## Getting The Most Out Of Your Exercise

### Author: Dr. Pierre DuBois

Finding the body’s target heart rate (THR) is essential for those interested in maximizing the effectiveness of their workouts and training programs and reducing the risk of overexertion.

The Simple Method For Calculating Your Target Heart Rate

There is an easy method for determining your THR: Start by subtracting your age from 220 (226 for women); this will provide your estimated maximum heart rate (MHR). Multiply your MHR by the percentages listed for the appropriate exercise zone from the list below.

• Healthy Heart – For low-intensity exercises and warm ups. The THR for this zone is 50%-60% of the MHR.
• Fitness – For more intense but generally low to moderate effort exercises. The THR for this zone is 60%-70% of the MHR.
• Aerobic – This zone helps build endurance and increases the strength and size of your heart. It also improves your cardiovascular and respiratory system. The THR for this zone is 70%-80% of the MHR.
• Anaerobic – For performance training. This zone increases the amount of oxygen you can consume during physical exertion. The THR for this zone is 80%-90% of the MHR.
• Red Line – For maximum intensity exercises that burn the most calories. The THR for this zone is 90%-100% of the MHR. This level should only be attempted by those in excellent shape who have been cleared by a physician or qualified medical examiner.

So, for example, a 40-year-old woman who wishes to find her THR for a fitness zone program would use the following equation: (226 – 40) X 60% = 111 (low end) and (226 – 40) X 70% = 130 (high end). Therefore, as long as she maintains her heart rate between 111 beats per minute (bpm) and 130 bpm, the woman is at the proper target heart rate for maximum exercise efficiency and safety.

A More Accurate Method

MHR = 220 (or 226 for women) – age (in years)
RHR = average resting heart rate (average of 3 readings)
HRR = MHR – RHR
THR = (HRR * target zone percentage) + RHR

So for our hypothetical 40-year-old woman targeting a fitness zone…

MHR = 226 – 40 = 186.
RHR = (64 + 62 + 63)/3 = 63
HRR = 186 – 63 = 123
THR = (123 * 60%) + 63 = 137 (for the low end) and (123 * 70%) + 63 = 149 (for the high end)

If you have any doubts or questions about the proper method for determining your THR, ask your chiropractor, physical therapist or doctor for help.

Thank you for posting this. Very valuable information as I am approaching training for a challenging fitness goal. Thank you!

Dr. Dubois, is one of these zones best for burning fat? Seems like a few years ago we were being encouraged to exercise in one of the less intense zones in order to burn more fat. Should we do that or simply try to burn the most calories we can during our workout? Thanks.

Dear Teresa,
To keep things simple, it is important to understand that during exercise your body gets energy from primarily two places: fat stores, or glycogen stores. Glycogen is stored carbohydrates in your muscles and liver, and fat in the fatty cells. At lower exercise intensity (50% max HR), more fat is burned relative to glycogen(50%Max HR=605fat/40% Glycogen, 75%max HR, 35%fat/65%glycogen and so on).

Studies showed that for a 30 minutes low vs high intensity work out, the total calories burnt are 200 for a low intensity group, vs 400 for a high intensity group. But out of the 200 cal of the low intensity, 120 were from fat and 80 from glycogen, and out of 400 cal of the high intensity group, 140 were from fat, and 260 from glycogen.

You can immediately see that increasing from 50 to 75% of the max HR only increase the fat mobilization by 20 cal, which is not very efficient. Furthermore, when somebody starts exercising and is not used to it, pushing them rapidly into the 75-80% MHR will have them crash early. They will stop the exercise before the 30 mins. and therefore end up burning even less fat.

But as their fitness level increases, it is in my opinion a good idea to go into higher % of the MHR because of the following reason: If you exercise at a 50% MHR, when you stop it is the end of it. If you exercise at a higher level, there is a metabolic disturbance that burns calories after the workout is completed: it is the after burn effect (exercise speeds up the metabolism and keeps that accelerated rate going even after you’ve completed your routine. This “after-burn” effect can last from 15 minutes to 48 hours, depending on how hard you exercise).

