OK! So here’s the deal: do 1 minute of plank for the date. So on January 1, I did one minute of plank. Today is the second so I did 2 minute of plank. And so on. You can break it up during the day if you have to. (I did 4 rounds of 30 seconds with 15 seconds of rest in between.)

Here’s a little video to show you the proper way to do a plank:

Good luck!
