You’ve heard of CBS and maybe IBS. But do you know about DBS? It stands for “Dead Butt Syndrome.” The medical terminology is gluteus medius tendinopathy or gluteal amnesia. Basically, it means your glutes aren’t working properly after long periods of inactivity. Your butt forgets how to do its job.

How does this happen? When you’re sitting down, your hip flexors tighten and your glutes stretch. If you aren’t regularly stretching out your hip flexors, you could develop Dead Butt Syndrome. People who are glued to their desks and gamers who spend hours sitting at their screen are at risk of developing DBS.

What are the symptoms? According to Tom’s Guide, lower back or hip pain; knee and ankle pain; and shooting pain down your legs can all be signs of Dead Butt Syndrome. If you have numbness in your glutes after a few hours of sitting and it subsides within a few minutes, you’re probably fine. The numbness associated with DBS won’t disappear as quickly, or at all.

What can you do to prevent DBS? First of all, break up the time you spend sitting. Take a walk around the office every 45 minutes. Also, do exercises like squats, glute bridges, deadlifts, and step-ups to stretch your hips and strengthen your glutes. If anyone at work gives you funny looks, just tell them you’re committed to the fight against Dead Butt Syndrome.
