The Lying Scissors Cross is a bodyweight exercise performed on your back in which your legs alternate crossing over each other in a scissoring pattern. It primarily engages the hip flexors and adductors (inner thighs), while the core stabilizers work continuously to keep your lower back pressed into the floor. The movement is well suited for building hip endurance, improving adductor strength, and reinforcing core control without any equipment.
Cómo hacer el Lying Scissors Cross
- 1Lie flat on your back on a mat with your legs fully extended and your arms at your sides, palms facing down.
- 2Brace your core and press your lower back firmly into the mat — maintain this contact throughout the set.
- 3Lift both legs to roughly 6–12 inches off the floor, keeping them straight and toes pointed.
- 4Open your legs slightly apart, then sweep the right leg over the left so they cross at mid-shin level.
- 5Open your legs apart again, then sweep the left leg over the right to complete one full repetition.
- 6Continue alternating the crossing leg in a controlled, fluid scissoring motion, breathing steadily — exhale on each cross.
- 7Keep the movement deliberate and even; avoid letting momentum drive the legs rather than muscular control.
- 8After completing the target number of repetitions, lower both legs slowly to the mat rather than dropping them.
Consejos de técnica
- Keep your chin slightly tucked and your neck relaxed — avoid craning your head up to watch your feet.
- The lower you hold your legs to the floor, the harder your hip flexors and core have to work; raise them slightly if your lower back begins to arch.
- Use a controlled tempo — about one second per open-and-cross — rather than letting the legs swing freely.
- Actively squeeze your inner thighs together on each cross to maximize adductor engagement.
- If your hip flexors fatigue before your target reps, take a brief pause with legs raised rather than letting the lower back lift off the mat.
Errores comunes
- Letting the lower back arch off the mat: this shifts stress away from the target muscles and onto the lumbar spine, increasing injury risk — re-brace the core and raise the legs slightly if this occurs.
- Using momentum and swinging the legs: fast, uncontrolled swings reduce time under tension and defeat the purpose of the exercise; slow the movement down so muscles — not momentum — are doing the work.
- Bending the knees: flexing the knees shortens the lever arm and reduces the load on the hip flexors and adductors; keep the legs as straight as possible throughout.
- Crossing at the ankles only without opening wide enough: if the legs barely separate between crosses, the adductors get little range of motion; open the legs to at least shoulder-width apart before each cross.
- Holding the breath: breath-holding raises intra-abdominal pressure and accelerates fatigue; establish a rhythm of exhaling on each cross and inhaling on each open.
Preguntas frecuentes
What muscles does the Lying Scissors Cross work?
The primary muscles engaged are the hip flexors (especially the iliopsoas and rectus femoris) and the adductors (inner thighs). The deep core stabilizers — transverse abdominis and obliques — also work continuously to keep the lower back flat on the mat.
How is the Lying Scissors Cross different from a regular scissor kick?
A regular scissor kick moves the legs up and down in alternating vertical strokes, emphasizing the hip flexors. The Lying Scissors Cross moves the legs horizontally so they cross over each other, which adds a significant adductor (inner thigh) component to the hip-flexor demand.
How many reps or how long should I do this exercise?
A common approach is to count each full cross-and-open cycle as one rep and aim for 15–25 reps per set, or to work for 20–40 seconds per set with 2–4 sets total. Adjust based on your current endurance level and whether this is a warm-up or a main exercise.
Can I do this exercise if I have lower back pain?
If you have lower back pain, proceed with caution: raising the legs closer to 45 degrees reduces lumbar stress compared to keeping them near the floor. If you cannot keep your lower back flat on the mat at any leg height, skip this exercise until your core strength improves or consult a healthcare professional.
Where does the Lying Scissors Cross fit in a workout?
It works well as a hip and core warm-up before lower-body strength training, as a finisher at the end of a leg session, or within a bodyweight circuit targeting the hips and core. Because it requires no equipment, it is also a practical option for home workouts or travel.
