Sure they can, I've had one since 2nd or 3rd grade. If you do 20-30 push ups a day, this works out your abs and biceps, and if you do the plank position, this will get your arms and abs pretty strong.
An 11 year old has exactly the same amount of muscles as an adult. You can have whatever size "pack" you want (although an odd number pack may appear slightly strange).

no i am a children pediatric doctor. it is impossible for a 11 and up year old girl to have a six pack. by the age of 9 or ten girls will lose the ability to have a full six pack girls can only have a 2 to 4 pack. to get them they would have to do 50 yo 100 sit ups a day along with push ups. some people say that running, boating or swimming will improve your six pack but they don't. they only work on your arms and legs. it is impossible to get a full sick pack at age 11 and up
Yes yu can but gotta start doing crunches for a year or two and work out alot! porbably not. but is possible!I AM 13 and i have 8 pack!
not sit-upsboxing is a good one
I suppose 11, 12 years would do the trick.
Six and a half
you should be atleast 10 or 11. As long as your responsible if your 10 or 11 then that should do.
Body weight is relevant to height. So an 11 year old that is taller than average would likely weigh more. However, 77pounds would be a good average weight for an 11 year old. So 6 stone (88pounds) is slightly on the heavy side for an average height 11 year old.
I'm eleven and i have a pretty toned six pack. I'm not sure when I started forming muscle but I know it's because I play sports especially baseball daily.You don't just get muscle even a six pack from just sports. If you want a 4 pack then the least time it could take if you work out and eat right is a month. After about a month of being active and eating right you will probably see the results. But if you want a toned six pack that can take maybe 3 months at the least. I hope I helped.
ask another eleven year old.
it should roughly be around six stone and a half but it really doesn't matter
