You look great! I am right there with you on trying to lose the last 5-10, sucks!

I have had great response to weighted hanging leg raise/crunch. I put my arms through straps, let legs all the way down til I'm stretched out, then pull my knees all the way to my elbows. I started body weight 3 x 10 and now can do it with 20 lbs strapped to my feet. From my upper thighs all the way to my serratus is smoke after these. Can't get much more of a complete stretch to max contraction than these. Once you get tired trying hold your knees to your elbows is intense.
