The Lying Criss-Cross Legs exercise is performed on your back with legs raised, alternately crossing one leg over the other in a continuous scissors pattern. This motion targets the inner thigh adductors — adductor brevis, adductor longus, adductor magnus, and pectineus — along with the gluteus medius, with gracilis and tensor fasciae latae acting as synergists. It is well suited for building hip adductor endurance, improving hip stability, and strengthening the muscles that control leg crossing and lateral hip movement.
Cómo hacer el Lying Criss-Cross Legs
- 1Lie flat on your back on a mat with your legs extended and your arms resting at your sides, palms facing down.
- 2Engage your core by drawing your navel gently toward your spine, pressing your lower back into the mat.
- 3Lift both legs off the floor to a 45- to 90-degree angle, keeping them straight with a soft bend at the knee if needed.
- 4Open your legs slightly apart to create a small V position — this is your starting point.
- 5Cross your right leg over your left leg so the right passes above the left at approximately mid-shin level.
- 6Open your legs back to the starting V position and immediately cross your left leg over your right.
- 7Continue alternating in a controlled, rhythmic scissors motion, fully extending through each cross and opening.
- 8Keep your lower back pressed into the mat throughout — avoid letting it arch away from the floor.
- 9Perform the desired number of repetitions, then lower both legs slowly to the mat to finish.
Consejos de técnica
- Press your palms actively into the floor to help stabilize your pelvis and prevent your hips from rocking side to side.
- Focus on generating the crossing motion from the hips rather than just swinging from the knees — the adductors do the work when the drive comes from the upper leg.
- Keep your toes pointed or flexed consistently throughout the set; changing foot position mid-set reduces neuromuscular control.
- Lower your legs closer to the floor to increase the challenge on your core and hip flexors; raise them higher to reduce the demand if your lower back lifts.
- Move at a deliberate pace rather than using momentum — a slow, controlled cross recruits more adductor and gluteus medius tissue than a fast swing.
Errores comunes
- Allowing the lower back to arch off the mat: this transfers load from the target muscles to the lumbar spine and hip flexors, reducing adductor recruitment and risking low back strain.
- Using momentum instead of muscle control: swinging the legs rapidly reduces time under tension in the adductors and pectineus, diminishing the training effect.
- Making the crossing range too small: shallow crosses that barely pass the midline provide insufficient adductor activation — ensure each leg clearly crosses the opposite leg with each repetition.
- Holding the breath: breath-holding increases intra-abdominal pressure and creates unnecessary tension; exhale on each cross and inhale on each opening.
- Letting the hips tilt or rotate: if one hip lifts off the mat during the cross, the gluteus medius is compensating poorly — reduce speed and focus on keeping both hips level.
Preguntas frecuentes
What muscles do Lying Criss-Cross Legs work?
The primary muscles are the adductor brevis, adductor longus, adductor magnus, pectineus, and gluteus medius — all of which control the inward and crossing movement of the legs. The gracilis and tensor fasciae latae assist as synergists, helping stabilize the hip through the range of motion.
How is the Lying Criss-Cross Legs exercise different from flutter kicks?
Flutter kicks move the legs up and down in alternating vertical strokes, emphasizing the hip flexors. The Lying Criss-Cross Legs moves the legs side to side and across the midline in a horizontal plane, which shifts the emphasis to the inner thigh adductors and gluteus medius instead.
Can I do Lying Criss-Cross Legs if I have lower back pain?
If you can keep your lower back flat on the mat throughout the exercise, the movement is generally low-risk for mild lower back discomfort. Raise your legs higher toward vertical to reduce the lever arm and lumbar load. If your back arches at any point or you experience pain, stop and consult a physiotherapist before continuing.
How many reps and sets of Lying Criss-Cross Legs should I do?
For endurance and tone, perform 3 sets of 20 to 40 total crosses (counting each leg cross as one rep). For strength-focused work, slow the tempo and aim for 3 sets of 12 to 20 reps with deliberate pauses at the crossing point. Rest 30 to 60 seconds between sets.
Do Lying Criss-Cross Legs help with inner thigh tightness?
The exercise strengthens rather than stretches the inner thigh adductors. Strengthening these muscles can improve their resilience and reduce the sensation of weakness-related tightness, but if your goal is flexibility, pair this exercise with static adductor stretches after your workout.
