i'll be 70 years old this year. i have had no formal gymnastics training and i didn't play any high school sports. i did start weight training in my teenage years and competed in the 1977 state of michigan powerlifting meet in the 198# class where i came in dead last with lifts of a 410 squat, 340 bench press and a 500 deadlift. i also didn't use any PEDs, never have, and didn't use knee wraps or a supersuit/ supershirt; so basically really clean lifts. after that meet, i realized that that sport wasn't for me and went on to other pursuits. i have done various other forms of training such as martial arts, some distance running and bicycling without having any particularly outstanding achievements. that being said, i stiil like to challenge myself, and if i can do something, you probably can too, as long as you're consistent. if you're near my age bracket and haven't been exercising, start out with easy things you can do and don't hurt yourself jumping into whatever it is i'm doing.
