Workout plan for 15 year old girl?

i have the same problem. high metabolism isn't a bad thing though, because it keeps you looking skinny and healthy, and attracts guys ;)

try sports. here are some good ones for what you're looking for:

-soccer

-volleyball

-swimming

-track/running

or try these stretches:

-wall sits(for thighs, and helps abs and butt)

-lunges(thighs and butt)

-6-inches(for mainly abs, though it helps with thighs)

-flutter-kicks(mainly abs)

Don't have too many protein shakes. Sometimes they add weight where you don't want it, and the good ones are over-priced. Exercise works better. :)

protein shakes are great if you're trying to gain weight, but you need to be doing some muscle building strength training in order for it to work!

If you want to build up your legs and butt, then go to the gym and work on squats, talk to a trainer who can show you goo form because good form is KEY. Do air squats for a while until you have perfect form, then add weight. you can also use the leg press, adding more weight each week, and you can do squats with the big weight bar that guys use a lot.

always have someone with you to help spot you and make sure your form is good, and always wait a couple of days in between strength training sessions to allow your muscles to build up from the workout

For the body parts you are concerned with the best thing is kettlebell swings.

Make sure to use a kettlebell that weighs at least 15 pounds, the idea is to work the muscles HARD.

Get plenty of protein, shakes and solid food.

Eat lots of chicken, bread and pasta and do squats, running and lunges, but stretch first, Also use moisturiser daily to prevent stretch marks.
