Hey other UMers.  I found a program that works great for your waistline without having you hit the floor and do the dreaded crunches.  Honestly, these exercises work incredibly well.  The downside is that they do cost a few dollars to get.

The series is by a dude named Matt Furey (really, no kidding) and it's called Combat Abs (along with his program Combat Conditioning - which I also have and recommend, but if you have knee issues, check with your doctor or chiro for the best of the squats that will be good for you..).  Combat Abs is a TOTAL winner.  What Furey calls the Magnificent Seven will have your waist and core in shape in no time AND you will absolutely see a benefit in your measurements!

I encourage anyone and everyone to check them out. 

Peace!
Phillip