To conclude, there is no “one size fits all” way to look at it. But based on the science we have on hand, we want to try to exercise as hard as we can for as long as possible without hurting ourselves. But the work out must be increased gradually in time and intensity, and associated with a well organized recovery time to insure the capacity to burn fat for a long time.

Probably a lot more than what you hoped for…but as you know very little is black or white.

Have a great day,

Pierre

## How to Choose the Right Pillow

Wake Up Each Morning Pain Free

The way you sleep is often a key to discovering the cause of headaches and more. If you wake up with neck pain, a headache, or you suffer from ringing in your ears, dizziness, or ear pain, there is a good possibility that it may be caused by the way you are sleeping. Your pillow may be the culprit.  But if you need to know how to choose the right pillow for you, it’s easy.   It just takes a little “investigation.”

## How to Choose the Right Pillow if You Sleep On Your Side

Your head, neck, and spine need to always stay in a nice straight line, just as it is when you are standing up, but that takes a little thought and understanding of the way you sleep.  So, get comfy in your bed and then notice how your head is resting.

If you sleep on your side, your pillow needs to be just the right size, so your head doesn’t point down toward the mattress (your pillow is too soft) or up to the ceiling (your pillow is too thick). Either of these positions will make the muscles on the side of your neck stay in the contracted position for hours and pull your vertebrae in that direction, especially when you try to turn over to your other side.

### Your SCM Muscle May Cause Serious Problems

You also need to notice if you turn your head a bit, especially if you are turning into your pillow or turning your head up toward away from your pillow. In either of these two cases you will be causing your sternocleidomastoid (SCM for short) to be held shortened for hours.

Your SCM originates on your collarbone and inserts into the bone behind your ear.  When it contracts you turn your head to the opposite side. However, if the muscle is tight (for example, when you’ve held your head turned toward one side for an extended period of time) and then you bring your head back so you are facing forward, the tight muscle will pull on the bone behind your ear and cause havoc.

The symptoms for a tight SCM are tinnitus (ringing in the ear), dizziness, loss of equilibrium, ear pain, headaches, pain in the eye and around the skull, pain at the top of the head, and even pain in the throat. Amazing! What’s even more amazing is that it’s rare that this muscle is considered when a medical professional is searching for the cause of your symptoms.

These are the things to know when considering how to choose the right pillow if you sleep on your side.

## How To Choose The Right Pillow If You Sleep On Your Back

If you sleep on your back, your head should be on the mattress (not propped up with a pillow) and you should have a tiny support (like a folded washcloth) under your neck.  Or, you can have a wedge pillow that starts at your mid-back and gently raises your entire trunk and head up while still allowing your head and back to be in a straight line.

It’s tricky, but I can personally attest to the fact that it will work.  I can always tell when I’ve had my head tilted (I toss and turn during the night) because I will wake with a headache. When that happens I’m grateful that I know how to self-treat the muscles of my neck and shoulders so the headache is eliminated quickly.  If you already have Treat Yourself to Pain Free Living,  you can self-treat all your neck and shoulder muscles to release the tension.

## How To Choose The Right Pillow If You Sleep On Your Stomach

If you sleep on your stomach, this is the one position that is so bad that it behooves you to force yourself to change your position. Your head is turned to the side and held still for hours, putting a severe strain on all your cervical and upper thoracic vertebrae. Not only will this cause headaches, tinnitus, and a list of other pains, but it can cause problems down your entire spine. It can also impinge on the nerves that pass through the vertebrae on their way to your organs.

If you do sleep that way, let me know and I’ll give you some suggestions that work to change your habit of sleeping. It takes time and energy, but the results are worth the effort.

In every case, the way you sleep may cause neck pain that won’t go away until the pillow situation is resolved.

Now you should know how to choose the right pillow for the way you sleep.

Wishing you well,
