Can certain excercuses stunt my growth ?

Im 11 and I'm a black belt in karate

They make me do a lot of workouts there (don't include weights)

I was wondering what exercises stunt my growth

I'm 5'1" and 90lb

The doctor said that I should be over 6'

Do push ups situps crunches and burpies....

Any exercise that includes me using my body only stunt my growth

I have been doing push ups and sit ups since I was 8

I can do a 100 sit ups less than 90 sec (great form)

Is that bad

Like is that too much

I love to do sit ups

Thanks

Btw im a guy
