For simply targeting specific muscle areas, I have found 2 exercises that I love!!!! As you know my general routine is HIIT, elliptical and weights. These are ones I like for problem areas:
Cassey Ho inner thighs 5 minute challenge http://www.youtube.com/watch?v=kJyZhOJ2Tag
and weighted oblique crunches which I found in Jim Stoppani’s 6 week shred

I have done oblique crunches before, but adding weights and holding them overhead while doing it…wow…I am feeling it today!
Just thought I’d share 🙂
