Forearm plank

Elbows under the shoulders, forearms parallel, feet together or hip-width.

Forearm plank
  1. 1A straight line from head to heels. Ribs down, glutes lightly on.
  2. 2Push the floor away so the shoulders don't sag.
  3. 3Breathe quietly. Don't hold your breath.

Easy to miss: Hips piked up or dropped so the low back takes the line.

Muscles

Copper on the figure is a prime mover. The softer tone helps.
