She's a nerdy pony who just so happens to be VERY buff and athletic XD
Raised by a Pegasus mother who was a star athlete and an earth pony father who was a teacher, she grew up getting an education from the best of both worlds, as she learned how to keep both her mind and body to work at their peak.
She grew up to enjoy traits of both athletic and nerdy types can enjoy. She's just as much willing to go hit the gym and do some squats and lifting, as she is to sit down and binge watch a bunch of classic sci-fi shows :3
Despite this, she still had trouble in her high school years. A lot of sporty ponies thought she was too much of a nerd for their liking, and a lot of nerdy ponies were worried that she was gonna be too rough on them. It doesn't help that under that buff body, she's actually very shy and nervous X3
