Not to be rude here, but i'm not going to jump on the band wagon...
I understand your goals, and I think I'm in a similar situation as you where you look "good" but not "great"... you're at a point where a solid full body workout will tighten up your abs and butt, giving you the look you're going for. If you get your workout in line and you're still not seeing the results you want, the only other place to look is your diet. Try a very slight calorie deficit to burn a little excess fat and you'll have that hot bubble look you're shooting for...
P.S. please send me pics of the completed "bubble" look
