Spencer Matthews showed off an amazing body transformation image and explained the motivation behind his emotional fitness journey.
The Made in Chelsea star, who has three children, waved goodbye to his 'dad bod' and revealed his rock hard abs in a shirtless snap on Instagram.
The previous image was taken 10 years ago during Made in Chelsea filming when he said "my life was spiralling out of control" with a drink problem.
He said: "I would drink to excess almost daily and had a deluded sense of grandeur."
Spencer was barely recognisable in the new image which was taken following months of training and discipline for his Everest trek.
In the post, he wrote: "In the picture on the left, my life was spiralling out of control. It was during Made In Chelsea and I had a drinking problem. I would drink to excess almost daily and had a deluded sense of grandure. I was uncomfortable in my own skin and change felt like too much of an effort.
"I thought that because I was a prominent character on a popular TV show that things would just happen for me, not realising that any kind of real success only comes through hard graft and determination.
"I had no routine, no motivation, no drive and no plan.
"My unsustainable appetite for socialising became detrimental to my health and wellness.
"On the right, 10 years later, I’ve embraced a different lifestyle and have self-discipline and a purpose. I’ve been training religiously, weightlifting three times a week, running, not drinking and being mindful of my health."
He said: "A routine, clear plan and consistency is important. Your goals won’t achieve themselves. I used to be out of breath walking up a single flight of stairs."
"I’m currently bang in the middle of training for the Jungle Ultra for The Michael Matthews Foundation - a 230km self sufficient foot race through the Amazon Rainforest.
"MMF was founded over 20 years ago in memory of my late brother Michael who passed away during his descent from the summit of Everest. The foundation works to provide education and safety to children in remote and underprivileged areas in rural Tanzania. We’ve helped over 7000 children so far.
"This race is challenging, but it's nothing compared to the struggles that these children would face every day without our support…
"I'm delighted to be running for a cause that means so much to me, and I hope to make Michael proud.
