The anti-rotation dead bug adds a rotational challenge (usually via band or cable). For endurance athletes, it’s a potentially high-value trunk control exercise that transfers well to running, cycling, swimming, and triathlon. Endurance sport involves thousands of alternating limb movements. Each step or stroke creates rotational forces that this helps us get better at controlling. I’m demonstrating here alternating hand hold on the band every rep, in reality I’d likely do a set on the same side
