Planking, it's actually a workout

I love this picture, planks are a very good workout.  Planks I hate them, but I love them.  I dread doing them in every Jillian workout.  You do a lot of plank work in her DVD's.  I came across this challenge on Pinterest not too long ago, and had to try it:

I knew that I could at least do 1 minute already because of the workouts that I have been doing.  I started out at 2 min for the first 4 days.  The 5th and 6th day I did 3 min. Day 7: 3 min 15 seconds.  Day 8: 3 min 30 seconds. Day 9: 3 min 45 seconds.  Day 10: 4 min 5 seconds.  It is hard, I wanted to get 5 min, but my arms wouldn't hold.  They were shaking so bad, and my core felt like it wanted to split in half.  I still feel very accomplished, and will work towards that 5 min!
