The Lying Crossover Stretch is a supine flexibility exercise that targets the obliques and outer hip by rotating one leg across the midline of the body. It gently decompresses the lumbar spine while lengthening the lateral trunk and hip musculature. Regular practice improves rotational mobility and helps relieve tightness from prolonged sitting.
How to do the Lying Crossover Stretch
- 1Lie flat on your back on a mat with your legs extended and arms stretched out to the sides at shoulder height, palms facing down.
- 2Bend your right knee to approximately 90 degrees, keeping your right foot flat on the floor.
- 3Inhale to prepare, then exhale and slowly lower your right knee across your body toward the floor on the left side.
- 4Keep both shoulders pressed firmly into the mat throughout the movement — do not allow the right shoulder to lift.
- 5Turn your head to the right if comfortable, creating a gentle rotational stretch through the spine and obliques.
- 6Hold the end position for 20–30 seconds, breathing slowly and allowing gravity to deepen the stretch with each exhale.
- 7Inhale and use your core to guide the knee back to the starting position.
- 8Repeat on the opposite side by bending the left knee and rotating it to the right.
Form tips
- Press both shoulders actively into the mat; if one shoulder rises, reduce how far you lower the knee.
- Let gravity do the work — avoid forcing the knee to the floor, and use a folded towel under the knee if needed.
- Breathe steadily throughout; exhaling deeply on each breath helps the muscles relax and the stretch deepen.
- Keep the non-working leg extended and relaxed rather than braced, so tension does not travel into the opposite hip.
- Move slowly into and out of the rotation to protect the lumbar spine and maintain control.
Common mistakes
- Letting the opposite shoulder lift off the mat — this reduces the rotational stretch on the obliques and puts unnecessary strain on the neck.
- Forcing the knee all the way to the floor — pushing past your range of motion can irritate the lumbar joints; lower only as far as your flexibility allows.
- Holding the breath — tensing up and not breathing prevents the muscles from releasing and limits the depth of the stretch.
- Rushing through the stretch — moving too quickly prevents the nervous system from relaxing into the position; hold each side for at least 20 seconds.
- Letting the bent leg straighten as it crosses — the longer lever drags the pelvis over with it, pulling tension into the lower back instead of the obliques; keep the knee bent near 90 degrees.
Frequently asked questions
What muscles does the Lying Crossover Stretch target?
The primary target is the obliques — both internal and external — which lengthen as the trunk rotates away from the crossing leg. The outer hip on the crossing side is also stretched, and the rotation creates a mild decompression through the lumbar spine.
How long should I hold the Lying Crossover Stretch?
Hold each side for 20–30 seconds to allow the muscles and fascia time to relax. For tighter areas, you can extend to 45–60 seconds. Aim for 2–3 repetitions per side.
When is the best time to do the Lying Crossover Stretch?
This stretch is most effective after a workout when muscles are warm, or as part of a morning mobility routine. It is also useful after long periods of sitting, when the lateral trunk and outer hip tend to stiffen up.
Can I do the Lying Crossover Stretch if I have lower back pain?
Many people find gentle spinal rotation relieves lower back tension, but individual responses vary. Keep the movement slow and stay within a pain-free range. If you experience sharp or radiating pain, stop and consult a healthcare professional before continuing.
Is any equipment needed for the Lying Crossover Stretch?
No equipment is required — only your body weight and enough floor space to lie flat. A yoga mat adds comfort, and a folded towel or cushion can support the knee if it does not reach the floor.
