Difficulty level: Intermediate
Target Muscle: Abdominals
Equipment: Bodyweight
Instructions for proper form
1. Start by lying flat on your back with your legs fully extended and your arms straight out above your head. 2. Engage your core by pulling your belly button in towards your spine. 3. Simultaneously lift your legs and arms, creating a ‘C’ shape with your body as you curl up into a crunch. 4. Ensure that your lower back remains in contact with the floor. 5. Pause for a moment at the peak of the movement, then slowly return to the starting position while maintaining control.
Common mistakes to avoid
1. Arching your back instead of curling your spine. 2. Using momentum to lift your legs or arms. 3. Allowing your neck to strain by not supporting it with your arms. 4. Letting your legs drop too low, causing your lower back to lift off the ground.

Variations
Beginner modifications
Begin by performing a standard crunch instead of lifting both legs and arms simultaneously. This can help build up core strength before progressing to the full cocoon crunch.
Advanced progressions
To advance, add a twist at the top of the motion to engage the obliques more effectively or incorporate a medicine ball for added resistance.
