I'm walking down the high street in south west London in Wandsworth Town and I am on my way to quite a fancy gym.

I get strict to press away you're loading the start off of five wrecks, 100% of your 10 rep max.

Once you've done that, your partner, we then do 100% of 10 rent max.

Then you go down to four reps, three reps, two reps, and increase the weight as you go along.

Strix press, as you can see the bar, it's going to come away down to his chest, full range, and four-rep-power.

This is Military Fitness London, a personal training gym owned and run by Grant King.

Grant is in his mid-30s. He's about six feet tall, athletic and has perfect hair.

But he's not supposed to be here. He's supposed to be in Qatar where a few years ago he'd managed to build himself his dream life.

Grant used to be a soldier.

That whole whole way through school, I kind of knew I was going to be the army.

Granddad was in the army, stayed in the army his whole life, loved the army.

I looked up to my granddad as well, kind of saw him as a bit of my idol.

He served on multiple tours in the British Army, including in Iraq and Afghanistan, over eight years. He'd seen and been through a lot. After leaving the army, he moved back home to Margate, the seaside town where he'd grown up. But there, he found it hard to slot back into life. I just kind of felt so out of a place, I didn't feel I belong there anymore. So I wanted to do something different. I thought I would take a year off. That's when Grant moved to Qatar to become a personal trainer, and he absolutely loved it. I was enjoying what I was doing, meeting new people, and getting kind of paid pretty well for it. So for me, for the first year out there, it was kind of like, and the guys I was living with as well, it was a bit like a lad's holiday as such. It was a very different experience. And it was, yeah, it's like more the longer I was there, the more I knew I was definitely not going to rejoin the army. And soon, he started doing pretty well there. And the reason why I think we worked is because I really went down that military route. I wore that military trousers. I let everyone know I was ex-military. So when running boot camps, if you want to kind of come to a real boot camp, come to mine because I'm military and the other people aren't. That's where he met Eleanor. They're married now. She's originally from Romania, but was working in Qatar as an air hostess for the royal family.

That was literally. met Eleanor. They're married now. She's originally from Romania, but was working in Qatar as an

air hostess for the royal family. That was literally a dream job for me. Why was it so good?

I had a wonderful accommodation, wonderful pay. Traveling was beautiful. I can't really complain.

It was just in lots of free time, lots, lots of free.

So I had a dream life.

Grant decided to start his own personal training business in Qatar.

After a year of being there, I decided to want to work for myself.

Kind of like the idea of not as such being controlled by somebody,

not being told what to do,
