How long can you hold a plank — and how does it stack up to others in your age group?
That’s the question that was posed on "Fox & Friends" Thursday morning, when co-hosts Brian Kilmeade and Lawrence Jones competed in a plank challenge.
A plank is an isometric move where the person holds a push-up position for a set period of time.
Both held a low plank for well over a minute, exceeding the thresholds for their ages, although Kilmeade held his for a few seconds longer.
