Are You Still Doing Cardio?

Author: Kai Fusser, MS

Sprint Interval TrainingLast month I told you about functional fitness training and why I think it is superior to workouts on the machines that fill most gyms and sports clubs. This month my topic is sprint interval training, and why it beats the traditional cardiovascular or aerobic exercises.

Walk into any gym and the first thing you see is people straddling treadmills, ellipticals or bikes for 45 minutes or more trying to burn calories and improving their aerobic fitness.

It is not an easy task for me to explain in a short fitness tip why we should stay away from the typical low to moderate-intensity continuous training (“CARDIO”) and instead do sprint interval training (SIT, or burst training), but here are the key points.

The Problem With Cardio Exercise

 

Slow cardio:

  • is very time intensive (the number one reason people skip their workouts)
  • only works on your aerobic fitness (and that fairly inefficient)
  • burns some calories during the activity but has no impact on your overall metabolism
  • stresses your joints due to repetitive impact (especially if you are running for your cardio)
  • increases inflammation

 

The Benefits of Sprint Interval Training

 

Now here is a solution for you. SIT (sprint interval training) training:

  • will only take about 4-8 minutes 3 days a week
  • works your aerobic and anaerobic system at the same time
  • will raise your metabolism for several hours after you have completed the exercise
  • is very effective for fat loss
  • will build “fast muscles”
  • reduces impact on your joints and helps reduce inflammation

Sprint training can burn the same calories as slow cardio in 1/15th of the time! In addition, slow cardio exercise produces a lot of stress hormones (cortisol) while sprint training stimulates growth hormone (have you ever compared the physique of a sprinter to a marathon runner? It’s your choice).

It is the intensity, not duration that effects the adaptation to exercise.

 

Making Sprint Interval Training Work For You

 

There are different ways to implement SIT training:

It can be done on equipment like a:

  • treadmill (using a steep incline rather than high speed)
  • stationary bike
  • upper body ergo meter
  • or a X-iser

Or it can be done with no equipment at all, like

  •  sprinting (athletes only)
  • running up a flight of stairs
  • running up a hill
  • or with full body calisthenics like a Turkish Getup.

I recommend that you start with 4 min workouts (add 2-3 min of warm up before) with a sprint to rest ratio of 1-3, say 10 sec sprint with 30 sec rest (slow pace). As you feel more comfortable you should work your way down to a ratio of 1-1 like 20 sec sprint with 20 sec rest. The maximum total time you would want to do is 8 min. (more is not better in this case).

Please remember that the sprints should be “high intensity” which is of course relative to your fitness level. The intensity will be different for a fully trained athlete than for a de-conditioned couch hugger.

 

The Bottom Line:

 

Sprint interval training (SIT) is a quick and efficient way to burn calories and get the cardiovascular exercise your body needs.

You will be surprised how quickly your:

  • body will adapt to the new and positive exercise stress
  •  energy level will increase
  • performance will improve,
  • metabolism will pick up

You will save time and wear on your joints. Most of all, it can be fun !

    You have done a fantastic job of clearly explaining the difference between traditional cardio and sprint interval training. So many people think you need to be on a treadmill for 45 minutes. You provided some great information and options here for many people that don’t have time for extensive exercise every day. Thanks!!

    Wow. I’m one of those who has put off any type of exercise program because of how much time it takes (or so I thought) to accomplish anything. (I was a subscriber to the low cardio training you describe at the beginning of the article.) Now I feel like there’s some hope for getting into shape without the huge time committment. Thank you!

How to Choose the Right Pillow

Posted April 17, 2018 by Dr. Steve Chaney

Wake Up Each Morning Pain Free

how to choose the right pillow without headachesThe 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.

how to choose the right pillow to sleep painfreeIf 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

how to choose the right pillow for sleeping on your backIf 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 always a challenge for people who toss and turn during the night, sometimes on their side and sometimes on their back.  The best thing I’ve found for this situation is to have the pillow below shoulder level so when you turn on your side your shoulder will automatically slide to the edge of the pillow while still supporting your head properly, and when you turn onto your back, the pillow will start at shoulder level so your head and neck are supported, but your head is being pushed in a way that causes your chin to move down to your chest.

hip pain causes and treatment pain freeIt’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,

Julie Donnelly
