How to perform

  1. Set up face down with forearms on floor, elbows under shoulders
  2. Extend legs straight, toes on floor, feet hip-width apart
  3. Form a straight line from head to heels; keep neck neutral, chin slightly tucked
  4. Brace core: pull belly button toward spine; ribs down
  5. Squeeze glutes and quads; lightly tuck pelvis to avoid low-back arch
  6. Press forearms and toes into the floor; round upper back slightly to engage shoulders
  7. Breathe steadily; hold 10–30 seconds to start, stop if form slips
  8. Avoid hips sagging or piking; regress to knees if needed, progress with longer holds or one-leg lifts
