I can't tell you how much I LOVE the plank and all the variations of it! I love that it exercises many muscles at the same time. I love that it is isometric, and therefore safe for people with joint damage or arthritis. I love that it can be made easier or harder without any equipment. And, I love that you only have to do it for a minute to get a great workout!
