On Saturday I started a Plank challenge that was posted on Facebook:
It was to start with a 20 second Plank and work up to a 5 minute Plank in 30 days. A few of us have added a challenge to it to see if we can take it a step further.
The standard Plank we are doing is holding the top or high end of a push-up for the set time.
Our challenge Plank is holding the bottom end of the push-up without touching the ground for at least the set time.
So far here is my info on it:
Saturday: Standard Plank 20 sec / Challenge Plank 30 sec
Sunday: Standard Plank 20 sec / Challenge Plank 52 sec
Monday: Standard Plank 30 sec / Challenge Plank 60 sec
