A personal trainer who was told he wouldn’t live to be 30 is celebrating a transformative 13-stone weight loss.

Jordan Martinez (23) is maintaining his weight loss through regular exercise, including the fat-burning classes he teaches at Mansfield’s i-Jump trampoline park.

Jordan, who leads a range of fitness sessions for children and adults, said: “Being overweight at a young age was devastating for me. By the time I was 15, I weighed 16 stone. I found it incredibly difficult trying to control my eating and being cruelly mocked in school exacerbated the issue. Aged 20, my doctor told me I weighed 25 stone and that I wouldn’t live to see my 30th birthday — I knew I needed to change my life.”

After joining a weight loss club, Jordan learnt which foods were good to eat and through his own research understood how to exercise properly. As part of his exercise regime, Jordan enjoyed going to the gym and began teaching health classes at i-Jump.

“I’m ecstatic to have lost 13 stone since my weight loss journey began a year ago,” he said.

“My confidence has sky-rocketed and my relentless hard work has achieved life-changing results, which I want to use to help encourage other people to do the same.”

Stephi Grayson, operations manager at i-Jump, added: “We’ve seen a big rise in the popularity of our classes in the past year and Jordan is a real inspiration to everyone who meets him. We have extended our offering by running numerous classes to cover all ages and abilities.”

i-Jump trampoline park offers various classes including i-Tots for children under five, i-Keep fit for adults, and family jump together sessions.
