After dark. I love the vibe at midnight or later at gym. All old school meat heads and maniacs like me who enjoy power lifting late night. It's only time I can be yelling at grunting and covered in chalk and sweat and bloody knees
I I'm not saying yelling and carrying about to make a scene is acceptable. any other time it's obnoxious. I give you it a green light only when lifting like a caveman.
