Adele's former personal trainer has claimed that the star's competitive side is the secret to her seven stone weight loss.
Pete Geracimo worked with Adele for her 2016 and 2017 world tour and revealed that although the singer wasn't a big fan of working out, she always wanted to outdo herself in every session.
The pair worked together for one hour sessions, two or three times a week as she kicked off her fitness journey.

Pete told Us Weekly that the training also helped with Adele's mindest, noting: 'When we had low days, I would alter the workout so that it would ease her into training, get her mind off of what was bugging her and then, before you knew it, we were having a good session and working hard.
'I don't get starstruck and just trained her as if she was not famous. I loved her sense of humor and we'd laugh a lot of the time.'
Pete added that Adele always wanted to outdo herself, noting it was her competitive side that spurred her on, even though she 'wasn't a fan of training in the beginning.'

Now that Adele lives in the States, she is said to have enlisted the help of a fitness guru who trained Lady Gaga and hired a personal chef.
The singer reportedly took advice from LA-based trainer Harley Pasternak, who has also worked with the likes of Rihanna and Katy Perry.
It's also claimed that Adele hired a personal chef on the advice of her Hollywood pal Cameron Diaz because she's 'not a fan of cooking.'

A source told The Sunday Mirror that Harley suggested Adele follow a fitness regime which included 35-minute training sessions five times a week.
They said: 'Adele is feeling incredible at the moment and her weight loss is due to a lot of things but she is also been getting tips from Harley.
'Lady Gaga told her how brilliant Harley was. And that convinced Adele to get in touch.'

It was then reported that Adele hired chef Jason Harley to create her healthy dishes, following claims she had been following the 1,000 calorie-a-day Sirtfood diet.
The source added: ''She would have a green juice in the morning then work out. The she wouldn't usually eat until 3pm or 4pm so she was also doing a lot of intermittent fasting.'
Back in October, Adele had already visibly lost a great deal of weight as seen in pictures of her attending her friend Drake's birthday party.
She posted an Instagram snap of herself at the fete and quipped in the caption: 'I used to cry but now I sweat'.
