In 7 yrs of gym, and through to Level 10, my dd has cried once during conditioning. Thrown up once too. Both were during summer conditioning, which is admittedly seems to be a little more brutal. I think maybe if it was early on in summer with a bunch of girls new to team, you might expect some tears from several kids. But the whole team? If it were my team I'd keep a good eye out and start watching practices. If it happens again, I'd be very, very worried for those kids' wellbeing.
