When performing the army crawl, which kinetic chain checkpoint commonly needs correction?

Shoulders

LPHC

When performing the army crawl, the LPHC, or Lumbo-Pelvic-Hip Complex, is often the kinetic chain checkpoint that requires the most attention and potential correction. In this exercise, maintaining a stable and aligned LPHC is crucial for proper movement mechanics and to prevent injury.

A neutral spine position must be achieved to ensure that the pelvis and lower back are properly aligned during the crawl. If the LPHC is not stabilized, it can lead to improper movement patterns, compensation, and overexertion of other body parts, particularly the shoulders and legs.

Attention to the LPHC helps enhance overall performance of the army crawl, ensuring that the individual benefits from the exercise while also minimizing the risk of strain or injury to the lower back and hips.
