Half Way Crunch
Halfway crunch er en core-øvelse med egen kropsvægt, hvor man holder crunchet i midterpositionen og udfører små pulserende kontraktioner. Denne teknik holder mavemusklerne under konstant spænding gennem hele sættet, hvilket øger muskeludholdenheden og forbrændingen sammenlignet med almindelige crunches.
Sådan gør du
- Læg dig fladt på ryggen med bøjede knæ og fødderne fladt på gulvet.
- Placer hænderne bag hovedet og løft skulderbladene fra gulvet.
- Hold crunchet i midterpositionen, cirka halvvejs mellem gulvet og fuldt oprejst.
- Udfør små pulserende crunch-bevægelser fra denne midterposition.
- Fortsæt i det ønskede antal gentagelser eller den ønskede varighed.
Teknik-tips
- Keep your lower back pressed firmly into the floor.
- Lift your shoulder blades just high enough to clear the ground.
- Hold the midpoint and pulse in a small, controlled range of motion.
- Keep your neck relaxed and avoid pulling on your head with your hands.
Vejrtrækning: Exhale as you lift and pulse at the midpoint, and inhale gently as you maintain the hold.
Almindelige fejl
- Pulling on the neck with hands, which strains the cervical spine instead of working the abs.
- Using momentum to swing up and down, which reduces continuous tension on the abdominal muscles.
- Lifting the lower back off the floor, which shifts the effort away from the core and toward the lower back.
Aktiverede muskler

Why do I feel this in my neck instead of my abs?
You are likely pulling your head forward with your hands. Rest your head lightly in your fingertips and focus on lifting with your chest.
How often should I do half way crunches?
2 to 3 times per week is plenty for beginners to build core endurance while allowing adequate recovery time.
Should my lower back come off the floor?
No. Keep your lower back pressed down into the ground throughout the entire exercise to protect your spine and properly target your abs.
