Prone YTI
- Keep your chin tucked and head in line with the rest of your spine.
- Tuck your tailbone under and use your abs to keep your ribs pulled down.
- With your thumbs up, squeeze your shoulder blades together as you move your arms in the YTI motion.
- Don’t jut your chin out, shrug your shoulders, allow your shoulders to roll forward, or arch your lower back.
