It’s a common issue, says Prevention advisor Rob Danoff, director of family and emergency medicine residency programs at Aria Health in Philadelphia. "For people who sit a long time at work, the hip flexors and rotators become tight, and the gluteal muscles become weak," he says. "This combination negatively affects our ability to walk, maintain proper posture, and the stability of our spine."
The rectus femoris is one of the four quadriceps muscles -- the quadriceps are the major muscle group of the front of the upper leg. The rectus femoris attaches to the anterior inferior -- the part toward the feet -- portion of the iliac crest and runs to the base of the patella, also known as the knee. The femoral nerve supplies the rectus femoris with nerves. This is the only muscle that crosses the hip joint, which enables it to work as a hip flexor and a knee extender muscle.
Kneel on your mat with your thighs perpendicular to the floor and tops of your feet facing down. Bring your inner knees together. Slide your feet apart so they are slightly wider than your hips and press the tops of your feet evenly into the mat. Slowly sit down between your feet. Use your hands to turn the top of your thighs inward. Then, lean back onto your forearms and slowly lower torso to floor. Hold for at least 30 seconds.
The good news is that there are plenty of good hip stretches out there that you can do to relieve discomfort, decrease tightness, and increase mobility in your hips. Since your hips are involved in so many of the movements you make (both inside and outside of the gym) stretching them is a great way to keep them feeling good and ready to work for you. Add some of the 12 hip stretches Atkins demos below to the end of your workout, or spend 10 minutes each day just doing a few of them, to improve mobility in your hips.
