Her powers are genetic in nature.
Limitless Potential: She has an unlimited genetic potential for physical improvement. While humans would only be able to achieve certain physical milestones regardless of training, Lisa doesn't have that restriction. Be it that her muscles are denser than other peoples, her bones are stronger, or whatever other factors her body decides to use to adapt, there just isn't any known limit to how strong, fast, tough, agile, etc… she can be. The drawback, of course, is that she has to actually train that hard to get there. That means hours in the gym, eating way more than other people, and being very disciplined. It also means that if she took six months off and started eating junk food, her superhuman abilities would go away very, very quickly.
Mental Resistance: Lisa doesn't currently have any real psychic abilities, but she does have a natural resistance to mental attacks, mind control, emotional control, etc… This is likely a side effect of her genetic makeup. She may have the potential to discover future mental powers, but so far, this is a mostly unexplored area.
Inexhaustible: Lisa doesn't need to sleep. Period. She also recovers from tiredness nearly instantly. This comes into play, unsurprisingly, mostly in her training. Most people can work out for an hour or two, tops. She can, if she wants to, work out all day for a month and reap the benefits of the intense training. This is useful because in order to increase her physical abilities into superhuman levels, she has to workout at an intensity that is superhuman.
Combat: Lisa has trained in martial arts since she was extremely young. She knows how to handle herself in a fight.
Dancing: Lisa is a pretty decent dancer. She knows some formal dances as well as the ones that adults would refer to as flailing around the dance floor.
Gaming: Lisa loves games. Video games, board games, whatever. She's pretty good at them, too.
Pain Tolerance: Lisa can take a bit more punishment than most people without showing any outward pain. This is mostly a result of her years of martial arts experience.
Sports: Lisa is well-versed in most sports and is pretty good at picking up whatever sport is being played.
Training: Lisa, because of her upbringing, knows a lot about physical training. She knows enough to give pointers to others if asked and how best to get results. She uses this to help develop her own powers.
Lisa was born to a family that was said to have 'good genetics' for athletic accomplishments. Her parents had both been Division 1 college sports stars and her father had made it up to AAA baseball before settling down with his family. So it was no surprise that their eldest daughter, Lisa, showed a certain amount of physical aptitude. The family lived in Denver, Colorado, and her parents saw to her early training. She started taking martial arts classes at an extremely young age and her father determined that she was old enough to start learning how to use weights while still in elementary school. This was quite abnormal, but he pointed out that his family had all started serious athletic training while they were in their single digits in age.
It turned out that the family genetics were quite abnormal and had finally reached some sort of superhuman breaking point when mixed with some latent genetic markers on her mother's side. The girl didn't seem to need to sleep and could workout harder and longer than anybody in her family could imagine a child (or adult) sustaining. Yet her physical abilities grew by leaps and bounds. Her parents, realizing something was going on, invested heavily in their home gym to the point it was capable of replacing the commercial gym she had been going to in order to shield their daughter from the questions she was starting to raise. She was outlifting and outrunning her father by the time she was eight and had already received the talk about keeping that level of strength under her hat from the public. She has a couple younger sisters and a younger brother as well. So far, none of them have shown any abilities. Word eventually got around and her family was contacted about a school for students like her. They agreed to the terms and the girl was sent off to school at Coral Springs High.
