Am I just too weak to loosen this bolt?

Hey thereI ride a 2019 ninja 400. Went to go take it out today and I heard something clicking. Upon further inspection it revealed my chain was touching the swing arm. (I don’t know if I cleaned it too aggressively the day before or what).I look up how to fix this issue online and most of it seems really straightforward, until I see that the bolt needs to be bolted to torque.Fuck it, there’s more than once a torque wrench would have benefitted me so I grabbed one, and a 24mm socket to get this done.I can’t loosen it, no matter how hard I try. I’ve put my full body weight into it and it won’t budge. I looked up videos and it doesn’t look like I’m doing anything wrong. It got to the point where I even questioned if I was turning it the right way (went to another bolt on the project bike and no, it wasn’t that).I’m at a loss and I feel defeated. I really don’t want to have to take it into a shop because I can’t loosen a bolt, and if I loosen it, will I even be able to torque it to spec?https://imgur.com/a/IB319ciThe fuckin boltUpdate: MORE LEVERAGE DID IT.Found a bigger wrench and it was just enough to get it done. Going to do my chain adjustment and hope I can torque it back up via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/f9k8sb/am_i_just_too_weak_to_loosen_this_bolt/?utm_source=ifttt
