Exercise is one of the core pillars of optimal health. It is an essential tool in your arsenal of lifestyle choices if you want to reduce or eliminate medication, improve your strength and flexibility or enjoy your everyday life with more energy and vitality.

It is relatively impossible to achieve optimal health without exercise. Your body was designed for movement and it's never too late to get started. No matter how old you are or how out of shape you think you've become, today is the day you can start to improve your future.

Of course, if you have an underlying medical condition, have an injury or haven't exercised in a long time, you'll want to seek medical advice from your physician.

You may also want to explore a wide variety of different types of exercise to maximize your health benefits. These include strength training, core training, burst training and cardiovascular work.

Most people think of just cardiovascular exercises when they consider a workout program, but strength, core and burst training are just as important to your overall health.

In the video below, Jill Rodriguez, personal trainer at Mercola.com demonstrates planks for beginners. But first let's talk about why core strength is important and how to make it fun.

Why Core Strength Is so Important

Core strength is so much more than strengthening your abs or having a flat stomach. Your core muscles, those around the middle of your body, are like a link in a chain of muscles.

If you've experienced back pain in the past, you know that movement in your arms or legs creates a ripple effect that's felt in your back as well. Almost any movement you make requires the activation of your core muscles.

This means your core muscles don't just include your abdominal muscles, but also those that cover your sides and your back. Pelvic muscles and even your hip muscles all work together to keep you upright, standing straight and pain-free.¹ These muscles work together to provide your spine stability and strength.

By definition, your spine is unstable. The small bones in your back allow your body to twist, turn and bend. However, without strong muscles to maintain an upright posture, this flexibility becomes a liability and not an asset. Acting almost like a corset, these muscles protect your back from injury and chronic pain.²

Weak core muscles will also weaken the actions of your arms and legs. No matter how much strength training you do to improve the power in your legs or the ability of your arms to lift, with a weak core foundation, you won't achieve your best results.

Functional Benefits of Core Strength

Taken separately, there are many different benefits to improving your core strength. Many of these fall under one of five different categories.

An Overall Test of Your Fitness and Why It's Important

Physical fitness and activity are important to both your overall health and prevention of several health conditions. There is a large body of evidence that much of the burden of ill health rests at the door of a sedentary lifestyle.⁸ This ill-health is both physical and mental.

Exercise and being physically fit reduces your stress level, improves your sleep, increases your energy level and reduces symptoms of anxiety and depression.⁹ All of these factors improve your self-esteem and make you feel proud of how you both look and feel about yourself.

While these factors are important to your mental health, exercise also has a significant impact on physical factors that play a role in your ability to perform your daily activities and in reducing your experience with pain and disease.

Being physically fit promotes maintenance of a healthy weight, which in turns reduces your risk for type 2 diabetes, certain cancers, cardiovascular disease and stroke.¹⁰ Other physical conditions affected positively by exercise include a reduced risk of osteoporosis.¹¹

One way to test your level of fitness is by using a plank test. If you can hold a standard abdominal plank, described below, for two minutes, then your overall physical fitness is off to a great start.

You may feel as if your current fitness level is not represented well if you can't hold the plank, but it could be your core strength is a problem and not your cardiovascular or extremity strength.

However, since core strength is so integral to your overall fitness, it's important you incorporate planks in your fitness routine. If physical fitness hasn't been a priority or you find it dull and boring, you may benefit from some ideas on how to make it fun.

Make It Fun

Sometimes you just need to make exercise fun in order to make it a habit in your life. Your first step is to stop negative self-talk, or the little voice in your head that repeatedly says, "I hate this!" The more you say it, the more likely it is you'll believe it. Find a partner you can exercise with a couple times a week. Look for someone motivated to making changes in their life and commit to each other to show up and share your results.

Set a challenge for yourself and a reward when you achieve it. For instance, when you can do a two-minute abdominal plank, you'll buy yourself a new MP3 player to listen to music while you're out walking. Music is an important motivator. Think about how some tunes make you just want to get up and dance and others can make you feel sad.

Choose music that energizes you and keeps you motivated to move forward. Music is also a great distraction when you're pushing to maintain your plank for those last 30 seconds.

Record your improvements as you progress. It can be difficult to see improvements from day to day, but when you compare how long you've held a plank between the first day of the month to the last day of the month, it can motivate you to continue your work toward greater core strength. You never "arrive" at a fitness level where you can stop and rest on your laurels, but you do experience benefits and results from the first week you start. Rodriguez says:¹²

"Planks are a great alternative to doing crunches. It improves the strength of your core musculature; of your abdominals, lower back, hips and shoulders. And it also improves posture and balance."

Basic Plank Maneuvers

In this eight-minute video, Rodriguez demonstrates plank positions you can use as a beginner, and includes variations to help you continue to improve your strength and balance. Remember the idea is to gently stress your muscles and connective tissue to improve your strength. This requires patience and time.

While you will see results within days, don't be tempted to increase your level quickly or you may suffer an injury. Each of these maneuvers can either be held for 30 to 60 seconds, or you may choose to do 20 repetitions. Here are several beginner plank maneuvers that work different muscle groups:

Don't Make These Common Mistakes

Rodriguez warns all planks must apply postural rules to reduce injury. These include:

• Shoulder, buttocks and legs in a straight line
• Head in neutral position, looking approximately 8 to 12 inches in front of you
• Abdominal and gluteal muscles tight and hips tucked in
• Shoulder blades pulled down
• Lower back in neutral position without excess or reduced lower back curvature

It may help to do your planks in front of a mirror, or ask a friend to watch and give you feedback about your position, or film yourself with your phone or camera to evaluate your plank position. When done incorrectly you may put more stress on your lower back and may not achieve the results you desire.

Three of the most common mistakes happen when your hips are either lower or higher than they should be, or when you look straight ahead instead of 8 to 12 inches in front of you. Each of these changes in position places strain on your back or your shoulders, making the exercise much less effective.

Remember, as you start, it may not look perfect. You just have to work to make it look better than it did the last time. With each new session you'll improve both your form and the benefits you experience. Practice patience and you'll be rewarded.
