Katie Price hasn't been to the gym "for years".
The mother-of-five has been enjoying some light horse riding in an attempt to get back to her normal weight after giving birth to daughter Bunny four months ago, but admitted she is going to hit the gym again in the near future.
Speaking on Australia's 'The Morning Show', she said: "I am starting to eat healthy now and I'm going to start the gym.
"I always say, 'On Monday I'm going to start,' but that Monday hasn't happened yet. There's probably a lot of things that people probably do to look good after having a baby.
"But, like I say, there is no pressure. I don't know what these Americans do or in fact some people in England, what they do.
"I think you either ping back or you don't, it depends on your genes and stuff.
"I haven't been to the gym for years so I normally ride my horses but I am definitely going to start the gym.
"I have to have a personal trainer when I do go to the gym, I can't train on my own because it needs someone to push me and I know that that hour is going absolutely kill me."
The 36-year-old star insists she isn't too worried about getting rid of her baby weight and believes other mothers shouldn't feel the need to pile off the pounds immediately after giving birth.
She added: "I would just say eat healthy and don't stress about losing that baby weight.
"Enjoy your moments with the baby because they do grow and eventually, when you're ready, because you've got to let your body settle, I say, it's not going to happen overnight so don't stress about it. What will be, will be.
"I was lucky this time with Bunny because I bounced back really quick and I haven't worked out.
But you know, everyone's body is different, don't stress about it and enjoy the baby."
Katie is also mother to kids Harvey, 12, from her past relationship with Dwight Yorke, Junior, nine, and Princess Tiaamii, seven, from her marriage to Peter Andre, and Jett, 15 months, who she has with 27-year-old husband Kieran Hayler.

Adele is working on a pop-orientated album.
The 26-year-old star has enlisted the help of hit pop producer Greg Kurstin to work on her highly anticipated third album, which suggests the record may be a lot more upbeat than her other recordings.
A source revealed: "Greg's a genius and one of the powers behind many pop hits.
"But it's a huge surprise he's working with Adele because it suggests she's considering taking a much more pop-focussed direction for her new record."
The producer has an excellent track record when it comes to making hits, with Take That's number one single 'These Days' and Kelly Clarkson's 'Stronger' among his many achievements.
The revelation comes days after the 'Rolling in the Deep' singer - who has two-year-old son Angelo with boyfriend Simon Konecki - was confirmed to be working with Blur frontman Damon Albarn on her new music, as she is nervous about living up to the high expectations set by her sophomore album '21' which has sold more than 30 million copies to date.
Talking to The Sun newspaper, the insider continued: "She's also had some serious concerns about the quality of her new album, so this is an indication that she wants a proven hit-maker on board.
"She knows the whole world is waiting for her new music and wants it to be perfect."
Greg - who is also known for producing Lily Allen's albums - is not the only musical genius who has been employed to work with the star, as Ryan Tedder, Diane Warren, Paul Epworth, and James Ford have all contributed to the album which is believed to be called '25'.

Miranda Lambert praised "her rock" Blake Shelton as she was honoured at the CMT Artists of the Year event last night (02.12.14).
The 31-year-old singer was given her award by Ashley Monroe after NASCAR star Danica Patrick introduced her performance of 'Holdin' On to You' and admitted she had been incredibly "nervous" but remembered to thank her 'Voice' coach spouse for his support.
Miranda - who was one of five recipients of the honour - said:
"I'm so nervous. I'm glad that's over. Thank you, Danica, thank you Ashley, for being here. Thank you, CMT, for this amazing night in honouring everything we work for so hard all year and all the amazing artists. My husband, I always forget to thank him, but he's my rock -- Blake Shelton.
"He's somewhere on TV right now, I think. But I appreciate it so much. And thank you so much to the fans for buying our music -- all of our music -- and giving us a great life and letting us live our dream."
Luke Bryan missed the event following the tragic death of his brother-in-law at the weekend but was in the thoughts of fellow honourees Jason Aldean and Keith Urban.
Jason said: "One of my buddies, Luke Bryan, is not here tonight, dealing with some family stuff in Georgia. Just want to say I'm thinkin' about you, you and your family. Our thoughts and prayers are with you all. Hurry back to the country music world."
And picking up his trophy, after singing James Brown's 'It's A Man's, Man's Man's World' alongside a 10-piece female band, Keith said: "I want to send my love and prayers out to Luke and all your family tonight too, brother. You're right here tonight, brother."
In Luke's absence, Lady Antebellum stepped in to sing 'Drink a Beer' with the track's co-writer Chris Stapleton and their friend was delighted by their fitting tribute.
Luke tweeted: "That was amazing. Truly. Thank you Charles, Dave, Hillary and Chris! Beautiful!!! Thank you fans for your love.(sic")

He said: "Anything I'd say would be short of the mark, so thank you very much and God bless you. Good music lives forever!"

