I am not a member of Pinterest. I don't ever plan on "pinning" things there. Good heavens, I don't have time for that. My copy button on the computer works just fine and so does my printer. Anyway, I searched the Fitness page looking for some good ideas. I found three and did a little ab experiment this week.
These were my routines:
I did one routine each day for three days in a row in the order seen. I did not really like the Core Challenge. I know planks are an amazing exercise, but I thought this routine had too many planks. It was good, but not for me. I liked the variety of the first one...abs, jumping, etc. I actually went through it three times because I did not feel like my abs were getting a good workout. Finally, I did the 300 Abs and I declare it the winner. My abs hurt when I was finished. I only did it one time and that was plenty. I also did each exercise slowly to ensure I was really working each ab muscle.
My abs are getting the day off tomorrow, but I will be coming back to this on Saturday!
