Here's a concept...
Ivy, but in the past she was actually quite the fit little gal. An athletic type who, while not by any means the shining star of her team, was at least notable enough that whatever effort she put in helped a decent bit. She was a real star-studded chick who had the potential to do a lot of things, possibly even go pro if she actually applied herself...
But now? The best way to describe her these days is that she's a homebody. She's gotten grumpy, her butt has gotten more and more flabby, she smells like French fries and sweat, her voice has deepened to the point you can hear her uneven breath, and worst of all?
You probably wouldn't even recognize her, even if she did squeeze into her old team uniform one last time...
Ah yes, the former athlete...
Look at this six pack. She brags to you in her sports underwear, inviting your hand to touch the abs. They are rock-hard and well-defined, clearly a result of rigorous training and full-metal discipline. You almost jump from how sudden it is: you were staring after all, and getting caught red-handed (and probably red-faced) meant you would get jail time for creeping on people. Under normal circumstances - Ivy was anything but normal. She enjoyed the feeling of stares drilling into her perfectly fit carved body. That is what it is all about - showing off. Making people ogle and stare, showing everyone who's the peak of body here.
Ivy was doing athletics semi-professionally, on a level high enough to qualify for national competitions at least - of which she had already first-placed three, with more to come in the future. Then who knows - Olympic fame? World stardom? The sky is the limit when your body is literal perfection.
...you wanna know the thing that broke her? It wasn't the inhumane practice schedule, nor a trauma how you often see in former athletes.
Chicken nuggets. These round, tasty pieces of cut-rate chicken, breaded and fried. Those were the straw that broke the camel's back. Her trainer invited her for a treat at the bar after a particularly productive training session, and with her drinks she got a serving of nuggets - she had never tried them before. She was a health nut, just like her mother; which meant all hell let loose with the first bite and she found herself instantly hooked.
This. This is where her downfall began.
Protein shakes turned into plates of nuggets. [These are also protein, so what's the harm?]
Her regular, nigh-daily training reduced in numbers to a few times, then just one. [I'm so tired and sore... I think I deserve a break today...]
Her post-workout leisure time usually involved taking care of her numerous houseplants, watching videos with puppies, and her guilty pleasure - knitting. Not anymore. An especially filling stuffing session had an unintended effect on her body. It all felt warm and fuzzy, a feeling she used to concentrate into working; a sensation she had not felt since her teens... Ivy soon discovered the wonders of the never-ending stream of movies meant to be something more stimulating than cute cat videos. [I've been going for four hours already... I need to go do something productive... Hahh... five more minutes...]
Needless to say, just a few months of this change in lifestyle were enough to cover her bulging abs with a nice thick layer of flab, for her stamina to drop to an all-time lowest. And right before the qualifications! They decided to try their luck next year and try to spend that time to whip her back into the appropriate shape... Only to receive a paper full of convoluted and eloquent sentences, that, in essence, said "I resign."
What was even more gut-wrenching, the woman submitting the letter of resignation looked just like Ivy, or rather three of them mashed together into a lumpy vaguely human-shaped fatass. Her sports outfit replaced with a baggy black t-shirt and a pair of dolphin shorts way too small for her ass, a mop of overgrown black hair, a pair of glasses on her eyes with bags hanging off of them. She spoke casually, and her voice was the same - except somewhat deeper and huskier and breathier - but it was that moment that the trainer decided she was, after all, a lost cause.
Once back in her apartment, she undressed back into her primordial state - underwear and nothing else. Grabbing a tub of ice cream and a plate of dino nuggies, she plopped into her couch as if doing a water bomb in a pool, to the couch cushions' chagrin.
What are those..? Ohhhh. Oh...
Looking for one of her toys, Ivy stumbled upon an unfamiliar pile of clothes somewhere deep in her closet. Those were her former sportswear. It almost made her think of the good ol' days...
Wouldn't it be fun to squeeze into it one last time?, she thought. Sure, it must be a little tight, but it should still fit!..
Somehow, she managed to worm her way into it. The top squeezed her lungs to the point she could barely breathe, and with the dozens of pounds of fat already weighing down on them she could barely get any oxygen. The bottom was too tight to get past her knees, and if she somehow managed to pull it past her blossoming thighs, her fupa had to be bigger than the entire thing anyway, uncontainable.
And it bursted right off her. In a way, it was what sealed her fate. She was done with that lifestyle, forever. From peak health to the absolute deepest, most depraved pit of degeneracy. From a woman who would conquer the world with her physique to a pathetic excuse of flesh who would not see her 30's.
