Step by step instructions
Anchor a flat resistance band about a foot above the floor. Kneel facing anchor point, knees hip-width apart and toes pointed. Hold each end of the band, arms extended low in front of body.
Hinge back at knees as far as possible, keeping spine neutral and abs tight, bending elbows 90 degrees out to the sides of shoulders, and squeezing shoulder blades back and together (imagine trying to grasp a pencil between them).
