People can wear what they want at the gym as long as you're not showing nudity .
But i've seen a few of those videos and
1. The women are looking for attention
2. The men in the background never consented to be filmed
3. They're trying to make the men look 'creepy', and they need to stop shaming these men.
4. They want views and followers for their insta /tiktoks . It's actually really pathetic and annoying

.
When was it a crime to glance at someone at the gym, it's a public space ... and everyone is in the same boat in their own zone working out. From what i've seen , these men offer to help these women with the equipment. And they also ask if they've finished using another machine?? , which is just good manners imo . It's all drama over nothing.
