Whilst most people were frantically buying paddling pools and scavenging for the last ice-cream in the freezer, I spent the hottest day of the year sprinting, squatting and repeatedly being shouted at to "go faster".
If you think that sounds like a living nightmare, you'd be marginally correct - but I promise I didn't have a death wish.
I had signed up to join former UK Special Forces soldiers, Jason 'Foxy' Fox and Matthew 'Ollie' Ollerton, for a workout - and they aren't the type of guys you can let down, even in 40C heat.
