I work out in an only women’s gym, it gets very warm so I do not dress in a lot of clothing. Only women are at this gym, so it is muttar for me in order to be comfortable. But very often I am on the treadmill and this lovely chosheva lady gets on the treadmill next to me and is saying Tehillim. I asked her if it was okay for her to daven while I am not tznius, she didn’t know the answer. I do not daven on the treadmill because I personally don’t feel it is the proper atmosphere with ladies dressed not tznius and the TV on everywhere. But I don’t know the actual halacha and if anyone knows, can they post it here?
