Three Stretches to Improve Knee Bending and Range of Motion
If your knee does not bend as far as it used to, tight muscles around the joint may be limiting your range of motion. This can make everyday activities like sitting in a car, getting out of bed, or kneeling feel much harder.
These three stretches focus on the muscles around the knee and help you gradually work toward smoother, more comfortable bending.
Why Your Knee May Feel Tight
After an injury or surgery, the muscles surrounding the knee can become stiff.
This may include:
Hamstrings at the back of the thigh
Hip flexors and muscles at the front of the hip
Tissues around the knee joint itself
When these areas tighten up, bending the knee can feel restricted or uncomfortable.
The goal is to loosen the surrounding muscles and gradually improve how the knee moves.
Stretch 1: Standing Hamstring Stretch
The hamstrings run along the back of your thigh and can contribute to stiffness around the knee when they are tight.
How to do it
Place one foot on a sturdy chair.
Keep your hands on a wall, counter, or another stable surface if you need support.
Keep your back flat.
Hinge forward from the hips.
Think about bringing your belly button toward your thigh.
Stop when you feel a stretch through the back of the leg.
Key form cue
Avoid rounding your back. Let the movement come from your hips.
How long
Hold for about 60 seconds, then switch sides.
Stretch 2: Kneeling Hip Flexor Stretch
This stretch targets the muscles along the front of the hip and thigh.
If kneeling on the floor is uncomfortable, use a couch, bed, or thick cushion under your knee.
How to do it
Start in a half-kneeling position.
Keep your torso upright.
Tuck your pelvis slightly.
Squeeze your glutes.
Slowly shift your hips forward.
Stop when you feel a stretch through the front of the hip.
Key form cue
Do not arch your lower back as you move forward.
Keep your pelvis tucked so the stretch stays focused on the front of the hip.
How long
Hold for about 1 minute on each side.
Stretch 3: Towel-Assisted Knee Flexion
This stretch is designed to help you gradually work into more knee bending.
What you need
A large towel
A pillow if you need additional support
How to do it
Roll the towel into a thick cylinder.
Place it behind your knee.
Use a larger roll if your knee has lost more range of motion.
Bend your knee forward until the back of your thigh presses into your calf and the towel.
Slowly move forward and backward through a small range.
Try to gain a little more comfortable motion with each repetition.
Key form cue
Keep the movement small and controlled. Do not force the knee into a painful range.
If the towel feels too small, use a larger roll or a pillow.
How to Use These Stretches
Try:
Hamstring stretch: 60 seconds per side
Hip flexor stretch: 60 seconds per side
Towel-assisted knee bend: gentle repetitions for 1 to 2 minutes
Move slowly and stay within a comfortable range.
What to Pay Attention To
You should feel stretching and gentle pressure, not sharp pain.
Stop or reduce the movement if you feel:
Sharp or sudden pain
Significant swelling
Locking or catching
A strong increase in symptoms afterward
If your limited knee motion followed a recent surgery or injury, follow the range-of-motion guidance from your clinician or physical therapist.
Conclusion
When your knee feels stiff and does not bend fully, working on the muscles around the joint can help improve mobility over time. Start with the hamstrings and hip flexors, then use the towel-assisted knee flexion drill to gently practice bending.
Stay consistent, move gradually, and focus on comfortable range rather than forcing the knee farther than it is ready to go.
