Ladies this is for the lower abs which you know is the hardest section to tone. Knee raises can be done at any gym that has a chin-up bar or other bar that supports your weight and from which you can safely hang without falling and injuring yourself. Chin-up bars are also available for home use--they're sold at many stores that carry sporting goods and gym equipment.
See below an example of me showing you how it's done. Enjoy!

Ending Position:
I do three sets of 10 with a 10 second breaks in between.
Get those abs ready ladies, with no excuses and definitely No Apologies!
