Lonero Medicine Ball Straight Crunch
Lonero medicine ball straight crunch er en vægtet maveøvelse, der udføres med strakte arme over hovedet, mens man holder en medicinbold. Ved at række bolden opad under crunchen øges vægtstangseffekten, hvilket intensiverer belastningen på den lige mavemuskel (rectus abdominis).
Sådan gør du
- Læg dig på ryggen med bøjede knæ og fødderne fladt på gulvet.
- Hold en medicinbold med begge hænder og stræk armene lige op over brystet.
- Løft overkroppen fra gulvet ved at lave en crunch, mens du rækker bolden direkte op mod loftet.
- Hold pause i toppen og spænd i mavemusklerne.
- Sænk langsomt overkroppen tilbage til udgangspositionen og gentag for det ønskede antal gentagelser.
Teknik-tips
- Keep your lower back gently pressed into the floor.
- Extend your arms straight up toward the ceiling.
- Lift your shoulder blades off the mat using your abs.
- Breathe out as you crunch upward.
- Lower your upper body slowly with control.
Vejrtrækning: Exhale as you crunch upward and reach the medicine ball to the ceiling, then inhale as you slowly lower back down.
Almindelige fejl
- Pulling on your neck with your hands instead of lifting with your chest, which causes neck strain.
- Using momentum by swinging the medicine ball up, which reduces muscle engagement.
- Arching your lower back away from the floor, which can put unnecessary stress on your spine.

Where should I feel this exercise?
You should feel your abdominal muscles working to lift your shoulders. You might also feel some mild tension in your hip flexors and shoulders from holding the ball.
What size medicine ball should I use?
Start with a light medicine ball—around 2 to 4 kilograms (4 to 9 pounds)—so you can keep your arms straight and maintain good form without straining your neck.
How often can I do straight crunches?
You can include core exercises like this 2 to 3 times per week, allowing at least a day of rest between sessions for muscle recovery.
What if my neck starts to hurt?
Neck discomfort usually happens when you pull your head forward with your arms. Focus on lifting your chest toward the ceiling rather than leading with your chin.
