Soooooo I am a little disappointed in me. I did about the same on some (though I think my counting was off a bit. It was early and I had no coffee) or I did a little better. I think I may re-do the test tonight and see if my results are better. If nothing else it will be a 2nd workout for today and after my results I am thinking I need it.
I love planks.. they work your core.. and are just over all great all body work outs
Here is a link to 22 plank variations.
Have a very Fit Day!
