EDITOR'S NOTE: Every Sunday we will be featuring a new bodyweight exercise video from physical therapist Ben Musholt, author of the Mad Skills Exercise Encyclopedia. Ben has a diverse movement background, spanning board sports, martial arts, parkour, and gymnastics. Get watching and get moving!


In this video, Ben demonstrates four core stability exercises from the plank family. Plank exercises are made more difficult through varying how many points of contact are on the ground, as well as by adding a dynamic component to the movement. Ben mixes up both these elements to create four different dynamic plank variations. The exercises you will see include plank splits, side planks, plank side crunches, and side plank leg swings.
