In Friday core class we did a new kind of plank. We split into pairs, and each pair had 1 band.

Person 1 was on elbows and knees, with the center of the band in a bicep curl position. That person was the “anchor”.

The person working out held the band handles in a plank position.

First you hold the plank for 30 sec count. Then you walk backwards in plank on your toes and hands with the handles still gripped and get as much resistance as you can and hold for 30 more seconds. Then you walk back toward the partner and drop.

Switch partners until you’ve each done 2 sets.

2010 goal update: 4270 crunches, 93 minutes of plank remaining.
