What is the ruling on women practicing aerobics among themselves if the clothing is tight?

The default ruling is that it is permissible for a woman to engage in sports among other women, provided she adheres to the Islamic guidelines. It is preferable for her to limit her exercise to within her home. It is not permissible for a woman to wear tight or transparent clothing that describes the body in front of other women or her mahrams, except for her husband, because she would be setting a bad example. She must cover her awrah from everyone except her husband. A severe warning has been mentioned for those who wear tight or transparent clothing.
