Everyone has been there at some point. How do I get started? Or how do I get back into it having been away for so long?
Well, the following women have all found themselves in that same situation and are on hand to offer their support, help and encouragement.
Booticamp Babes creator and Belper/Codnor instructor Sarah (AKA Booti Momma) has been helping to get women active since beginning her own journey to get fit.
"I have been on my own personal weight loss journey nearly all of my adult life and I can completely identify with ALL women who are overweight and lacking confidence. You see, since I can remember, I was always an overweight child.
"I totally understand how feeling fat can affect you: the inability to join in team games, the bullying, not fitting in with the popular crowd, the hatred of waistbands, crop tops, skinny jeans, the lethargy; the panting caused by the smallest bit of exercise, the panic induced by the thought of a beach holiday; the pain of looking in the mirror; the lack of confidence and feeling thoroughly miserable...
"After the birth of my gorgeous daughter Ellie 14 years ago, I was on a mission to lose the five stone that I had gained. In 13 years I tried EVERY diet going, you name it I did it, like most women I lost the weight then piled it back on!
"It wasn't until 2010, that I tried the concept of clean eating coupled with exercise three to four times a week. I was sceptical at first and I was horrified at what I had to cut out of my 'normal' diet!
"However, I saw my weight literally fall off - in four short weeks I dropped a dress size and lost 9lbs and since following this lifestyle choice, I have lost a further 10lbs and have NEVER put that weight back on again, although I am human and like EVERY women, I can fluctuate a few pounds here and there.
"I launched Booticamp Babes in July 2012 and along with my fantastic team, we help women understand their bodies and show them how to take control of their lifestyle, say goodbye to faddy diets, yo-yo-ing weight loss/gain.
"We help them to cope with life's demands and support them if they are suffering with low self esteem, desperation, depression, comfort eating and despair. We help them learn or love their bodies by becoming fitter and healthier.
"We provide weekly nutritional plans, including recipes and tips and we have a secret Facebook group dedicated to our members to give them as much motivation and support as we can so we can help them achieve their goals.
"Alongside all of my fitness qualifications gained, including Level 2 fitness, Boxercise, Nutrition, Older Adults, GP Referral and Kettlecise, I am also a nurse with over 19 years experience, 13 of those years specialising in Aesthetics - which is another passion of mine - helping women to look and feel good from the inside out is my absolute passion.
"Along with my amazingly loyal, dedicated, fantastic team, I currently run 25 Booticamp sessions a week in various locations throughout Derbyshire and Nottinghmashire and have recently opened a camp in Birmingham too."

Mum and Derby Telegraph Digital Football Writer Kerry, 36, from Heage, worked her way back to fitness after taking time out.
"I've always enjoyed sport and keeping fit; I danced as a youngster and played netball. And I held the school long jump record for five years!
"But when I found out I was pregnant with my little boy Samuel, now aged nine, I took some time off.
"Getting back into exercise after having a baby can be tough, nerve-wracking even. I had stretch marks which made me self-conscious, wobbly bits which I hadn't had before and the thought of walking into a room full of people who, in my mind, were thin, toned and athletic, scared me.
"My weight rocketed and, as an early Christmas present, my husband, Nick, bought me a year's gym membership at Ripley Leisure Centre.
"It was the best present ever. Staff were brilliant; they encouraged me, praised me and made me feel fantastic!
"My confidence grew and I started regularly attending classes like Body Combat, Sh'Bam and Body Pump. The teachers – Steph Burton, Kathy Smith, Steve Summers, Simon Donlan and Kerry York – have all been amazing and they too, have such inspirational fitness stories. Steve is a retired fire-fighter who almost lost his life in an accident; he piled on the pounds and, at his heaviest, was 21 stone.
"The Leisure Centre have daytime and evening classes, so there is often one that fits in around looking after the children.
"I've not only lost weight but I've toned up, made some fab friends and I feel so much better. I'm more confident, healthy and alert.
"I've also enjoyed getting back into running with the Jog Derbyshire group in Ripley and, since joining them, have competed in my first 10k run.
"The Ripley Girls Can campaign is great at highlighting the variety of sport and activity on offer in our town.
"Remember, everyone has to start somewhere. You won't regret it!"
Get in touch with me at @KerryGanly or https://www.instagram.com/kezzaganly/, and I'll try and answer any questions you may have. I look forward to hearing from you.
Ripley woman Sally Green has put her body image issues behind her and carved out a new career as a fitness instructor.
"Firstly, I think that the Ripley Girls Can campaign is fantastic! I played sport when I was younger, and carried on with fitness when I joined the Navy.
"Having had my own body image issues and being really overweight to the point it impacted on my health, I can really relate to those who are worried about taking those fearful first steps!
"I used to think when the doctor told me to lose some weight he was just using it as an excuse and rebelled a bit... but guess what, he wasn't wrong!
"I have battled with my weight the last few years and passed my fitness qualifications and finally I am ready to use my experiences to help others, and to prove that fitness and the instructors are not a one size fits all!
"It's not all hard work and no play...because that's not the world we live in, it's about fitting in what activity we can into already busy lives!
"I have recently given up my 'big girl' job and currently work at Group Fitness in Loscoe. We have a fantastic bunch of instructors here and no-one is made to feel self conscious or uncomfortable... I absolutely love my job.
"We offer varying levels of classes and personal training sessions to suit everyone from beginners to marathon runners."

A passion for dance has seen Ripley Booticamp Babes instructor Julie (AKA Maniac) rediscover her love for staying active.
"I've had a love of dance since I was three years old and this led into a passion for health and fitness after leaving school. Following the arrival of my two gorgeous daughters, I struggled to lose the weight and get back in shape despite trying various fad diets!
