Like accomplishing a friggin' side plank! In Jillian Michaels' Six Week Six Pack Abs, she does side planks but she doesn't just do them, she does them and adds another move onto them. I've just been working towards accomplishing HOLDING the side plank for the entire time that she does it. I planned to add the second move when I conquered said basics.
Well, I finally conquered holding my side plank position!!
I guess this means that I have to start the second move during the video tomorrow now!
