When you’re inactive for long periods—think sitting at your desk, commuting, or watching TV for hours—the muscles that move and stabilize your hips can get tight (or, more technically, short). A large muscle group called the hip flexors—which originate in your low back and cross over your hips and are largely responsible for hip flexion (any knee-to-chest movement)—can tighten and constrict when they aren’t stretched, strengthen, and utilized (or moved) frequently enough. When the hips get tight and neglected, you can actually develop low back pain, says Marty Matney, LAT, ATC, an athletic trainer in Seattle and chair of the National Athletic Trainer’s Association Council on Practice Advancement. Matney adds that many other smaller muscles that act on the hip can become tight from inactivity too. The body mechanics are complex, but when your hip flexors are tight, it affects pelvic and spinal alignment, and the lower back may take on more than it’s able to, and boom, back pain. If hip tightness gets left unchecked and worsens, you can experience changes in the movement and function of your hip joint as you walk, which can lead to painful hip osteoarthritis. (In the worst case, you may need surgery.) So how do you know if your hips are tight? There are some telltale signs, Matney says: having trouble going from sitting to standing, followed by a few difficult steps; walking in a slightly bent position or having trouble going up or down stairs; and feeling sore in the front of your hip or low back. Knee pain might even result, largely because that tightness causes changes in your gait. The solution is simple: Break that cycle of inactivity and move, which will help increase hip flexibility and mobility. The benefits? “With more hip flexibility, you’ll have easier transitions from sitting to standing, walking will be easier, and you’ll have less pain in your hips and low back,” Matney says.

The Best Daily Hip Stretches

To make those hips and surrounding muscles a little happier, do the following five-stretch routine, created by Matney. Hold each hip stretch for 20 to 30 seconds and repeat on each two or three times (don’t forget to breathe deeply), completing the whole sequence two or three times a day.
