love it. it is a good stress reliever for me. reporter: 37-year-old barbie thomas started to compete in 2003. i said what the heck. i m going to go for it. reporter: that determination might surprise you and even inspire. get a trainer real quick to help with my next exercise. reporter: barbie s routine is different than most. i was 2 1/2, and i got into a transformer. the electricity went in through my hands and out through my legs. reporter: doctors had to amputate her arms and didn t think she would survive. i think god had a different plan for me and spared my life. reporter: she is now a fitness competitor on the national level. i got a lot of funny looks the first time i competed. reporter: her trophies prove her success. she does most everything with her feet, including texting, driving and working out. i have those days, too, that i don t want to go to the gym. reporter: her faith, a constant reminder to never give up.
