1) Without them, our spine would have problems!

The multifidus muscles help to take pressure off the vertebral discs so that our body weight can be well distributed along the spine. Additionally, the superficial muscle group keeps our spine straight while the deep muscle group contributes significantly to the stability of our spine. These two groups of multifidus muscles are recruited during many actions in our daily living, which includes bending backward, sideways and even turning our body to the sides. Studies have shown that the multifidus muscles get activated before any action is carried out so to protect our spine from injury.

2) The key is training your body to breathe while engaging your multifidus!

One of the reasons so many people have lumbar back pain is a result of not taking full breaths using their diaphram muscle in their lower abdomen. So often we take short quick breaths using our upper back and neck muscles because this is the most efficient way to get oxygen to our heart quickly. But when not in quick need, it’s important to contract that diaphram so that the multifidus learns it should be engaged all the time. Taking long sustained breaths in and out retrains your body to use your diaphram rather than your upper neck and shoulder muscles to breathe. You can imagine the tightness and pathology you may sustain by breathing from your neck, shoulders and back rather than from your deep abdomen–The upper extremity muscles get tighter and more bulky (theoretically causing lactic acid buildup and reduced oxygenation). This can result in a compression of the cervical spine and a weakness in the lumber multifidus.

3) Key exercises for keeping this muscle strong:

Pelvic Bridge: Press back flat into floor, raise hips towards ceiling. Hold for 2-3 seconds. Repeat 10x.

So I’m developing a CoreFit Deck that you can take with you. Get the first of these workouts here and print out so you can just grab them and go to the gym. In fact, why not just take a few in your gym back so all you have to do is follow the pictures and do the routine. Simple. And it won’t even show up on your data usage.

1) Ejaculation. Research published in the Journal of the American Medical Association suggests ejaculation, through sexual intercourse or masturbation, can reduce your risk of prostate cancer and can keep your prostate in check. But not just any kind of sex or masturbation;

Alright, let’s face it, I know you guys are all a sucker for a pretty face. And while this intro picture might be a clever ruse to draw you in to checking out this POWER UP workout challenge, I’m willing to bet you either want to look like this guy, or be with this guy. To do either, you have to have a body to match. Try CoreFit Challenge #14 to power up through plyometrics, and full body core work. If you want to really push yourself, add a 50m sprint in between each exercise without resting.

CoreFitChicago’s 30 Day Challenge #14 is Donkey Kicking: Do as many as you can for 1 minute. How high and fast can you kick your legs up?!?

Just to prove to you that working out does make daily changes to your body, I will post Monday’s before and Friday’s after shot as the grand finale.

Game on!
