Movement media
The written setup, cues, and alternatives remain the current technique reference while the tutorial is produced.
Accessible movement summary
Place the forearms on the floor with elbows beneath the shoulders and extend the legs behind you. Press the forearms down, squeeze the glutes, and align the head, ribs, pelvis, and heels. Breathe quietly while holding only as long as the aligned position remains unchanged. Lower the knees to end the set before the lower back sags or the shoulders become painful.
Key cue: Pull elbows gently toward your toes.
