Plank Up-Down: how to do it and form tips

Plank variant that adds shoulder + tricep work. Alternate from forearms to hands and back without breaking the plank line.

Form tips

  1. Squeeze your glutes — body stays a straight line throughout.
  2. Move one arm at a time; keep hips as level as possible.
  3. Place hands directly under shoulders when in the high position.
