how do you gain weight in a particular part of your body?

can i choose to get more shape in one part?

Yes you can.....what part?

Most likely you can. There are many way of sit-ups, crunches, and all the flex machines.

bottom?

oh yeah cool i like crunches, thats the only one i've done

Do you go to Gym?

Try this an hour or 2 a day.

no just on my carpet

oh i see like twisting my stomach around , but only it it shapes my bottom more, cool

It's gonna sound cheesy....but do millions of but crunches....

will but crunches make my bottom bigger for sure?

Not bigger....lean it out....firm it....do you want them bigger like in muscular?

i want fatter like bigger so my jeans have a nicer bump - mines too small.

Then only 2 ways. 1 better than the other....do weight training or get a bit fatter.....

its sooo tricky , i heard boobs go bigger if i gain weight and i complained about boobs being a problem in tennis, so i didnt wanna eat more i just want a bump like a girl i know that looks great in jeans. maybe weight training i guess then
