would be that they allow the girls to wear a sports bra. Any girl with breasts of any size would have a hard time holding on to the treadmill because she would be holding her boobs to suppress extra motion.
Unless quite big conditioning may firm them up and mitigate against bounce. Any suggestions from those that have boobs and run?
I vote for the bras. Exercise only firms the chest muscles beneath the breasts. I don't run, but even hiking and backpacking are uncomfortable without one... and that's coming from a busy lady who typically despises wearing them.
