Two things became immediately clear: the gym is where you go to be seen and 99 per cent of the people there, almost by definition, have no need to be there.
It is no place for your comfortable old clothes, to puff and pant in private as your body sweats and wobbles in shame.
A whole new wardrobe must be acquired, one that holds curves tightly beneath bright logos and is as short and uplifting as the mantras churned out by the army of personal trainers.
So why not go for a run in the park instead? Well, knowing that a large amount of money is being spent on my membership keeps me motivated and, now that I'm pregnant and following a special pregnancy programme, I'm sure that both my baby and I are better for it.
But the real benefits are those I hadn't foreseen: the guilt-free television on the step machine, the hydropool and the numerous classes. Soon I'll be putting the crèche to use as well. But, most importantly, my gym membership gives me a few hours each week to escape work and home. Now, when I miss a phone call, I can reply with smugness, ‘Sorry, I was in the gym.'
