We’ve all been there, at least metaphorically.

You’re driving home from the end of a big day, going maybe just a little too fast to see the bed of nails.

‘POP!”

One of your tyres goes out.

As you pull over to the side of the road to survey the damage, your sanity escapes you, expelling like the air from that punctured tyre. So you do what any once-rational person would do in that situation and slash the other three.

Hours later, once you have returned from the descent into madness, you finally decide to call the tow truck guy to replace not one but four flat tyres!

In coaching, this is called flat-tyre syndrome, commonly known as the ‘What-the-hell’ effect in psychology, and it’s a real killer of fitness and weight loss progress.

It’s not that hard to picture yourself being affected by this.

You’ve been sticking to your diet, weighing and timing everything perfectly. Then you decide to have ‘just one bite’ of a restricted food, which turns into two, which quickly becomes four and then the whole packet. As the potato chip company Pringle’s aptly coined catchphrase tells us, “Once you pop, you can’t stop.”

The problem is twofold: it's both a problem of physiology and psychology.

So in this week's episode of The Enterprise Fitness Podcast, I tackle where to begin making changes that you can stick to.

This episode was filmed and recorded at a recent Internship I ran for trainers, were I spilled the beans on what it takes to get head-turning results.
