I swear Gyms dont have age restrictions, but i could be wrong of course!

Dont practice at home till you learn the basics from somone who knows what they are doing aka a coach.
it doesnt matter if you cant go down there every week, hell if you only go twice in your entire life thats fine, but you need to learn the basics properly, otherwise your never going to be able to box!

as a general rule the only thing i try to pick up from pro's is fight stratergies or how to make openings, because evry fighter has a malfunction, or something they do wrong. you want to be origional, not somone else.

good luck and if you could provide Dave_Bandit and me with some basic statistics of your body we might be able to help you out
