Kathy Smith is an American personal trainer who became popular in the 1980s and 1990s for her inspirational workout videos. By selling over 16 million copies of her videos, Smith has created and maintained her position in the fitness industry. Originally hailing from Tucson, Arizona, she is the daughter of an Air Force pilot. She travelled a lot when she was young and grew up in Brazil, Alabama, Hawaii, Texas and Illinois. She lost her parents at a very young age, which motivated her to take up exercising in order to combat depression. She went on to graduate from University of Hawaii with a degree in business administration. Her rough childhood forced her into a life-changing experience as she participated and completed (one of the very few) the Honolulu Marathon. She soon started making fitness videos, which further helped her earn accolades and a place in the Video hall of Fame. She has been an inspiration for millions of women. She still continues to motivate others. Her favourite gym clothes include t-shirts and pants for they allow her to move freely.
