My wife and I have started training a few months ago

Hey similar worlds family. I wanted to find out does similar worlds have a fitness or gym community? My wife and I have been training for a few months (she's doing alot better than me lol) and my wife has started to hit a plateau. She mainly trains her glutes and legs and I mostly train my upper body coz I hate leg day haha but I wanted to find out if there are people with knowledge of that because we've tried googling and ai but it hasn't really been helpful.

Id like basic tips but for her it'd be more niche like for example her glutes have grown alot but she's struggling with the upper outer part and I'm clueless I tried helping and some of the advice I searched has helped me but I thought it'd be nice to have a community to ask and speak about these things.

So if there is something like that please direct me there.
