A plank step in and out, otherwise known as a plank toe tap, is done in a high plank position and involves tapping one foot at a time out to the side.

This exercise is great because:

It is functional: making the plank dynamic means we can apply that skill to the real-life activities like walking, running and bending in which we need our core to be strong while we move.

It engages the obliques: by adding the lateral movement into the exercise, which a standard plank doesn’t.

It improves stability: your body will have to stay strong as you transfer your weight between your feet.
