Q: how to firm and lift butt

A: Two things: you need to lose some fat overall and you need to do some lower-body exercises to build up your butt muscles a bit. The main thing is to lose some extra fat -- if you didn't have extra fat overall you wouldn't have it on your butt either. Unfortunately you can't pick and choose and tell your body to lose the fat ONLY on the butt, but you can lose fat overall and the butt fat will diminish along the way. Read this to learn how to best lose fat.

The second part is to build up your butt muscles a little bit. If you read my fat-loss article and start following a weight training program as suggested there, you'll do some lower-body exercises as part of the program and those will shape your butt a little better. More specifically, squats and lunges are some of the best butt-shapers. If you're not sure how to perform them properly, look on my essential exercises page. Good luck!
