Goal: Complete 5 out of 7 days - two days of rest not consecutively
Day 1. Find your personal starting point. Do the plank for as long as you can (max out). Keep proper form and use a stop watch to time (most phones have the stop watch option). This time is your starting point for the challenge. Rest for a few minutes and then repeat meeting the same time.
Each day increase your time by 10 seconds.
For example: If your first round is 30 seconds, you will repeat and do another 30 second plank. The next day your two rounds will be 40 seconds each etc.
You can see in the diagram above all the muscles the plank works in addition to the abs. It is a great toning exercise!
Today is Day 1! Let me know how it goes! Good luck!
