The lying crossover stretch is a supine rotational mobility drill in which one leg crosses the body toward the floor, opening the lower back, glutes and outer hip. It is a stretch, not a strength exercise: there is no load, so it is counted in hold times and rounds rather than reps and sets. Keeping both shoulders pinned to the floor is what makes the rotation happen at the spine and hip instead of in a roll of the whole body. Lifters use it as a cooldown after squatting or between sets of hip work.
What Muscles Does the Lying Crossover Stretch Work?
- Primary: Erector spinae (lower back), gluteus maximus and medius (glutes)
- Secondary: Tensor fasciae latae, piriformis, quadratus lumborum
- Tertiary: Obliques, thoracic paraspinals, pectoralis major
How Do You Set Up for the Lying Crossover Stretch?
Lie flat on your back on a mat with your legs straight and your arms out to the sides at shoulder height, palms down, so your body makes a T. Press both shoulder blades and the back of your head into the floor. Bend your right knee and lift that foot off the mat, keeping the left leg long and the left heel down. Exhale and let the ribs settle before the leg moves.
How Do You Perform the Lying Crossover Stretch?
- Lift the bent right knee toward your chest with the shoulders still flat on the floor.
- Guide the knee across your body to the left, letting the pelvis rotate as it travels.
- Lower the knee toward the floor until you feel the stretch spread through the right glute and lower back.
- Hold the position for 20 to 30 seconds, breathing out slowly on each exhale as the hip settles.
- Bring the knee back to centre under control and set the foot down.
- Return to the flat T position, then repeat on the other side.
What Are the Key Form Cues?
- Pin the opposite shoulder down: keep the right shoulder blade on the mat so the twist stays in the spine and hip rather than turning into a body roll.
- Let the exhale take you deeper: relax the glute as you breathe out and let the knee sink a little further each time.
- Turn your head away from the crossing leg to spread the rotation up the spine.
- Keep the bottom leg long and the heel in contact with the mat.
- Stop where the stretch is a steady pull, not a pinch in the lower back or hip.
What Are the Most Common Mistakes?
- Forcing the knee to the floor with a hand: pulling past your available range tips the pelvis and pinches the lumbar joints instead of lengthening the glute, so let the leg drop under its own weight.
- Letting the far shoulder peel off the mat: the whole body rotates as one unit and the stretch disappears; hold both shoulders down and accept less range.
- Bouncing the leg in and out of position: a stretch reflex fires and the muscle tightens, so hold still and breathe.
- Holding your breath through the position: the trunk stays braced and the hip cannot relax.
- Straightening the crossing leg: a long lever swings the pelvis over and moves the stretch to the hamstring.
What Are the Best Lying Crossover Stretch Variations?
- Bent-knee crossover with the foot supported: resting the foot on the mat shortens the range for stiff hips.
- Crossover with the top leg straight: a longer lever deepens the rotation for anyone already comfortable.
- Figure-four glute stretch: crossing the ankle over the opposite knee shifts the pull into the deep hip rotators.
- Single-leg thread the needle: the same rotation done one side at a time from a seated position.
- Standing crossover twist: the same pattern upright when floor space is short.
How Do You Progress the Lying Crossover Stretch?
- Add range only by letting the knee travel further with the shoulders down, never by pulling on it.
- Build from one hold per side to two or three per round.
- Add a second round later in the session, or run the stretch on rest days as well.
- Lengthen the hold from 20 seconds to 45, or straighten the crossing leg for the last hold.
How Should You Program the Lying Crossover Stretch?
Use the lying crossover stretch at the end of a lower-body orbacksession, or between sets of hip work, most days of the week. Run 1 to 2 rounds of 2 to 3 holds per side, 20 to 45 seconds each, with no rest beyond switching legs. Follow it with a hip flexor stretch so the front of the hip opens as well.
