One Canadian woman's before-and-after figure photos would make most people swear she'd had butt implants — but in fact, she did it all naturally. 

Abby Pollock from Toronto looks painfully thin in photos from five years ago — and she was painfully thin, suffering from an eating disorder and sticking to an unhealthily restrictive diet.

Now, though, the 23-year-old looks slim and strong, and has a round, firm-looking backside that would be right at home in the Kardashian households.

Wow! Abby Pollock from Toronto has shown off her amazing transformation on Instagram

Way to go! She said she now weighs over 150lbs — something that would have horrified her before, but she is OK with now because she has built so much muscles

Come a long way: The 23-year-old used to struggle with an eating disorder

Far: She ate 900 to 1,000 calories a day and at her worst only consumed two salads and a protein shake while she was up

Amazing: Now she eats 1,700 calories and has a healthy workout plan

Amazingly, Abby did it all the natural way, changing her diet and her fitness routine and not stepping near a plastic surgeon's office.

She had a long way to come. As a freshman in college in 2012, Abby was 20lbs. underweight. According to Cosmopolitan.com, she consumed 900 to 1,000 calories a day, whittling her food options down to an entirely raw vegan diet. She also struggled with bulimia. 

'Eating 1,000 calories a day took constant willpower. I was physically drained from eating so little, I was mentally drained from obsessing over such a trivial part of my life,' she explained on Instagram.

At her most restrictive point, she'd eat two salads and a green smoothie a day — plus some more raw veggies if she felt like she was going to pass out from hunger. 

In 2013, she got help, enlisting the assistance of a holistic nutritionist and personal trainer. She said: 'I decided I was done playing victim, done breaking myself down.'

She has over 260,000 Instagram followers who are obsessed with her fitness posts

So fucused: She works out four days a week for an hour a day

She pays attention to different areas during each workout to keep her body muscular

Workout: Squats, she said, are not the key to a better butt; she favors barbell hip thrusts, the abduction machine, and banded leg press variations

She increased her diet to 1,700 calories a day, eating healthy food. Her workouts gradually changes, too. Eventually, she was doing heavy lifting, which sparked a huge transformation.

The 5'7" fitness fan weights 152bs, most of which is clearly muscle. She admitted: 'I used to worry when I got above 125 lbs and really felt like I’d let myself go if I got over 135 lbs. But here I am, in my opinion, more athletic than ever and I weigh OVER 150 LBS!!!'

Her once straight, boyish figure turned into an hourglass, and her butt grew and raised up. She says a variety of exercises helped get it that way.

'Doing just squats will not build a booty,' she explained, adding that she favors barbell hip thrusts, the abduction machine, and banded leg press variations.

Changes: She used a nutritionist and physical trainer to help her get healthy when she was at her smallest

Abby struggled with bulimia and would eat veggies only when she felt like she might faint

She now eats more and is heavier but has a much better body — and is, of course, much healthier

She said: 'I find a lot of people neglect or don't know how to properly engage their gluteus medius, which results in a bigger but not rounder booty.'

She doesn't work out every day, either. She does an hour of exercising four days a week, focusing on different areas of the body each time.

She also shares her progress online, as well as tips for followers who want to make their butts look just like hers.

'Building a rounder rear requires much more than just doing squats,' she shared once. 'Turns out your glutes are made of three main muscle groups: gluteus maximus, gluteus medius, and gluteus mininus. 

'To shape that round Georgia Peach you need to focus on engaging and building all these muscle groups,' she went on. 'I find a lot of people neglect or don't know how to properly engage their gluteus medius, which results in a bigger but not rounder booty.'
