I came across info about planks for people over 60. My 63-year-old dad’s stuck to a daily plank routine for a year, and last week he carried a heavy stack of my old lesson plans up three flights of stairs without complaining about his back. I can barely hold a plank for 15 seconds before my shoulders give out. The piece said solid form boosts functional strength, making daily tasks easier. I might try one tonight. Alone, of course. No way I’d let anyone see me huffing through it.
