when i did gymnastics, other girls and i would often get ignored. if you mess up a drill or make a mistake one too many times or just aren't doing the skill perfectly, the coaches will often get frustrated and go coach your teammates. like if you're on bars, the coach will kinda pretend you're not there and go talk to your teammate. and then they receive corrections while you're left to figure out how to do something by yourself.
personally, i had trouble tumbling and if i wasn't able to do something, i'd often just stop getting coached. he's just stop watching me and not say a word to me for the rest of practice. once, my coach told me he wouldn't do private lessons with me anymore and i felt completely defeated. so i had to find a coach at another gym to teach me how to tumble. thankfully, this new coach was incredibly nice and nurturing and helped me gain confidence in my tumbling for the first time. another time, i fell on bars at states, and he ignored me until after the next apparatus. but it's conflicting because i spent so much time there and he was like a second parent. but then getting ignored is just hard. who knows.
basically my point is that getting ignored is really the worst punishment. i'd rather get yelled at to point my toes.
