Throw reality out the window for a second and entertain a hypothetical. Imagine you can only do one exercise for the rest of your life. If you had to choose a single exercise to do for the rest of your life, right here today, what would it be? It’s a popular question with a divergent set of answers depending on who’s being asked, and for the most part I see where everyone’s coming from.
If you ask the AARP, it’s the plank, which is easy on the joints, involves every body part, strengthens the core which can help prevent falls, is very safe for seniors (the intended audience of AARP), and you can do them anywhere without equipment. I have no fault with the plank.
