Whether you’re a seasoned yogi or a newbie, you know that your quadriceps — the muscles on the front of your thighs — work hard in many poses. They often feel tired and sore after standing with bent legs Virabhadrasana I and II (Warrior 1 and 2), Or duplicates Setu Bandha Sarvangasana (Bridge Pose)or a long contract Navasana (Boat position). If you practice such asanas regularly, your quadriceps will become stronger. But if you exercise these muscles without stretching them, they will become shorter and tighter as well. So it’s important to balance poses that strengthen your quads and those that stretch them.

Anatomy of your quads

The word quadriceps means “four heads,” referring to the four distinct muscles that all join into one tendon. Three of the four originate in the femur or femur: the vastus medialis, on the inner front of the thigh bone; vastus lateralis, on the external front; and the vastus intermedius muscle, between the other two. The fourth, the rectus femoris, lies on top of the vastus medialis muscle and descends to the middle of the thigh. It originates in the front of the pelvis just below the anterior superior iliac spine (often called the anterior hip bone or hip point in yoga classes). All four muscles unite for insertion, via the quadriceps tendon, onto the patella, or patella. The strong patellar ligament then attaches the kneecap to the top of the tibia, or shin bone.

The quadriceps muscles forcefully extend (straighten) the knee. In positions where the quadriceps fully straightens the knee, such as straight-legged standing, forward bend, and seated positions, the action of knee extension is evident. But the quadriceps also work hard in poses where the leg remains bent, such as Warrior 1 and 2. In asanas, or postures, like this, the pull of gravity on the torso tends to bend the knee deeper, and the quadriceps must be strongly engaged so that it doesn’t simply sink to the floor.

In addition to straightening the knee, the rectus femoris acts as a hip flexor, pulling the torso and thigh toward each other. In boat pose, the rectus femoris performs these two actions at the same time. You must work with other hip muscles, such as your hip flexors, to create the V shape of the pose by lifting the weight of your legs and torso against the pull of gravity. At the same time, it works with the other three quadriceps muscles to hold the knee straight.

Long, strong quads

Keeping your quads strong is important for several reasons. First, strong quads stabilize the knee joints, which are inherently unstable and rely on ligaments and muscles to protect them from injury. Second, research has shown that quadriceps weakness is a predictor of osteoarthritis in the knees. Third, weak quads can reduce your ability to live independently in your later years – as the decades pass, the quads become progressively weaker if not worked on regularly, until it eventually becomes difficult to walk up and down stairs and out of a chair.

Unfortunately, many people of all ages in our sedentary society have weakness in their quadriceps. In fact, this can be true even for people who do a fair amount of walking or running. Although these forms of exercise have many benefits, adequately strengthening the quadriceps is not one of them. Other activities, including bike riding, weightlifting, and yoga do a much better job. If you choose yoga as your primary activity to strengthen your quads, be sure to practice poses that target these muscles about three times a week, and use long stabilization exercises and/or multiple repetitions to build endurance and strength.

Besides strengthening the quadriceps, it is important to maintain its flexibility. They will get short and tight unless you give them a good long stretch at the end of any exercise session you have them in. Even if you don’t strengthen your quads, they will become short if they are not passed through their full range of motion; The soft tissues of the body simply conform to the shapes in which we spend the most time. If you rarely straighten your elbow or extend your arm fully above your head, for example, your elbow and shoulder will gradually lose those parts of normal motion. If the quadrants are shortened, the knee and hip will suffer. If you rarely extend your quadriceps, you will lose the ability to fully bend (flex) the knee. (Of course, other factors, including injuries and arthritis, can also prevent knee bending.)

This loss of full flexion is especially noticeable in Virasana (Hero Pose). It can prevent you from being able to sit on your heels, let alone sit between your heels, as full posture requires. Losing full knee flexion also limits your ability to pull your foot up in Vrksasana (Tree Pose), and creates difficulties in seated poses and forward bends in which one or both knees must be deeply bent, e.g. Janu Sirsasana (Head into Knee Pose) and padmasana (Lotus position).

If the rectus femoris muscle is short, it can limit not only knee flexion but also full extension of the hip. Along with shortening of other hip muscles, such as the psoas and iliopsoas, tightness in the rectus femoris muscle causes the pelvis to tilt forward and the lower back to be excessively curved when standing. Tightness in the hip flexors also contributes to lower back pain in back bends, e.g Setu Bandha Sarvangasana (bridge position), Ustrasana(Camel pose), and Urdhva Dhanurasana (Upward-facing bow position). A sedentary lifestyle plays a role in shortening the hip muscles as well. If you spend long hours sitting, a position in which your hip flexors are shortened, your body will adapt to this shape unless you regularly stretch it in the other direction.

Balance of strength and flexibility

Fortunately, it’s easy (although often not easy) to stretch your quadriceps. Because their job is to extend the knee, to extend it you just have to bend the knee. (A word of caution: If you have knee injuries or arthritis, consult your health care provider before working on deepening your knee flex.)

You can gently bend your knees by lying on your back and pulling your knees toward your chest. Wrap your hands around your legs and pull them down toward your thighs. To bend the knees deeper, do Virasana for two to three minutes on most days. If your knees are stiff and your quads are tight, you’ll need to sit on a prop, such as a yoga block. As your quadriceps flexibility improves, gradually lower the height of the brace. To fully extend the rectus femoris, you should include hip extension (the opening across the front of the hip) as well as knee flexion. The classic yoga pose that does this is Supta Virasana (Reclining hero pose).

Unfortunately, many people with tight quads experience knee pain or lower back pain — or both — in this position. This can be due to poor alignment, so you may want to have an experienced teacher check your knee and back position and perhaps recommend props, such as a bolster or folded blankets, to raise your torso higher than your knees. It’s also a good idea to stretch the rectus femoris muscle for each leg individually, because stretching them together can cause a strong forward pull on the pelvis, causing excessive arching and pain in the lower back. You can do this by practice Ardha Supta Virasana (Semi-Reclining Hero Pose); Place one leg in Virasana while bending the other leg at the knee and placing the sole of the foot on the floor.

You can also stretch each rectus femoris separately in a modified version of Bikasana (frog pose). Lie on your stomach and pull your heel toward the outside of your hip using the hand on the same side so you don’t pull your heel toward your tailbone. Make sure to keep your knees a few inches away from each other, and keep the front of your hip on the extended side on the floor.

If the front of your hip comes off the floor, that means your hip starts to flex, your rectus femoris avoids extending, and your lower back ends up bending. To avoid all these unwanted actions, keep your tailbone heavy, press your pubic bone to the floor, and stabilize the front of your hip. Then gently pull the heel towards the outer buttocks. Visualize the quadriceps stretch while holding the stretch for a minute or more.

This pose can also be a test of quad flexibility: If your heels are several inches from your buttocks, you have plenty of practice to regain your full range of motion. But isn’t that one of the reasons we practice yoga! Because it provides us with a simple practice with which we can work daily toward greater ease of movement, health, and freedom.
