"Say uh... Jen?" Tim asked, reminding himself that Lynda called his wife by that nickname.
"Yeah Lyn?" Lynda asked as she readied herself to start lifting weights.
"Do you mind if we jog for a bit on the treadmills instead?" Tim asked. "I'm just in the mood for a run. You up for it?"
"Sure thing, sounds better than this." Lynda laughed, hopping up to walk beside Tim as they made towards the treadmill.
Tim figured that if they jogged on the treadmill then he wouldn't have to worry about Lynda in Jennifer's life asking him any questions. It would also let him test on others without worrying about anyone staring at him. He didn't like the idea of experimenting on others too much, but it was safer than doing it with himself and causing confusion with every swap.
As the two hopped on, Lynda began talking about her day. It was weird to hear Lynda speak and act as if she was Jennifer, but Tim made sure to just ignore it and nod along. What he was really after was experimentation.
Who would be aware of the changes, just himself or could that change? What about the other setting? Tim noticed the watch had been stuck at 12 the whole time, so what if he changed it? Could people swap with animals or objects? What about age difference or race difference or pregnant people?
There were many questions he had, so he decided to look for a wide range of subjects at the gym.
Near the counter was a late teenaged girl, about 17 or 18 years old who was working the main desk. She had curly blonde hair, a nice body and was dressed professionally. Talking to her was a middle aged latina woman, who had clearly gained some pounds later in life, who was asking the girl rudely about something. Behind them both was a college aged boy who just looked annoyed waiting in line.
Across the gym back by the weights were various people. One such was a 20 something man who was very muscular and very tall, wore only shorts and was likely mixed race or maybe Italian though Tim couldn't tell. By him was a fatter, older man, wearing a wife beater and shorts who was clearly trying to keep up with him without making it obvious. Near them both was a cute asian girl, wearing a nice tank top and short shorts, doing crunches that really emphasized her nice ass as she did so.
Closer to Lynda and himself on the other treadmills showed promise as well. There was a teenaged boy, who didn't look too unhealthy, had curly brown hair and a bit of a belly who was running pretty hard. Across from him was a typical Karen of a woman, whose prime was behind her and whose short blonde hair was tied up in an ugly bun. Near the Karen was a muscular black man, who was just hopping off his treadmill and was wiping off some sweat.
Tim noticed a lot of people, but who did he go with? Should he stick with two to keep things simple or swap whole groups at once? What about an object? There were no animals there but he could try to swap people with an object in the gym. Also, did they have to be there? What if he swapped some gym goers with his friends, work colleagues of celebrities?
Eventually, Tim decided what to do.
