Knee to Chest Stretch

The knee to chest stretch gently bends the lower back and stretches the muscles around it. Many people with a stiff back, especially first thing in the morning, find it brings relief. It is done lying down and needs no equipment.

1. Lie with both knees bent
2. Hold behind one knee and gently draw it towards your chest

How to do it

  1. 1

    Lie on your back on a bed or mat with both knees bent and feet flat.

  2. 2

    Bring one knee up and hold it with both hands, either behind the thigh or just below the knee.

  3. 3

    Gently draw the knee towards your chest until you feel a comfortable stretch in the lower back and buttock.

  4. 4

    Hold for 20 to 30 seconds, breathing slowly. Keep the other foot on the bed.

  5. 5

    Lower the leg slowly and repeat on the other side.

How many

3 holds of 20 to 30 seconds on each side, once or twice a day. Many people find it helpful in the morning.

Common mistakes

Pulling hard or bouncing. The stretch should be gentle and steady.

Lifting the head and shoulders off the bed. Keep them relaxed.

Holding the breath. Slow breathing helps the muscles relax.

Make it easier

Hold behind the thigh rather than over the knee, and do not pull as far.

Make it harder

Bring both knees up together. Do this only if one knee at a time feels comfortable.

Who it helps

Lower back stiffness
Back pain that eases when you sit or bend forward
Spinal stenosis (back and leg pain on walking that eases when you sit)
Morning stiffness

When to stop and check

This stretch is not right for every back. If bending forward makes your pain worse, or pain spreads further down your leg during or after the stretch, stop and have your back assessed. Avoid it in the first weeks after hip replacement unless your physiotherapist allows it.

Not sure you are doing it right? A physiotherapist can watch you on a video call, correct your form and build a full programme around it.

Frequently asked questions

Is knee to chest good for slip disc?
It depends. Some people with a disc problem feel worse when they bend forward, and for them this stretch is not suitable. A physiotherapist can test which movements ease your pain and which aggravate it.
How long should I hold the knee to chest stretch?
About 20 to 30 seconds, repeated 3 times on each side, is a common approach.
