Step by step instructions
Anchor a flat resistance band about a foot above the floor. Lie faceup with toes pointed away from the anchor point. Hold each end of the band, elbows bent 90 degrees, squeezing arms in by sides, palms facing legs. Engage abs and lift legs up to tabletop position with knees bent 90 degrees over hips, keeping spine neutral.
Extend arms and lift head, neck, and shoulder blades off the floor, curling up over the top of ribcage, gazing forward at legs. (Increase intensity by extending legs 45 degrees from the floor). Bend elbows back to 90 degrees and lower head to the floor.
