This is a quote from The Best Body Ever:
"If you’re on a cardio machine, don’t slouch, or hang on to the equipment for support or assistance. I see slouching all the time on the Stairmaster and treadmill, and that isn’t good for your back. Stand up straight. And if you find that you’re tired and are starting to slouch and need to hang on for support, stop what you’re doing and take a short break. If you’re still tired when you get back on, maybe you need to wait and build up to that level of exercise without having the need for support."
Canada.com has a great article on the benefits and steps to better posture when working out as well.
I didn't comment to this woman how she was doing herself a disservice because I was worried about her reaction. Personally, I'd be embarassed, but I would appreciate the advice and research it when I got home from the gym. Would you have commented?
