Then there’s the famous Gemera that a man who walks down a path where there are inappropriately dressed women is called a rasha, which has also been cited in this discussion. I’d like to add that I’ve seen it pointed out more than once (although unfortunately I’ve forgotten where) that the the Gemora calls the person a rasha just for putting himself in a situation where will be tempted to be oiver on “lo sasuro acharay… eynaychem”, regardless of whether or not he was actually nichshal.
One is not allowed to put himself in a situation that will cause him to be tempted to sin. And anybody who thinks that he can be in a room with women dressed for the gym working out and not see anything inappropriate is only fooling himself.
flatbusher:
“I l know from my own personal experience that some of things said here are just not true, especially concerning how people dress and interact at mixed gyms.”
Did you ask your Rav before your embarking on your “experience”? What did he say?
the plumber:
“Im just saying one line:
The chevra here are hocking about mixed gyms.
Do all of you have your internet blocked?
If not then going to a mixed gym is probably better for your neshama than staying at home”
I wholeheartedly second that.
