I won’t lie - since having three children, my pelvic floor has never quite been strong enough to withstand extended bouts of jumping, so when I heard about the benefits of the jack plank exercise, it was music to my ears.
Not only would I be challenging my core and pelvic stability (all the more important as I head towards perimenopause), but I’d also benefit from the cardio element in this "dynamic variation of the traditional plank, which combines core stability with cardiovascular work", as Rowan Clift, training and nutrition specialist at AI-based fitness and lifestyle coaching app Freeletics, says.
