Quick Answer: Six stretches done in bed before standing can reduce morning back stiffness by restoring blood flow, gently mobilizing the lumbar spine, and releasing muscles that tightened during sleep. Start with knees-to-chest, then spinal twist, pelvic tilt, figure-four stretch, cat-cow, and child's pose variation. Hold each for 20-30 seconds. These are gentle mobilizations, not aggressive stretches. If any movement causes sharp pain rather than mild discomfort, skip it. Morning stiffness that does not improve with stretching or persists beyond an hour may indicate a mattress problem or an underlying condition.

The alarm goes off. You reach to turn it off and your lower back reminds you it exists. Stiff. Sore. Reluctant to cooperate. You know from experience that once you are up and moving for 20 minutes, it will loosen up. But those first minutes of the day set the tone for everything after.
These stretches are done in bed, before you stand up. They take about 5 minutes. They are gentle enough for most people, including those with chronic lower back issues. The goal is not deep stretching or pain-free perfection. The goal is restoring blood flow and mobility to the lower spine before you load it with your body weight.
Before You Start
A few things to know:
- These are mobilization exercises, not deep stretches. Your muscles are cold in the morning. Aggressive stretching on cold muscles can cause injury. Move gently into each position and hold without forcing.
- Mild discomfort and a stretching sensation are normal. Sharp pain is not. If a movement causes sharp, shooting, or radiating pain, stop and consult a physiotherapist.
- These stretches help with mechanical stiffness (the kind that comes from sleeping in a fixed position). They do not treat injuries, disc herniations, or inflammatory conditions. If your back pain is severe, new, or accompanied by numbness, tingling, or weakness in the legs, see a healthcare provider before stretching.
- A supportive mattress reduces the stiffness these stretches address. If you are stretching every morning because your back is always stiff, the mattress may be the root cause. See our morning back pain guide.
The 6 Stretches
1. Knees to Chest
Lie on your back. Slowly bring both knees toward your chest. Hold behind your thighs (not on top of your knees, which puts pressure on the joint). Gently pull until you feel a mild stretch in your lower back. Hold for 20-30 seconds. Release slowly.
This flattens the lumbar curve and gently stretches the erector spinae muscles that run along the lower spine. It also helps decompress the lumbar discs, which absorb fluid overnight and may feel pressurized in the morning.
Variation: If pulling both knees is too intense, do one knee at a time. Keep the other leg extended or bent with the foot flat on the mattress.
2. Spinal Twist
Lie on your back with both knees bent, feet flat on the mattress. Let both knees drop to one side while keeping your shoulders flat. You should feel a gentle rotation through the lower and mid-back. Hold for 20-30 seconds, then slowly bring the knees back to centre and drop them to the other side.
This mobilizes the facet joints in the lumbar spine and stretches the obliques and quadratus lumborum (the deep muscle on either side of the lower spine that commonly tightens during sleep).
Tip: Extend the opposite arm out to the side for a deeper stretch through the torso. Let gravity do the work rather than forcing the knees down.
3. Pelvic Tilt
Lie on your back with knees bent and feet flat on the mattress. Gently flatten your lower back against the mattress by tilting your pelvis upward (imagine pulling your belly button toward your spine). Hold for 5 seconds, then release. Repeat 10 times.
This is an activation exercise more than a stretch. It engages the deep core muscles (transversus abdominis) and the glutes, which stabilize the lower spine. Waking these muscles up before you stand reduces the load on the spinal joints and ligaments when you first bear weight.
4. Figure-Four Stretch (Piriformis)
Lie on your back with both knees bent. Cross your right ankle over your left knee, creating a figure-four shape. Reach through the gap and pull your left thigh toward your chest. You should feel a stretch deep in the right buttock. Hold for 20-30 seconds, then switch sides.
The piriformis muscle runs beneath the gluteus maximus and can tighten during sleep, particularly in side sleepers. A tight piriformis pulls on the sacrum and lower spine, contributing to morning stiffness. This stretch is also helpful for anyone with sciatic-type pain, as the piriformis can compress the sciatic nerve when tight.
