i say yes and no,
it's like a constant addiction though. you stop and then wanna start up again it's a mental thing for me. i guess i am a softy and care about my health and thats the reason i never went balls out with anything.
i started them early enough but i wish i knew more back then,i wasted many years tinkering with crap that was a waste of time.
if i could go back i would have probably hit it harder and got super jacked and then easied my way off over the years, it's easier to maintain the muscle with less than build it in the first place.
