Yes, there is risk everywhere. Kids get hurt everywhere.
Had a gymnast, a few years ago, get a concussion in gym class at school - out for a year.
So far this year, we have had 5 gymnasts injured in cheerleading (a BHS leading to a broken elbow, 2 ankle injuries requiring 6-8 weeks in a boot, a torn meniscus, and a dislocated knee) ... and the competition cheer season hasn't even started yet, so this was all for sideline cheer practices.
We have had a girl injure her knee going upstairs at school ... another one that tripped over a curb and sprained her wrist ... and, if I heard correctly, one girl broke her foot getting off the school bus!
Oh, and a girl on pre-team a few years ago broke her wrist roller skating ... but her mom was clueless and sent her to practice 3 days later saying she was "fine." After seeing her on beam (after bars), I called her over, and then called her mom and MADE her take her to be examined. I could do this because she is YG's little step-sister.
The nearest trampoline park is 40 minutes away, so I don't worry too much about it (even though I don't personally like them).