5. Cat-Cow (Modified for Bed)
Come to a hands-and-knees position on the mattress. Slowly arch your back downward (cow: belly drops, head lifts). Then slowly round your back upward (cat: belly lifts, head drops). Move between these two positions slowly, spending about 3 seconds in each. Repeat 8-10 times.
This mobilizes every segment of the spine through flexion and extension. The mattress surface provides a softer surface than the floor, which is easier on the wrists and knees. The movement increases blood flow to the spinal discs and lubricates the facet joints.
Note: If your mattress is very soft, this exercise may be difficult because your hands and knees sink in. Perform it near the edge of the bed where the surface is firmer, or do it on the floor if you prefer.
6. Child's Pose Variation
From the hands-and-knees position, sit your hips back toward your heels. Extend your arms forward on the mattress and let your forehead rest on the surface. You should feel a gentle stretch along the entire spine. Hold for 20-30 seconds. Breathe slowly.
This decompresses the lumbar spine and stretches the latissimus dorsi (the large back muscles that can contribute to lower back tension). It is also a calming position that helps transition from lying down to being upright.
Make It a Habit
These stretches work best as a daily routine rather than an occasional fix. Set your alarm 5 minutes earlier and do them before standing. Most people notice a difference within the first week. The stiffness does not disappear entirely (that requires addressing the cause), but it is reduced enough to make mornings significantly more comfortable.
When Stretching Is Not Enough
If you stretch every morning and the back pain persists or worsens, the stretches are managing a symptom rather than addressing the cause. The two most common causes of persistent morning back pain are:
- A mattress that does not support spinal alignment. If the mattress sags or is the wrong firmness, your spine spends 7-8 hours misaligned every night. Five minutes of stretching cannot undo 8 hours of poor positioning. See our morning back pain guide for diagnostic steps.
- An underlying structural issue. Disc degeneration, facet joint arthritis, or muscle imbalances that require professional assessment. A physiotherapist can identify specific issues and prescribe targeted exercises beyond general stretching.
Brantford Physiotherapy Resources
If morning back pain persists despite stretching and mattress changes, consult a physiotherapist. Most Ontario residents can self-refer without a doctor's note. Local clinics in Brantford offer spinal assessments that identify specific muscle weaknesses or joint restrictions. A targeted exercise program combined with a supportive sleep surface is more effective than either approach alone.
Frequently Asked Questions
Can I do these stretches if I have a herniated disc?
Some of these stretches (knees to chest, spinal twist) involve spinal flexion and rotation, which can aggravate certain disc herniations. If you have a diagnosed disc issue, consult your physiotherapist before starting any new exercise routine. The pelvic tilt and cat-cow are generally safer because they involve controlled, small-range movements. Stop any exercise that causes radiating pain down the leg.
How long should I hold each stretch?
20-30 seconds per stretch is sufficient for morning mobilization. Longer holds (60+ seconds) are more appropriate for evening stretching when muscles are warm. In the morning, the goal is gentle mobilization, not deep flexibility work. If 20 seconds feels too intense, start with 10-15 seconds and increase gradually over days.
Should I stretch before bed too?
Evening stretching can help reduce overnight muscle tension. The same stretches work, but you can hold them longer (30-60 seconds) because your muscles are warmer after a day of movement. Evening stretching combined with morning stretching provides the best results for chronic morning stiffness.
Will a better mattress reduce my need for morning stretches?
Yes. A mattress that properly supports spinal alignment reduces the mechanical stress that causes morning stiffness. Many people who switch from a sagging or overly soft mattress to a supportive pocket coil mattress find that morning stiffness decreases significantly or disappears. The stretches remain a good practice but become optional rather than necessary. Visit Mattress Miracle at 441 1/2 West Street, Brantford, or call (519) 770-0001.
Is it safe to stretch in bed or should I use the floor?
Bed is fine for these gentle mobilizations. The softer surface is actually easier on joints (knees, wrists) for exercises like cat-cow and child's pose. For more demanding exercises (planks, bridges), the floor provides better stability. The convenience of bed stretching is the main advantage: you are already there, and the 5-minute commitment is easy to maintain as a habit.
