With new research from Fitness First showing that only half the population admit that they do enough to keep fit and healthy and only a third say they drink enough water, the Government's concerns about the nation's health are well-founded.

In my experience the thing that makes or breaks any fitness programme is that people don't see results immediately, and if you're like me it's hard to find the motivation to keep going.

I've discovered a pretty good system from the people at BUPA that measures not only the usual physical impacts of exercising, but also lets you actually see how well you're doing on the inside, monitoring 16 different physiological and physical signs over time.

It's only available in Fitness First clubs and in its pilot stage alone it's helped hundreds of people keep with their fitness programmes who would otherwise have given up, me included!

So let's turn back the tide on the growing obesity crisis once and for all. With summer on the way there's never a better time to get out there and get healthy.
