3 worst core exercises for people with low back pain

The power of the internet can’t be doubted.

It has the ability to spread knowledge across the globe in real time. You have a problem, google it, and more than likely you’ll find a solution.

So what’s wrong with that?

As a physiotherapist in Toronto, these are the questions I ask myself: How good is the information you’re getting? Is it valid? Reliable? Can it be trusted? Will it help you? Or will it hurt you?

This holds even more weight when dealing with physical issues such as injuries or illness. Plug in your signs and symptoms and within seconds, hundreds, if not thousands of webpages will be returned for your perusal.

It’s no different with relieving low back pain. Plug in those search terms and instantly you’ll have at your disposal more information than you could possibly even use.

When looking at low back pain, a good portion of the information that’s returned discusses strengthening your abs to fix your back problems. At times, this is similar to the information many people are given by their medical and fitness professionals: “Build a strong core to protect your back”.

Unfortunately, abdominal training is typically considered the foundation of core training. In reality, abdominal training is only a small part of the bigger picture. And in some cases, poorly designed or applied abdominal training can actually be what’s keeping you in pain.

As I’ve already talked about six pack abs and low back pain, I’ll just stick to giving you some ideas on how to keep your back strong, safe and healthy. Without further ado, here’s my list of the 3 worst core exercises for people with low back pain:

The abdominal crunch or sit-up: These staples of most back rehab programs should be eliminated because of the tremendous compressive loading forces that they create through the discs of the spine. There are better ways to train the core!

Dr. Stuart McGill, one of the foremost spine researchers in the world, has measured compressive forces of approximately 3300N (730 lbs) in the spine with these types of exercises.

This is equal to the amount of force noted by some government health agencies as the amount of force needed to cause injury!

Abdominal machines (crunch and twist machines): So if crunches or sit-ups can cause as much damage to your spine, imagine what happens when you take the same exercise, restrict movement at certain joints, isolate movement at others (in this case the lumbar spine) and then add a load.

Doesn’t sound very good, does it?

Now take that same flexion movement add a loaded rotation component on the twisting abdominal machines and you’re well on your way to getting yourself sent off to the disabled list.

In fact, we’ve  dubbed these types of exercises “disc herniators” and inform our clients on continuing to do these only if they wish to help us finance our latest exotic car purchase.

Take home message: save your spine and stop flexing and/or twisting through your low back!

Back Extension Machines: As described by Dr. McGill, the repeated spine flexion/extension movements used by these devices create the same conditions that were necessary in his lab to produce disc herniations.

Enough said.

Why would you want to do the same to your back at home?

So there you have it…The 3 worst core exercises for people with low back pain. If you love your back, stop doing them.

Let me know your thoughts. Do you agree? Disagree? Or just not care?

Yours in movement.

Six pack abs and low back pain.

In the realm of injury rehab which includes low back pain prevention and treatment, there are many exercises that are extolled as imperative for proper function. Most of these are granted the high honour of being called “CORE” exercises.

Stabilize your core. Strengthen your core. Turn on your core. Activate your core. 

I’m sure all of these are very familiar statements that you’ve heard when dealing with your low back pain. 

The problem with many of these is that they don’t actually take into consideration the functional anatomy of the involved or recruited structures. 

Let’s take a closer look at some of the muscles that make up the abs…

The rectus abdominis or “six pack” muscle is essentially formed by two bands of muscles which are further sectioned into 8 “rectangles” by intersecting tendons.

So why is the structure so important?

For starters, the structure of anatomical body-bits is defined by the purpose of those body-bits. 

Form follows function.

According to Dr. Stuart McGill in Ultimate Back Fitness & Performance the “rectus, by virtue of its beaded architecture, is not made to create force over a range in length-yet it is currently popular to perform curl-ups over a gym ball for example.”

In even more basic words, by its design, the six pack muscle was not designed to perform sit-up type motions, if it were, it wouldn’t be sectioned the way it is.

Instead, it would be two long uninterrupted bands of tissue (much like the hamstrings muscle on the back of the thigh). 

So if it isn’t made to crunch, what’s it made to do?

Based on it’s elegant design, the abs were made to RESIST motion and transfer power from the hips.

One of the best exercises to train this quality is the front plank as demonstrated in the following short clip.

Yours in planking.
