Between each vertebra in your spine is a disc. This disc has a soft, shock absorbent centre and a stronger, stiffer outer binding. Under healthy conditions, disc cells receive a free flowing supply of nutrients and oxygen that are necessary to maintain their resiliency and metabolic functions. However, unlike most other cells of the body, they don’t receive these directly from blood vessels. Instead, disc cells receive their supply of nutrients by diffusion of water (Mooney, 2000).

The other day Peter shared an interesting fact with me that he’d learned from Clinical Exercise Physiologist, Aalia Desai – that just a 10% improvement in your cardiorespiratory fitness (CRF) may reduce your risk of a premature death by a significant 15%! That seemed to me a pretty good reason to find out how fit I actually was.
So I decided to let Aalia, who works at the ExerScience Clinic, put me through an exercise stress test – a first for me.

Back conditions are a significant burden of health loss across the population. The New Zealand Burden of Diseases, Injuries and Risk Factors Study, 2006-2016 ranked Low Back Pain (LBP) as the third biggest contributor to health loss in New Zealand, as measured in disability adjusted life years (DALYs). One DALY is equivalent to loss of one year of healthy life. It estimated that back disorders were associated with 27,112 DALYs in the New Zealand population in 2006 and that 10% of the New Zealand population, or around 437,000 people, had a back condition.
Costs associated with LBP that are covered by Vote:Health (the primary source of funding for New Zealand's health and disability system) are estimated to be about $215 million per year and more than $325 million per year when ACC costs are included.
Back pain is a big, expensive problem!

This weekend I re-grouted my shower. It took around 8 hours and was quite a workout. My forearms got so fatigued that I had to recruit my chest muscles to do a fly-type movement for a bit of horizontal flexion, squeezing out every last drop of grout from the tube. And it occurred to me, had I discovered the next big fitness craze? Grout Fit™. After all, it required a whole lot of effort and made my forearms ache like hell so it must be good for you, right?

For many years, it’s been a widely held belief that resistance training (or strength training) must be supplemented with some form of aerobic or endurance activity such as running to significantly improve cardiovascular fitness. But the truth is, there is no such thing as exercise for cardio vs resistance training as we’ve come to understand it.

If only there was a magic weight loss wand you could wave to help you shed fat, rev-up your metabolism and hold onto your muscle. Well, magic wands are in short supply, but that doesn’t mean it can’t be done.
That’s the good news from a new study released in February this year by researchers at McMaster University in Ontario, Canada. Their findings show that you can lose a significant amount of fat and augment your muscle in just 28 short days. But before we find out how they came to that conclusion, here’s a bit of background.
