I'm 24 years old, 5 ft tall and 106 lbs. My butt has always been my best feature, but it def doesn't look like it used to. I want it to be round like it was, it isn't too flat or flabby or anything, its just losing perk. And I want my thighs to slim down and I want to look amazing in a bikini... how can I do this?

Ice-skating did a good job for me, particularly in the bum and legs department. Roller-blading doesn't seem too different, though I've never done it so could be wrong, as long as it's not just casually mooching along in blades like a bored teenager lol.

If you enjoy roller-blading it sounds like a great idea to go for it. Any exercise we actually enjoy is always easier to stick to and you get results without it feeling like a chore.
