We all do it—we stretch in the morning to get our blood flowing, we stretch our legs after a long drive, and we stretch our shoulders after sitting at our desks for hours. Stretching is an intuitive movement, not only for humans but for animals as well. (Try doing some yoga on your living room floor without your dog or cat coming by to stretch alongside you!) We stretch because it is a simple and effective way to loosen our muscles and invigorate our bodies.
When I do a deep knee bend like a sumo squat I get a popping in the outside of my left knee. It feels like a big tendon or ligament is slipping per something. It isn’t painful peer se but I’m afraid if I do it a lot it will be. Is that a relatively common symptom for a guy with tight flexors, it bands, etc? Should I just push through it or have it checked out?
Any/all of these will indicate that the client or athlete is attempting to compensate for the weak or under-active muscles. The TFL cramp is a classic illustration of synergistic dominance. A muscle cramps when attempting to shorten in a disadvantageous position. With the hip flexed above ninety, the TFL is already shortened and unable to produce the necessary force to hold in a position of poor leverage. The attempt results in cramping, much like a hamstring cramp in bridging when the glutes are under-active. The same effects are often seen when attempting hanging knee ups (an exercise we almost never do, as it teaches compensation), except the cramp or strain is in the rectus femoris.
Work on strengthening all of your core muscles and glutes. These muscles work together to give you balance and stability and to help you move through the activities involved in daily living, as well as exercise and sports. When one set of these muscles is weak or tight, it can cause injury or pain in another, so make sure you pay equal attention to all of them.
How to: Get on your hands and knees, in a tabletop position (a). Slowly widen your knees out as far as they can go and bring your feet in line with your knees. Your shins should be parallel with one another (b). Flex your feet and ease yourself forward onto your forearms. (If the stretch is too intense, try putting your arms on a block or firm pillow.) Hold for eight to 12 breaths (c). If holding the stretch for longer, try slowly moving your hips forward and backward to bring the stretch to different parts of your hips.
