Lithe, slender, and stronger

Jackie was stunned by the vision in the mirror before her. All of the flab had vanished from her arms and legs, and been replaced with tight, sleek muscles. She wasn't built like a bodybuilder, but the way her calves, thighs, and butt popped, you knew that she was some sort of athlete.

But why didn't she look like a bodybuilder? She tried flexing a bicep in the mirror, and an aesthetic bump formed in her arm. The skin was smooth and tight around it. Maybe she needed to use more weight? Or maybe it had something to do with the fact that she didn't feel much resistance in her exercises? Within a few minutes, she would master whatever new weight she was handling. She'd have to keep an eye on it. Looking at her appearance the way it was now, she decided it was the perfect blend of fit and slender.

Amazingly, it wasn't just her body tone that had changed; even her limbs looked longer! She turned sideways and reached down to her toes. "Too easy," she thought. She tried standing, casually lifting one leg straight up to vertical without any aid, and then pushed on further, pressing on her leg to do a full 270 degrees. "Well that certainly makes it look longer!" she thought, as she rested on her own pose, examining the shape of her leg, leading to a very pleasing, firm butt and pussy lips.

However, she did see that her tummy still had an unacceptable amount of fat, which she pinched between her fingers. It was a complete disgrace compared to the rest of her. For the first time in years, she left her computer off, and got to work immediately. "Why didn't I do this sooner?" she thought.

Hooking her feet underneath her mattress, she lay down flat and began to do crunches. Oh yeah, she was definitely taller now; her head was bumping into a large dresser against the wall when it never would have before. Squatting down, she got her hands on either side of it and grunted. With a cry of surprise, the whole thing rose smoothly into the air! There she was, the spitting image of a fit supermodel, holding a fully loaded dresser casually in her bedroom.

She placed it back down and out of the way. There would be time to explore her new strength later. Going back into a lying position with her feet under the box frame of her bed, she began her sit ups at a breakneck pace. No need to hold back now. When she pushed herself as far as she thought she could go, a slight sheen of sweat covering her body, she would get up and look at herself in the mirror. Every single trip to and from the mirror was a sight to behold. Within seconds, she recaptured her breath and stopped sweating. It was hard to see at first, but she realized that there was noticeable improvement after every single set. Oh how she laughed! She could take photos of herself as if it were a time lapse slideshow, except it took her an hour to do what other people did in a year!

As her torso tightened and a subtle six pack developed, she noticed that it also emphasized her breasts. The contrast between her pebbled abs and her perky tits was a sight to behold. She was never particularly large, but they fit in her hand nicely, and now definitely had some nice pop to them. Pinching one of her perfume pink, jutting nipples, she wished she were larger, but there was nothing she could do about that, could she? Anyway, maybe Marie would know how to dress them up.

The next set had a surprise for her: as she took her position once again and smoothly did another sit up, she found that the counterweight was no longer strong enough to hold her down! The entire bed rose off the floor, supported by nothing but her delicate feet! Quickly, she let it back down before everything came crashing to the floor. Then she lifted her legs again, and the whole thing rose effortlessly. Smiling, she now began doing leg lifts with the entire bed frame creaking to her rhythm.

She had started the day as just an average looking student. By 8PM flat, now she had the body of a supermodel with inhuman stamina and strength to boot. How far could she go, she wondered, as she jumped down the entire flight of stairs, landing lightly on her feet as she went to fetch dinner.
