Someone who is capable of being physically active, sexy as hell, witty, and charming in the same moment. A person who looks amazing and has fun while sweating. Must be the person who you envy at the gym and someone who makes exercise fun!

The term was coined for Liz Wexler in New York City in 2007 by two of her friends whom were always in awe of how amazing she looked while working out and how passionate she is about physical fitness.
