the President’s Council on Fitness, Sports, and Nutrition has some standards we can go by (Source): Children – 6-12 years of age should be able to perform between 1-2 pull-ups (i.e. 50th percentile).
16 that is what I think also I am 10 and the most I could do and that should be the same for other kids
as many as he/she can, or as many as you teach her/him
5
a fifteen year old should be able to do atleast 110 sit ups in two minutes.
it depends on how much what your curling up is and also each person is differnt so don't worry about what everyone is doing just do what ur good with
10
100
A 5-year-old should be able to count up to at least 20, but many children can count higher with practice and support from adults.
all five do it
Any where between 25-100.
10-30
A 12 year old should be able to do around 25 pushups in 30 seconds. This is a reasonable answer. Hope I helped you!