Tracey Emin has turned the BRIT Award pink.
The British artist has unveiled her design for the distinctive trophy that will be given out at the 2015 ceremony and the design sees the iconic statuette turned a pale hue with a short verse written in blue script.
The words on the trophy, which are printed four times, read: "Congratulations on your talent on your life.
"On Everything you Give to Others
"Thank You (sic)"
The 51-year-old artist hopes the statue will be "special" to the recipients and says she worked hard to put her own stamp on it.
She said: "You want to do it really well. You don't just want to decorate it, you want to make something that is really Tracey-ish, that is special for the people receiving it."
In honour of the award's new look, the BRIT Awards with Mastercard's distinctive logo has also been turned pink and awards bosses are thrilled with her "bold and brilliant" idea.
BRITs Chairman Max Lousada said: "Tracey's design is characteristically bold, brilliant, colourful and inventive - everything the BRITs stands for. We're honoured to work with her and delighted to be able to celebrate the achievements of the BRIT Awards winners with such a unique and special trophy."
The BRIT Awards 2015 with MasterCard take place on Wednesday 25th February at The O2 in London and will be broadcast on ITV.

Dwayne 'The Rock' Johnson is in talks to star in new Disney movie 'Moana'.
The 42-year-old actor is being lined up to appear in the much-anticipated new Disney film, which will tell the story of an adventurous teenager who sets out on an impossible-looking mission to fulfill her ancestors' quest.
Dwayne - who's previously starred in 'Pain & Gain' and the 'Fast & Furious' franchise - is wanted to voice the part of a demi-god known as Maui, Empire reports.
In the film, Dwayne's proposed character joins Moana as she sets out on her mission to find a fabled island.
The pair must tackle an unenviable array of challenges, including a giant see creature, as they try to reach their end destination.
The new Disney animation is being led by Ron Clements and John Musker, the directors who were responsible for 'Aladdin', 'The Princess And The Frog' and 'The Little Mermaid'.
However, before possibly appearing in 'Moana', Dwayne will star in 'Furious 7', the latest film in the 'Fast & Furious' franchise.
The film, which is set for release in April, will also feature Vin Diesel and will mark the final on-screen appearance of Paul Walker, who died in a car accident on November 30, 2013.
Vin, 47, has previewed the film, saying: "We all went above and beyond to make Pablo [Walker's nickname] proud, but man, I wish he could see what we have created and just how far we have come."

Stephen Hawking wants to play a Bond villain.
The 72-year-old scientist and author - who has made a number of on-screen cameos in the past - has confessed his "ideal" role would be playing "a baddie in a James Bond film".
The wheelchair-bound physicist believes his computerised voice - through which he has communicated since becoming almost entirely paralysed by motor neuron disease - makes him perfect for the part.
He told Wired magazine: "My ideal role would be a baddie in a James Bond film.
"I think the wheelchair and the computer voice would fit the part."
Hawking - who is the subject of the upcoming biopic 'The Theory of Everything' starring Eddie Redmayne - appeared in 'Monty Python Live (Mostly): One Down, Five To Go' over the summer while the comedy troupe performed at the O2 Arena in London.
Monty Python star Eric Idle said it was a "lovely" experience starring alongside Hawking in the show.
He told Rolling Stone: "In some of the outtakes, I'm playing [Hawking] the 'Galaxy Song' and I keep making him smile; it's lovely.
"It's not easy to make him smile because he doesn't have much range of movement, but I see his mouth go up and it's just great."

'The X Factor' stars Andrea Faustini and Ben Haenow have been banned from eating biscuits.
The semi-finalists are said to have been banned from eating sweet treats such as biscuits and chocolate bars after piling on the pounds in recent weeks.
Revealing they've been put on a strict exercise regime in a bid to have them in better shape if they make it to the final, a source said: "Andrea and Ben have put on weight and it's becoming a problem.
"Andrea's always been a bit cuddly, but if he wants to be a serious pop star he needs to be in better shape.
"Ben is not exactly fat, but he's getting a bit of a belly and it's becoming harder and harder for the stylists to hide it."
Andrea is the last of Mel B's boys category while Ben is one of Simon Cowell's two over 25s and while they claim they're often very involved in choosing which songs to sing in the live shows, they've been given no choice when it comes to their new diets.
The source continued to The Sun newspaper: "We have spoken to them both and said they need to seriously think about whether they want a career in pop music.
"They need to cut out biscuits and get to the gym.
"That isn't a suggestion, that's an order from the very top."
The news comes after Italian contestant Andrea recently admitted he'd been resisting the show's attempts to get him into better shape.
He said previously: "'The X Factor' tried to put me on a diet. For three weeks I ate broccoli and grilled chicken. But I hated it. Yuk."

