Any advise on specific muscles to work to get a bigger and wider butt? Or even some exercises. Hip abduction? Specifically weightlifting.
I second the one-legged bulgarians. My trainer swears by them and he's got an amazing butt.
Box squats are also a great exercise:
Step-ups onto a bench while holding weights or plates are also great. Make sure you keep your foot flat and push up through your heel to isolate the glute.
I wish I could give you some of mine. I'm a guy, but put weight on my ass and thighs just as much as on my gut and love handles.
It's a lot smaller than it was, but it's one of the last places fat is clinging to.
Maybe I can get lipo and airmail it to you - lol
Good luck though. My dad's one of those "no-ass-at-all" types with chicken legs. I guess we've all got our cross to bear...
this is my favorite butt/glute article. good luck!
You could try Potter's routine from his journal: http://caloriecount.about.com/users/eddiepott er/168715.html#comments
Hip dominant exercises (deadlifts, strait leg deadlifts, good mornings, etc) are a good way to go.
