What type of check is advisable to use when sitting?

The elbow check is advisable when sitting as it helps to assess the proper positioning of the arms and elbows while seated, which is an essential aspect of maintaining good posture and ergonomics. This check involves ensuring that your elbows are at a comfortable angle, typically around 90 degrees, and that they are close to your body. This positioning can reduce strain on the shoulders and neck, encouraging better overall posture.

While other types of checks may seem relevant, they do not directly pertain to the specific adjustments needed while seated. For instance, a vision check is more focused on assessing eyesight rather than posture, and a sound check pertains to auditory needs rather than physical positioning. Similarly, a posture check could be considered too broad as it encompasses overall body alignment, but the elbow check specifically addresses the critical aspect of how the arms should be positioned during sitting, making it particularly relevant for ergonomic safety.
