13 years old and what to do?

[coheed]

hey im a thirteen year old boy.
im 5 ft. 2 inches
i weigh 126
i am not fat, but i do have some extra baggage
i want to get a flat stomach and chest,
and just look like average thin thirteen year old kid.
i dont want any six pack abs or anything, i just want to look
like a normal 13 year old kid who is at the correct weight and has the correct body type for his age.
any hints on what exercises to do that are best for what im looking for?
also, if anyone answers, can they give me a time range from how long it will take for me to get from where i am now to a normal thirteen year olds body. thank you to anyone who helps

I would stick to bodyweighted exercises at your age.

Things like

Calf Raises

Hamstring Curls

Squats

Crunches

Press-ups

Other upper body exercises could be achieved with resistance bands.

I would stay away from weights at 13, because the stress on your developing bones, might not be good for them.

I would also think about doing 20-30 minutes jogging, or something like that, 3 times a week, just to help yourself.

Timeframe is not easy to say, it takes time, and you just have to be patient, put the effort in, and wait and see what comes.
