Starfish Crunch (beginner)

Cómo hacer el Starfish Crunch (beginner)

1. 1Lie flat on your back on the floor and spread your arms and legs wide into a starfish shape, with your arms angled above your shoulders and your legs angled outward from your hips.
2. 2Let your lower back rest naturally against the floor and keep your head in a neutral position, looking straight up toward the ceiling.
3. 3Brace your core gently by drawing your navel in, then exhale as you begin the crunch.
4. 4Simultaneously lift your right arm and your left leg off the floor, reaching your right hand diagonally toward your left foot.
5. 5Raise your head and upper back off the floor just enough to feel your abs engage — do not pull your neck forward with your arms.
6. 6Hold the contracted position for a brief pause, keeping the opposite arm and leg hovering just above the floor or resting lightly on it.
7. 7Inhale as you slowly lower your right arm and left leg back to the starting starfish position.
8. 8Repeat on the other side by lifting your left arm and right leg, reaching your left hand toward your right foot.
9. 9Continue alternating sides for the desired number of reps.

Consejos de técnica

• Keep the movement slow and controlled — momentum will reduce the work done by the rectus abdominis and obliques.
• Focus on rotating slightly through the torso rather than just reaching with the arm; this keeps the obliques actively involved.
• Press your lower back lightly into the floor throughout the crunch to prevent the iliopsoas from taking over from the abs.
• Keep your neck long and look up at a slight angle — avoid tucking your chin sharply to your chest, which strains the cervical spine.
• If the full reach feels uncomfortable, shorten the range of motion and build up gradually as core strength improves.

Errores comunes

• Using arm swing and momentum to complete the crunch instead of contracting the abs, which reduces core engagement and can strain the shoulder.
• Pulling the neck forward with the reaching arm, which places stress on the cervical spine rather than loading the rectus abdominis.
• Allowing the lower back to arch away from the floor, which shifts tension onto the iliopsoas and lumbar spine instead of the core.
• Lifting the torso too high off the floor in a full sit-up motion, which exceeds the intended beginner range and may introduce hip flexor dominance.
• Holding the breath during the crunch, which increases intra-abdominal pressure unnecessarily — exhale on the way up and inhale on the way down.
