I don't know what it is called but I am assuming it is bar conditioning. My daughter is 4 and at her practice last week the coach gave the girls a challenge on the bars. They had to do a pullover to a front support. Then the girls had to do a belly roll off and hang and then do a chin up pull over again without stopping. Only 2 girls could do it, one being my dd. The coach stopped my daughter after she did 8 in a row without stopping. Should these girls be able to do this or is my dd just strong in the upper body? Is this normal?
