Lying (side) Quadriceps Stretch is a beginner bodyweight exercise for the primary: quadriceps secondary: hip flexors.
Lying on your side, you grab your top ankle and pull the heel toward your glute to stretch the quad and hip flexor of that leg while gravity does the rest of the work.
Hold 2 to 3 sets of 30 to 45 seconds per side at the end of a lower-body session or in a separate mobility routine. It is useful for lifters, runners, and desk workers who feel tight through the front of the thighs and hips, and it is gentler on balance than the standing quad stretch.
Use a towel or strap around the ankle if you cannot reach it, and keep the knees together before pulling. Progress by holding longer, tucking the pelvis more, or gently contracting the quad against your hand for five seconds and then relaxing deeper. The most common fault is arching the back instead of stretching the hip; fix it by squeezing the glute of the top leg throughout the hold.
It targets the quadriceps, mainly the rectus femoris, along with the hip flexors when the hip is pushed forward. It is felt along the front of the thigh and hip.
Hold each side for 30 to 45 seconds, repeated two to three times. Longer total time per week matters more than any single hold.
It is easier because you do not need to balance, so you can relax into it. The stretch on the muscle itself is similar.
