His wife Anna, 35, says his attitude gives her 'a kick up the bum'

Says when he gets chatted up by other women it keeps his wife on her toes

A 56-year-old man who splashes nearly £20,000 a year on his appearance says he does so to force his younger wife to keep up.

Donavon Nelson, from London, has forked out thousands on surgical treatments and has three personal trainers to hone his shape - admitting his intense grooming regime forces long-suffering wife Anna, 35, to stay in shape too.

The father-of-two claims that as well as enjoying his youthful looks his regime 'also creates pressure for her [Anna] to keep fit, fitness is very important to me.

'You don't want to marry one wife and find you get one three years down the line when they're twice the size. The whole idea is to try and keep them the same way that turned you on when you first met,' he admitted.

Donavon, who has had pectoral implants and several rounds of liposuction, spends three hours a day on his appearance including no less than 20 minutes brushing his teeth each morning.

A lot of help: The father-of-two has three personal trainers costing £300 a week, he spends $175 a month on his hair and using expensive cleansing products on his face

He also spends £50 a month on flights to return to London from Sweden, where his business is based, to visit his favourite hairdresser where his cuts set him back £175 each month.

He said: 'With my wife being 21 years younger than me, I want to maintain my body. At least I know if she ever leaves me I can still go on the market, I won't be left on the shelf.'

London-born Donovan claims he has to carry ID around with him because he's been turned away from nightclubs and refused alcohol for looking too young.

He said: 'I was on holiday in Thailand a few years ago and I was held up by border control for three hours.

'They had to wait for the UK office to open so they could check if my passport had been stolen because they couldn't believe my age.

'I also went to Tramps in London last year and they thought I was trying to get in on my father's membership and asked me if I had a second ID. It's embarrassing when I get turned away when I want to go out or buy alcohol. I'm used to it now.'

Motivation: Anna says that although she doesn't feel like the gym her husband inspires her to work out

Donavon's wife Anna said his strict regime gives her a 'kick up the bum' to stay on top of her own fitness.

While the 35-year-old journalist refuses to get her own personal trainer, she still works out three times a week.

She said: 'We both try to stay fit and healthy, and of course Donavon's extensive regime gives me a kick up the bum. I do pig out occasionally though.

'Sometimes I'll have no motivation to go to the gym and he'll be out training. I just think, "I'm getting fatter while he's getting fitter". It's like I'm the older one and he's the younger one."

But Anna says that while she struggles to motivate herself her husband does inspire her.

She added: "I think everybody should have someone who motivates them to go to the gym. At the time I might think, "Oh God he's on at me again", but once I've gone to the gym I feel fantastic. If I'd never met Donavon I don't think I'd be as motivated.

'Fitness is such an important part of his life and we've been together so long that it's become a part of me too.You want to do the same things, and his drive rubs off on me.'

Speaking about the 21-year age gap Anna said: 'He has so much charisma and everybody loves him. We meet in the middle - he tries to stay young and I have made older friends. I have a lovely husband, and he looks fantastic.'

Donavon says he loves being the 'trendiest dad on the playground' to daughter Aspen, 10, and son Damien, 13, and his efforts ensure he gets plenty of attention.

He said: 'All the other dads at the children's school are younger than me, but I'm the only one who can do somersaults on the playground.'

'I get chatted up a lot when I go out, which is very flattering. I never tell them my age, I just smile, but it keeps my wife on her toes when she sees these young girls flirting with me. It's all worth it because I can go to Ibiza and take my top off without being embarrassed.'

But while Donavon spends £300 a week on three different personal trainers he's also had several procedures to achieve his shape.

In 2012, Donavon had pectoral implants and then two bouts of liposuction in 2014 to boost his health kick. He spent £22,000 on the procedures, but has ruled out having anything else done.

He said: 'There were some areas where I was working out but the fat just wasn't coming off. There's only so much a surgeon can do and the rest is down to you.

'I thought, "I'll let the surgeon get rid of this bit of fat, then I'll work hard to keep it off". I was also lifting really heavy weights to try and build up my chest, but the doctor told me it was bad for me. That's why I had pec implants, for a quick fix.'

It's perhaps no surprise that Donavon has turned his obsession into a business and he now runs Scandinavian Boot Camp in Sweden.

The former marketing manager runs a £1,500-a-week 'fitness prison', where guests train up to three times a day for anything from one week to six months.
