The couch stretch is a mobility exercise designed to deeply lengthen muscles along the front of the hip and thigh. This stretch aims to counteract the tightness often caused by prolonged sitting, which shortens the hip flexor muscles. The name comes from the fact that it is typically performed with the back leg elevated on a raised surface, like a couch, bench, or wall. It restores optimal hip extension and improves overall posture.
Primary Muscles Targeted
The primary targets of the couch stretch are the deep hip flexors, specifically the iliopsoas group, which includes the psoas major and the iliacus muscles. These muscles attach to the lumbar spine and pelvis, making their tightness a common contributor to lower back discomfort. Another muscle heavily targeted is the rectus femoris, which is one of the four quadriceps muscles and the only one that crosses the hip joint. Because it spans both the hip and the knee, the stretch’s position—with the knee flexed and the hip extended—forces the maximum length change in this muscle. Engaging the glutes of the back leg helps to stabilize the pelvis and intensify the stretch on the hip flexors.
Step-by-Step Execution
To begin the couch stretch, start in a kneeling position facing away from a wall or sturdy elevated surface, such as a bench or couch. Place the knee of the leg you intend to stretch on the ground, using a pad or cushion for comfort, and slide the shin and top of the foot up against the vertical surface. The knee should be positioned as close to the corner where the floor meets the wall as your current mobility allows.
Next, bring the opposite leg forward, placing the foot flat on the ground so the knee is bent at a roughly 90-degree angle, similar to a lunge position. Crucially, ensure your front foot is pointing straight ahead to avoid unnecessary strain on the knee joint. Once stable, establish a neutral spine by engaging your core and gently tucking your tailbone to posteriorly tilt the pelvis.
This pelvic tuck prevents the lower back from arching, which transfers stress to the lumbar spine and reduces tension on the hip flexors. From this upright position, you can intensify the stretch by slowly driving your hips forward and bringing your torso toward a vertical alignment. The goal is to create a straight line from the hip of the kneeling leg through the torso, maintaining the glute and core engagement throughout the hold.
Modifications and Safety Cues
The intensity of the couch stretch is determined largely by the distance between your back knee and the wall or surface. To make the stretch less intense, a beginner can start by moving the back knee several inches away from the wall. Using a yoga block or a stack of mats under the front knee can also help reduce the strain on the back leg if mobility is severely limited.
To progress the stretch, gradually move the back knee closer to the wall, or attempt to bring your torso fully upright so that your shoulders are directly over your hips. A common error is allowing the lower back to over-arch, which causes discomfort in the lumbar spine and reduces the effectiveness of the stretch. Focus on actively engaging the glute of the stretched leg to stabilize the pelvis and prevent this compensation.
It is important to avoid any sharp pain, especially in the knee joint of the back leg, which may indicate that the stretch is too aggressive. If you feel discomfort, immediately reduce the depth of the stretch by leaning forward or moving your knee away from the wall. A typical hold duration for a static stretch is between 30 to 60 seconds on each side to allow the muscle time to lengthen.
