this is weird. title says "should i start going to a gym" and then you just say gyms suck and 90% of the trainers are mentally ******ed and dont know **** about boxing 
go to a gym man, you wont make any progress when all you do is hit the bag a little at home and maybe do some crunches after that. you cant push yourself the way trainers do. and age doesnt matter unless youre 40 or something you still have every chance to become a pro and what not if you are dedicated. but you gotta get somebody to coach you otherwise you are just wasting your time and you pick up a lot of bad habits that the more you train on your own the harder it gets to get rid of.
(unless you are trolling of course, because i still cant believe you actually said what you said earlier about gyms and trainers)
