Skinny teen claims she got a Kim Kardashian ‘bubble bum’ by copying her Instagram idols’ workouts

She said: “At first, because I was younger, I didn’t know much about weight lifting, so I stuck to cardio. Then after six months, when I turned 16, I started using the weight section of the gym.

“For the past two years, I have been lifting heavy weights, training my legs around four times a week, upper body three times a week and working on my abs all the time but only for 15 minutes each time.

“When I first started going to the gym, I was 15 years old, I didn’t have much of a bum and I was so un-toned. I wanted to grow my bum and lean down.

“I was very unhappy with my body to start off with, but I always think that is the best kind of motivation, to do it for yourself.

“I wanted to change my figure because I started following more fitness girls on Instagram.”

Charlotte said when she started his mission she wanted to put muscle on, so to do this, she did little or no cardio.

The fitness star said: “When I bulked, I decided to then target my fat to reduce it and to start ‘cutting’, all I needed to do was increase cardio to five times a week and do the exercise for around 15 to 45 minutes.”

While previously, Charlotte would constantly compare her body to other people, she says she now feels confident in her own skin.

She said: “I think it’s fair to say it has changed my outlook on life and personality completely. I now feel extremely confident, of course I still have moments where I am not, but that’s normal for everyone I think.

“Overall I’m confident within myself and I don’t let things get to me easily. It’s also a great stress relief.

“I increase my protein intake in my diet. When I’m cutting down, I’ll add more cardio into my gym routine and luckily I don’t need to cut down how much I eat because I love food.”

To achieve the results she wanted, Charlotte has had to try many different techniques that didn’t always go to plan. She says this was the hardest part of the process.

She said: “It’s finding out what’s best for you. Some girls love cardio and will happily do an hour in order to cut down, which is fine.

“For me, since I hate cardio, I try to do the bare minimum. You should never force yourself because you will end up hating it and becoming demotivated.

“Also, finding my macros was hard too, everyone’s body works in different way, so I had to find out how much to eat, which was quite difficult at first.

In this Instagram modelled world, where teenagers aspire to look like the perfect fitness models on social media, people like Charlotte find themselves faced with negative comments.

She said: “Even though I get so many positive comments about my body, which I love because it’s so motivating, I do still get the odd few people who will pick it apart and find problems.

“But I use this to motivate myself and you will always get hate no matter what you do, it’s important to realise that so that it doesn’t impact you.

“The best advice I can give to someone just starting out in their weight loss journey is to use weights.

"Start with lighter weights first, obviously, and always ask people who may know more.

“I always reply to my messages about fitness because I love to help people and also follow as many motivating and fitness people as you can; this motivates you and gives you new ideas and new facts you may not have known before.”
