so im trying out for competitive cheerleading in 2 months and in cheerleading they do stunts, tumbling , and a dance at the end , all in 2 minutes and 30 seconds . and i know 2 minutes and 30 doesn't sound long , but when your doing non stop back tucks & back handsprings , stunts and a dance , it's feels like forever . and ive known a few girls who have puked on the mat during their routine , and it freaks me out bc i HATE puking . and im so scared that ill puke . does anybody know something i could do to prevent this ?
