Which posture might signal that a client is not maintaining alignment in Pilates?

Excessive arching in the lower back is a clear indication that a client is not maintaining proper alignment in Pilates. In Pilates, maintaining neutral spine alignment is essential for both stability and safety during exercises. An excessive arch creates a hyperlordotic posture, which can lead to tension in the lower back and potentially cause injuries. This alignment issue suggests that the core muscles may not be adequately engaged, which is crucial for supporting the lumbar region and ensuring efficient movement patterns throughout the body.

In contrast, a straightened back with engaged arms, broadening of the shoulders and pelvis, or even distribution of weight between the legs generally reflects better alignment. These postures indicate that the client is properly activating their muscles and maintaining a more balanced stance, which is fundamental in Pilates for achieving optimal results.
