We all know that sitting hunched over a computer or phone wreaks havoc on our posture, leading to stiff, achy joints and rounded shoulders. Over time, this can significantly reduce upper-body mobility— a problem I frequently see in my personal training clients, especially those with desk jobs.

To counteract this, I often take them back to basics, focusing on dynamic stretches to improve flexibility and range of motion. This helps them get the most out of their upper-body workouts and improves their posture.
