosis, can also be used to accurately measure body composition. DEXA scans are usually performed at radiology centers and may or may not be covered by insurance.

Though not as accurate as a DEXA scan or hydrostatic testing, you can also take your own measurements and plug them into a body fat percentage calculator. The results are estimates that typically fall within three to four percentage points of your actual body fat percentage, so it's important not to get too hung up on the specific numbers.

Use results from body fat percentage calculators as a barometer to monitor changes and make sure you're seeing improvements over time.

Improving Body Composition

The good news is, improved body composition is often an outcome of working on and improving the other four components of fitness. If you're regularly hitting the gym, doing cardio, strength training, and working on flexibility, chances are you're developing muscle mass (fat-free mass) while reducing fat mass.

These three exercises are considered examples of anaerobic exercises.

Isometric exercise: refers to exercises that allow the muscles to contract and become stronger over time. There is usually no movement: these exercises are stationary.

Isotonic exercise: refers to contracting and relaxing muscles in a series of often repeated exercises. This is a little more movement through the joints of the body.

Isokinetic exercise: kinetics means movement, so this type of exercise has a lot more movement than the other two. Exercises allow the muscles to contract at a constant rate and are often used in therapy to rebuild muscle strength after an injury through resistance training.
