Okay, well, i have a fairly small problem, but it really bothers me. My butt is really big. The rest of my body isnt, and I dont like the way it looks , because whe i stand straight, my lower back curves outwards and my butt sticks out! So my question and request is, any exercises and strengthening ideas to help straighten my lower back and tighten the muscles on my "lower half"? lol. thanks so much!
