I’m not much on exercise. We fight with each other like cats and dogs. My Dil2 seems to like to exercise/run for some reason but due to health issues can’t. She however can “Plank.” So she invited all she knows to a 30-Day Plank Challenge; I can do that says I. I saw the chart and thought 20 seconds a day and building to 5 minutes; I will do that. There is even rest days in the 30 day challenge; I like that! Then I tried it!!
