Hey guys,
New on here (forgot I had a username). My names Ty, and I am looking to get into the sport. I realize there's so much to learn, and people probably come on here making similar post's alot, so I apologize in advance for being "that guy"

. Anyways, I am looking into getting into some moderate trails. Nothing crazy with like huge drop offs and jumps and whatnot. I am mainly doing this for exercise and fun, because I need both in order for the exercise thing to happen

haha. I have some fun trails about 5 miles from my house so I am planning on riding there, hittin the trails, then riding back. I am basically getting out of motocross and getting into this. I have done it a few times on a bike not meant for it, and it was a blast...but painful
So here's my question (finally

). What should I be looking for while shopping for a bike? I want a hardtail in the 4-500 dollar range give or take. I would love to buy new, but buying used is probably going to be my best bet. I am 6 foot and weigh 220 lbs (plan to get to 190 eventually).
I just need to know what brands to look for, what specs to look for, and all that jazz. I am not completely new to bike's, but I am definitely not up to par with everything. If you could lead me in the right direction to find a nice bike for a guy built like me that would be fantastic!
Thanks a ton,
Ty
