Jump Box 1
Jump box 1 er en plyometrisk kropsvægtsøvelse, der involverer et eksplosivt hop op på en forhøjet kasse. Den udvikler styrke i underkroppen, koordination og kondition, mens den aktiverer forlår, baller og baglår gennem hop- og landingsmekanikken.
Sådan gør du
- Stå foran en stabil kasse eller en forhøjet platform.
- Bøj i knæene og sving armene for at forberede springet.
- Hop eksplosivt opad og fremad, og land blødt på kassen med begge fødder.
- Stå helt oprejst på kassen, og træd derefter ned én fod ad gangen.
- Gentag for det ønskede antal gentagelser.
Teknik-tips
- Stand close to a sturdy box with feet hip-width apart.
- Swing your arms back and bend your knees to load power.
- Explode upward and forward, driving through your entire foot.
- Land softly with bent knees to absorb impact.
- Step down one foot at a time to protect your joints.
Vejrtrækning: Inhale deeply as you lower into the preparation squat, and exhale forcefully as you explode upward onto the box.
Almindelige fejl
- Landing with stiff legs, which places high stress on the knees and lower back.
- Using an unstable box or platform, which increases the risk of slipping or tipping.
- Jumping down from the box instead of stepping down, which creates unnecessary high-impact stress on the joints.
- Choosing a box height that is too tall, causing poor landing mechanics and reduced control.
Aktiverede muskler
Primære: quadriceps. Sekundære: baller, baglår, kredsløbssystem.

How high should the box be for beginners?
Start with a very low, stable surface—around 6 to 12 inches—to focus purely on soft landing mechanics before increasing height.
Can I do jump box 1 at home?
Yes, provided you use a sturdy, non-slip platform or plyometric box that will not slide or tip over.
Why is it important to step down instead of jumping down?
Jumping down doubles the impact force on your joints, significantly increasing fatigue and the risk of injury over time.
What should I do if my knees hurt?
Stop immediately, lower the box height, or switch to a lower-impact movement like regular step-ups until your joints adapt.
