Thanks. That’s what I thought the plank drag would be, but there’s also plank drags where you walk forward with your plank and pull a sandbag. Didn’t know if there was a version of that one with a dumbbell. my assumption on the fast feet dumbbell catches that you take a light dumbbell and carefully toss it hand to hand while you’re tapping your feet, but unclear. that being said, I know it doesn’t 100% matter, just keep moving. But I am always curious as to what Nicole was intending.
