Cross-body Knee Crunch
Cross-body knee crunch er en kropsvægtsøvelse, der målretter de skrå mavemuskler gennem et diagonalt knæløft fra en planke-position. Bevægelsesmønsteret udfordrer både din core-stabilitet ved rotation og styrken i dine hoftebøjere.
Sådan gør du
- Start i en høj planke-position med hænderne under skuldrene og kroppen strakt.
- Før dit højre knæ diagonalt ind under kroppen mod din venstre albue.
- Før foden tilbage til udgangspositionen.
- Gentag på den anden side ved at føre dit venstre knæ mod din højre albue.
- Fortsæt med at skifte side for det ønskede antal gentagelser.
Teknik-tips
- Keep your wrists stacked directly beneath your shoulders.
- Brace your core as if preparing for a gentle tap to the stomach.
- Drive your knee diagonally across your body toward the opposite elbow.
- Exhale smoothly as you twist and drive the knee.
- Lower your foot back to the starting plank with control.
Vejrtrækning: Exhale as you drive your knee across your body; inhale as you return to the starting plank position.
Almindelige fejl
- Sagging your hips toward the floor, which strains your lower back and reduces core engagement.
- Rushing through the movement using momentum rather than controlled core strength.
- Lifting your hips too high into the air, which shifts the work away from your abs and obliques.

What muscles does the cross-body knee crunch work?
It primarily targets your obliques and deep core stabilizers, while also engaging your shoulders, abs, and hip flexors.
Should I feel this in my lower back?
No. If you feel it in your lower back, your hips are likely sagging. Engage your glutes and brace your core more firmly.
Can I do this exercise on my knees if planks are too hard?
It is best to start with standard regressions like a plank knee to chest or a kneeling variation until your core strength builds up.
