In the past few years, it's become apparent that sitting at our desks all day every day, followed by hours of sitting on the couch while we binge-watch "The Great British Baking Show" is killing us. But what we didn't know is that it's killing us butt first.
It's called dead butt syndrome (well officially it's called gluteal tendinopathy). It affects the gluteus medius and minimus, which are smaller muscles than the more well-known gluteus maximus. (The gluteus medius is attached to the upper portion of the pelvis and to the top of the femur, while the gluteus minimus is attached to the outer surface of the pelvis and to the head of the femur.) The two work with the gluteus maximus to form your buttocks, so when the gluteus minimus and medius are weak, it puts strain and pressure on other muscles in the hip area, including the hip flexors at the front of your pelvis, to pick up your butt's slack.
