Benpres-maskine
Lonero benpres-maskinen er en sammensat underkropsøvelse, der fokuserer på quadriceps. Maskinen muliggør tung belastning med ryglæn, hvilket gør den effektiv til at opbygge styrke og muskelmasse i lårene som et supplement til squat med frie vægte.
Sådan gør du
- Sæt dig i benpres-maskinen og placer fødderne i skulderbredde på platformen.
- Frigør sikkerhedshåndtagene og sænk platformen ved at bøje knæene mod brystet.
- Stop, når dine knæ er bøjet cirka 90 grader, eller din lænd begynder at løfte sig fra sædet.
- Pres igennem hælene for at strække knæene og skub platformen tilbage til udgangspositionen.
- Gentag for det ønskede antal gentagelser.
Teknik-tips
- Keep your lower back and hips firmly pressed against the seat pad throughout the movement.
- Place your feet flat in the middle of the platform with your toes pointing slightly outward.
- Lower the platform slowly until your knees form roughly a 90-degree angle.
- Push evenly through your whole foot, focusing on your heels, to return to the top.
Vejrtrækning: Inhale slowly as you lower the platform toward you, and exhale steadily through your mouth as you push the weight back up.
Almindelige fejl
- Locking your knees at the top can place unnecessary stress on the joint and takes tension off your muscles.
- Letting your lower back lift off the seat rounds your spine under load, increasing injury risk.
- Bringing the platform down too low causes your heels to lift and your lower back to curl.
- Bouncing the weight off your chest at the bottom uses momentum instead of muscle strength.

Where should I feel this exercise?
You should feel your quadriceps (front of your thighs) and glutes working. If you feel it in your knees, check that your feet are high enough on the platform and your knees are tracking over your toes.
How heavy should I set the machine?
Start with a light weight that allows you to complete your target repetitions with smooth, controlled form before adding more load.
Can I do the leg press if I have back discomfort?
The machine provides back support, but if you feel any strain in your lower back, reduce the range of motion and ensure your hips stay glued to the pad.
