Seated 8 Leg Crunch

Description

How to Do Seated 8 Leg Crunch

1. 1
   Setup

   Sit on the floor with your knees bent, feet flat on the ground, and your hands placed behind you for support, with fingers pointing forward or slightly out.

2. 2
   Setup

   Lean your torso back slightly, engaging your core, and lift your feet off the floor so your shins are parallel to the ground.

3. 3

   Exhale as you simultaneously pull both knees towards your chest while twisting your torso, aiming to bring your knees towards your right elbow.

4. 4

   Inhale as you slowly extend your legs back to the starting position, maintaining the torso lean and keeping your feet off the floor.

5. 5

   Exhale again as you pull your knees towards your chest, this time twisting your torso to bring your knees towards your left elbow.

6. 6

   Inhale and return to the starting position with control, completing one full repetition (one crunch to each side).

Tips

• Actively pull your belly button towards your spine throughout the movement to ensure your rectus abdominis and obliques are doing the work, not just your hip flexors.
• Avoid using momentum; perform each crunch slowly and deliberately, especially during the eccentric (lowering) phase, to maximize muscle time under tension.
• Exhale forcefully as you crunch your knees towards your chest and twist, which helps to further engage your deep abdominal muscles and stabilize your spine.
• Keep your torso stable and avoid excessive rocking or swaying. Use your hands for light support, but try not to heavily rely on them to maintain balance.

Common Mistakes

• ×Rounding the Lower Back: Avoid excessively rounding your lumbar spine; instead, maintain a slight natural curve by keeping your core braced and leaning back only as far as you can maintain good posture.
• ×Using Momentum: Do not swing your legs or body to complete the crunch; instead, perform the movement with controlled muscle contraction, focusing on the squeeze and release.
• ×Insufficient Twist: Failing to adequately twist the torso reduces oblique engagement; ensure you actively rotate your upper body to bring your knees towards the opposing elbow on each side.
