Do you work out at the gym or at home? If at the gym, I suggest that you try the eliptical or that butt machine where you lay on your tummy and lift that thing behind you.
Or try the FIRM videos! Awesome for total body toning and the fanny lifter produces great results! Doesn't get rid of cellulite though but that's hard to get!

But I noticed a difference in that area, like my but seems more lifted, lol.
