The program is 3 days of exercises, followed by a rest day. Each day is a little harder than the previous. By Day 11, I could barely finish. So after a day of rest on Day 12, I decided that I would repeat Day 9, 10, and 11. I did Day 9 on Friday, and yesterday I justified skipping a day since I had to run 9 miles for marathon training. Now I find myself at the crossroads of procrastination. I am telling myself right now that as soon as I finish and publish this blog that I will go to my bedroom at complete Day 10.
I starting running in 2009 using the Couch to 5k program. I read somewhere that if a week was really hard that it was best to repeat a week rather than move on. I repeated many weeks and took extra rest days between run days. But I finished it. And I've run 3 half marathons to date. So I thought the same method could be applied to 30 Day Abs. My journey, at my own pace.
If anyone else is considering doing this challenge, I highly recommend buying an ab mat. I bought one for $20 on Amazon: http://www.amazon.com/Workouts-Machines-Equipment-Trainer-Exerciser/product-reviews/B00BBLDN56?pageNumber=2. It's basically a little curved mat that supports the small of your back. It also helps you get a better range of motion and do the exercises more effectively.
Here's a similar 30 Day Abs program, the one I saw circulating on Facebook:
