Crunch Single Leg Lift

Description

How to Do Crunch Single Leg Lift

1. 1
   Setup

   Lie supine on the floor with your knees bent, feet flat on the ground, and hands lightly behind your head or crossed over your chest.

2. 2
   Setup

   Engage your core by gently pressing your lower back into the floor, ensuring there is no arch.

3. 3

   As you exhale, simultaneously lift your head and shoulders off the floor into a crunch, while lifting one knee towards your chest until your thigh is perpendicular to the floor.

4. 4

   Pause briefly at the top of the movement, feeling the contraction in your rectus abdominis and iliopsoas.

5. 5

   Inhale as you slowly lower your head, shoulders, and leg back to the starting position with control, maintaining core engagement.

6. 6

   Alternate legs with each repetition, or complete all desired repetitions on one side before switching to the other leg.

Tips

• Maintain a neutral neck position throughout the crunch by looking towards the ceiling, rather than tucking your chin aggressively into your chest.
• Focus on initiating the movement from your core, envisioning pulling your ribs towards your hips instead of relying on momentum or pulling with your arms.
• Control the lowering phase of the movement by resisting gravity, which maximizes muscle engagement and prevents momentum from taking over.
• Keep the non-lifting foot firmly planted on the floor to provide a stable base and help isolate the work to the abdominal muscles and the lifting hip flexor.

Common Mistakes

• ×Pulling on your neck during the crunch can cause strain; instead, use your abdominal muscles to lift your torso, keeping your hands merely supporting your head.
• ×Arching your lower back as you lift your leg indicates disengagement of the core; ensure your lower back remains pressed into the floor throughout the entire movement.
• ×Rushing through the exercise reduces muscle activation; perform each repetition slowly and with control, emphasizing the squeeze at the top and the controlled descent.
