To Crunch or Not to Crunch? That is the Question!
Crunches, are they hurting or helping?
As a trainer I hear a lot of people talking about wanting to get rid of their belly fat and replacing it with a six-pack.
Of course wouldn’t that be so nice if we could all get that six-pack?
But let me ask you this...
...what is the first thing that comes to your mind of what you should do to build
that six-pack?
If you answered crunches or sit-ups you are not alone.
That seems to be the go to exercise for trying to build strong abs.
Of course nutrition is a HUGE part of that goal as well but we are not going to address that part today.
Today, we are going to address which exercises will help you strengthen your entire core...
...WITHOUT HURTING YOU!
To start lets discuss what the core is really designed to do.
Without getting to technical, one of the core’s (which is your body less your arms, legs and head) main functions is to brace and provide STABILITY and CONTROL for the entire spine.
The core is also responsible for respiration (breathing), continence, postural control, joint/segment stabilization, and movement generation.
Another big function is to transfer energy from the feet up thru the hips and out to the arms and also in reverse (from the arms down to the feet).
Think of activities like:
- Walking
- Running
- Jumping
- Swinging a golf club or baseball bat
- Boxing
- Throwing a ball
- Yoga poses
So it is very important that we have a strong core so we can function properly and with ease in our daily activities and move thru sporting events injury free.
An example I like to use is to imagine yourself on a busy subway and there are no seats available, so you have to stand in the aisle and hold onto the hand rail.
You are holding on for dear life as the subway jerks along and you don’t want to fall over and land on someone’s lap. Well guess who is holding you up and keeping you from falling backwards or even sideways?
You guessed it, your core!
If your core is weak then it won’t be able to resist the outward forces being placed on it and you will end up sitting on some stranger’s lap. Embarrassing!
We need a strong core as well for sporting events, fitness, and even recreational sporting activities like playing basketball or softball with your friends or even with your kids in the backyard.
In sports, when you make contact with an opponent or even just contact with the ground while trying to quickly change directions to get away from your opponent, your core has to be able to activate and resist rotating so you can stay upright.
If you have a weak core then you’re are going to find yourself on the ground while your opponent goes right past you. Again, Embarrassing!
So what are the best exercises to perform in order to develop a strong core?
Anti-Rotation exercises are the answer. If you are doing 100’s of crunches everyday then you may actually be hurting your spine instead of creating a strong core.
You may feel like you have strong abdominals, but how does your back feel?
Studies have shown that sit-ups as well as crunches put a great deal of stress on the spine and over time this can cause back disorders for many people.
Spine expert Stuart McGill has shown that sit-ups will cause damage in most people. Just a single sit-up will produce low back compression levels very close to the National Institute for Occupational Safety and Health action limit.
McGill has gone on to say that repeating compression forces on the spine like this has been shown to increase the risk of back disorders.
In other words, when all you do is sit-up after sit-up you are wearing away at your spine making it weaker and susceptible to disorders like disc herniation.
Also, it the number of sit-ups or crunches it takes to cause these issues is not absolute. It is different for everyone as we are all made and move differently.
Another thing to consider if all you do are crunches is the fact that you are reinforcing poor posture.
If you are continually sitting all day whether it be:
- At a desk in front of a computer
- Driving
- Reading a book
- Drawing
- Sewing
- You
name it
...you are probably sitting with a rounded posture.
When we sit with a rounded posture we are flexing the spine and again when we flex the spine we are putting a great deal of stress on it which will lead to back issues at some point in your life.
The scary part of this is you don’t even have to be lifting a heavy weight for there to be damaging amounts of compression, just sitting this way alone is enough.
So now you go and do a ton of crunches and keep flexing that spine, guess what, you just hurt your back even more.
So what should you do??
You need to add anti-rotation exercises to your list of exercises to help strengthen and protect the core. These would include things like:
- Planks (there are many varieties and levels which makes this
great)
- Bird dogs
- Bridges
- Farmer walks or suitcase carries
- Pallof-presses
- Chops and lifts (again many varieties)
- Turkish Get Ups
- Medicine ball slams
- Stability ball or ab-wheel rollouts
The list is actually endless and the great thing about all of these exercises is that anyone can perform them no matter what level you are at in your fitness regime.
You can make them as hard or as easy as you want.
Also, there is no boring same old routine, you have so many different movements you can do to add variety to your workouts.
And BEST OF ALL?
...you are building that six pack without causing any undue stress to your spine.
