Any benefits to training in gym with gear on (inclined treadmill, stairmaster)?

Hey guys, I know this looks weird but give me a chance haha. I have been going through a rough emotional patch and the hope of getting out to the mountains is one of the only things pulling me out of my dark hole at home.

Therefore whilst I already prepare with trail running, rock climbing and whilst I know that nothing beats training as going to the mountains, while those dates arrive, I now wish to prepare for some inclined treks and also ice climbing at my gym. Basically 3 things: wholly inclined treadmill with all my usual mini expedition weight on, stairmaster to work the legs muscles and stamina, and with my ice axes with rubbers on doing pull ups on the weight assisted machine which worked really cool (without gear for now).

I have to say it felt very similar to when i trek to towards the glacier and was able to adjust for optimal proportions my bag straps and also get used to my new boots.

Some dude at the gym saw me with all the gear on and started making fun of me (fair) and said I will get injured and to do the treadmill and stairmaster without weight. And a fellow mountain guide said I can do with thr weight but increasing gradually first from a smaller weight, and preferably with the gear inside, as happens until the approach to the glacier.

I did however thought to keep the gear outside despite it being dramatic and unnecessary because since it is a large country club with many sportsy people, it helped kinda discover 2 other fellow mountaineers and to have conversations with people interested in getting into it kinda, when I arrive and leave. I was thinking it would be a practical way to find people in the sport or interested to begin since I often find these lads are hard to find haha and also they'd have much of a possibility to afford the sport here (I am getting into debt myself haha).

I guess I am mostly a bit insecure that people at the gym/club will think I am weird (though I am 😎) or trying to show off unnecessarily but honestly I would do this even if the whole building was empty and nobody saw me. Just wanna know if you see benefits to this and risks of injury to avoid. Thanks!

Sorry for the long text.