Scarlett Johansson has reportedly joked her baby gets starstruck around her.
The 30-year-old actress has two-month-old daughter Rose Dorothy with French journalist Romain Dauriac and she's said to have been overheard joking her newborn got starstruck by her appearance, like many of her fans.
A source - who heard Scarlett talking to a pal at the Gotham Awards on Monday (01.12.14) - told the New York Post newspaper's PageSix: "Scarlett was saying how her daughter's eyes lit up when she saw her in full makeup and with her hair done for the event."
The 'Avengers' star is also reported to have offered her sympathies to a fellow new mum who told the beauty about her struggle to keep her baby's food down.
The source added: "The other mum was just smiling and talking about how her baby keeps puking on everything. Scarlett was just smiling and nodding with empathy."
Meanwhile, it's been confirmed Scarlett and Romain - who have been dating for over two years - tied the knot shortly after the birth of their new daughter.

Kim Kardashian West made preparations to have her eggs frozen before conceiving her daughter North West.
The 34-year-old reality TV star, who is married to hip-hop icon Kanye West, has revealed she found out she was pregnant with 17-month-old North as she was about to undergo fertility treatment.
She explained: "A few years ago, I was told I could never get pregnant. Three different doctors told me the same thing, which is why I wanted to have my eggs frozen.
"I was just about to do that when I found out I was pregnant with North."
Kim, who has two sisters and a brother - Kourtney Kardashian, 35, Khloe Kardashian, 30 and Rob Kardashian, 27, as well as four other half-siblings - also revealed she would like to have two more children of her own.
The brunette beauty told ELLE UK magazine: "I want a boy and another girl; I want it to start happening straight away. I loved being part of a huge family - and I want that for North. We'd do IVF if nothing happens, but we both want to keep trying naturally."
Kim also revealed her pride at seeing half-sister Kendall Jenner, 19, become a major figure in the fashion world, having recently become the face of beauty brand Estee Lauder.
She said: "I think she will be a huge star. I definitely think she will be bigger than I have ever been."

Bill Murray wants most child actors to be "taken out and shot".
The 64-year-old actor really dislikes working with youngsters in his movies but has made an exception for 11-year-old Jaeden Lieberher, who he appear alongside in his latest comedy movie 'St. Vincent' and admits the star is "more professional" than the majority of older actors he's worked with.
He said: "Most kid actors should be taken out and shot, let's face it. And their parents too.
"Yet this kid [Jaeden Lieberher] was more professional than most of the actors I've worked with. He was completely prepared and he has a wonderful mother and father who keep him normal.
"He never became a movie-star brat."
Bill's rare praise of a child actor has certainly worked wonders for Jaeden as the veteran actor helped to get the youngster a part in his latest movie, an untitled Cameron Crowe romantic-comedy which is also set to star Bradley Cooper, Rachel McAdams and Emma Stone.
When asked if he would be prepared to work with Jaeden again, Bill replied: "I already have. I was making a movie with Cameron Crowe after I finished this one and Cameron asked me what I thought of him.
"I said, 'I don't like kid actors.' Three days later, I had to call him and say, 'OK, this kid's good.' The next day, Cameron hired him."
But Bill admits he is very selective when it comes to choosing his own roles and refuses to have an agent because they used to show him so many "crap" scripts.
He added to Metro newspaper: "Agents don't get paid if you don't work, so they're constantly jamming stuff in your face - mostly stuff from other clients in their own agency.
"I remember saying, 'Please don't ever give me another script written by these people. Ever.' Because there are some writers in Hollywood who just churn out crap."

Ed Sheeran received career advice from Prince William.
The 'Thinking Out Loud' hitmaker has revealed the British royal advised him to never duet with soccer star Wayne Rooney again after seeing a YouTube video of them singing Ed's hit single 'Lego House'.
Explaining that the conversation took place at the Royal Variety Performance earlier this month, Ed said William joked: "Er, no more duets with Wayne Rooney."
The 23-year-old star also spoke about how he came to record the performance with his unlikely singing partner - who plays soccer for Manchester United.
He told the Daily Mirror newspaper: "Rooney's been trying to come to a gig for three years.
"He actually booked me for his birthday party, but I had a gig the same night.
"Coleen [Rooney, his wife] came down to my Leeds show and said Wayne was going to come down to Manchester with a load of mates.
"She asked if I wanted to go out afterwards. I said I didn't want to go to a club, but Wayne hates clubs as well, so they rented out a lovely dingy pub that just did Jagerbombs and beer."
However, Ed wasn't the only famous face at the bash, as he also partied until 4am with Example and Wretch 32, before taking everyone back to his hotel room until 7am.
Meanwhile, the flame-haired singer confessed he's unsure whether William and his wife, Duchess Catherine like his music as much as they claim to.
He added: "I don't know if they're fans. Do royals have iPods and things like that?"
