Think of “functionality” as a cloud term for enhanced movement, coordination, and balance. Plank trains the abdominals for stabilizing the body no matter what you are doing. And when you know how to engage them correctly, you work more efficiently.
No matter what you do – dancing, running, biking, hiking, climbing, or swimming – a strong core is so beneficial to functional movement. This is because through planks the body learns how to fire all those muscles simultaneously.
