Liggende Vertikale Crunches (Benene Strakt Opad)
Liggende vertikale crunches med benene strakt opad er en core-øvelse med egen kropsvægt, hvor crunchen udføres med benene strakt vertikalt. Den løftede benposition øger sværhedsgraden af crunchen ved at fjerne hjælp fra hoftebøjerne og kræve større aktivering af den lige mavemuskel (rectus abdominis).
Sådan gør du
- Lig fladt på ryggen og løft begge ben strakt op mod loftet, så de er vinkelrette på gulvet.
- Placer hænderne bag hovedet eller over kors over brystet.
- Spænd i mavemusklerne og løft skulderbladene fra gulvet, mens du rækker hænderne mod fødderne.
- Hold et kort hvil i toppen, og sænk derefter langsomt overkroppen ned igen.
- Gentag for det ønskede antal gentagelser.
Teknik-tips
- Keep your legs as straight as possible pointing toward the ceiling.
- Exhale as you lift your shoulder blades off the floor.
- Reach your fingertips up toward your toes.
- Keep your lower back gently pressed into the mat throughout the movement.
- Lower your upper body slowly with control.
Vejrtrækning: Exhale as you crunch upward and reach for your feet, then inhale as you lower your upper body back to the floor.
Almindelige fejl
- Pulling on your neck with your hands because it strains the cervical spine and shifts work away from the abs.
- Using momentum to swing upward because it reduces muscle activation and makes the movement less effective.
- Bending the knees too much because it decreases the challenge on the upper abs by engaging hip flexors.
Aktiverede muskler
Primære: mavemuskler. Sekundære: hoftebøjere.

What if I cannot keep my legs completely straight?
It is completely fine to keep a slight bend in your knees if your hamstrings are tight. Focus on keeping your legs as vertical as comfortable.
Why do my neck muscles hurt during this exercise?
Neck strain usually happens when you pull your head up with your hands. Support your head lightly and let your abdominal muscles do the lifting.
How often can I do vertical crunches?
You can include this exercise 2 to 3 times per week, allowing at least a day of rest between core sessions for recovery.
