    The high-performance leg extension machine for effective quadriceps training

    Everyone trains their upper body in the gym. The lower body and legs are unfortunately neglected by many strength trainers. But leg training is something everyone can benefit from – improving symmetry and providing maximum body confidence. The anterior thigh muscle or quadriceps is the knee joint’s only extensor muscle, meaning it’s important for many everyday movements. The straight part also creates a flexion or bending of the hip joint and supports it.

    A leg extension machine, sometimes also called a leg extender, is a popular piece of gym equipment for isolated quadriceps training. Stretching out your legs on this machine provides effective exercise and is also beginner-friendly. The eGym leg extension machine is a powerful tool that will make your leg training easier and more efficient than ever before.

    Primary muscles

    Leg extension machine: Important muscles for a powerful knee joint

    The leg extension machine is used to train your anterior thigh muscles, meaning the four-headed muscle in your upper thigh (musculus quadriceps femoris). The quadriceps is the muscle with the densest muscle mass in the body and consists of four parts or heads. These muscles are known as the rectus femoris, the vastus medialis, the vastus intermedius, and the vastus lateralis. The main function of your anterior thigh muscles (quads) is knee extension, to support activities such as running and jumping.

    Digital fitness technology for stronger quadriceps

    The digital technology integrated into the eGym leg extension machine optimizes your leg training, enabling you to achieve faster results. Various features such as digital resistance control provide more effective muscle stimuli. You’ll start enjoying a more sustained increase in strength and build muscle for strong thighs – in less time.

    Our fully electronic range of strength training equipment also includes a leg press. This means you can train your quads on the leg extension machine until they’re fatigued before moving on to the leg press for maximum training benefits. Our digital training concept provides everything you need to push your limits, taking your thigh workout to the next level.

    The leg extension machine software includes special, automatically controlled and science-based training methods to suit all training goals.

    How effective is training with a leg extension machine?

    Leg extension training is a particularly good idea if you want to train your thighs. Machine-supported leg extension training is a classic isolation exercise for the quadriceps. As you perform the exercise in a sitting position, it’s also a great training method for people who have difficulties with advanced exercises.

    Whether leg extension training is recommendable is often discussed and debated at length, since there is a risk of injury to the knee joint. However, there’s a theoretical risk of injuring the knee with every exercise involving the quadriceps.

    Training on an eGym leg extension machine allows you to carefully activate and strengthen the anterior thigh muscles while putting comparatively low strain on the tibiofemoral joint. This makes our training machine very useful for gradually and gently increasing pressure on the knee, for example, after surgery on the cruciate ligament or following a hip replacement. A well-trained anterior thigh muscle helps prevent osteoarthrosis, strengthen the menisci, and avoid knee injuries.

    The maximum training weight of our leg extension machine is 175 kg. However, you should only train with the weight that allows you to perform the full exercise properly, to avoid putting excess pressure on your knee joints.

    Just like all eGym machines, the eGym leg extension machine has been ergonomically and technically designed to ensure you can work out both healthily and safely. Software-controlled starting and finishing positions make it easy to get on and off the machine. The optimal force distribution of eGym fitness equipment ensures training is gentle on joints, reducing risky shock loads.

    Proper exercise technique when using the leg extension machine

    Even if leg extensions seem like a relatively uncomplicated exercise, it is extremely important to do these exercises correctly to avoid damaging the knee. The correct settings on the leg extension machine are key: For ergonomic training, the center of the knee joint must be in line with the machine’s axis of rotation.

    eGym strength training machines save your settings for the next time you visit. Your trainer will adjust the sitting position to suit you when they familiarize you with the machine. This will ensure your knee joint is in the correct position for a safe workout. After that, the leg extension machine will automatically adjust itself to the right setting each time you log in with your chip.

    To minimize risk of injury, you should never train with too high a weight on the leg extension machine. If you cannot complete the movement in a controlled manner, i.e. if you have to quickly swing the foot pad upwards and can’t slowly lower it down, then the weight is set too high. You’ll also notice this if your buttocks lift off the seat during the exercise. The eGym leg extension machine features a max-rep test, which you can use to determine your ideal training weight.

    By varying the range of motion on the machine, you have the option to train your muscles more specifically and without straining certain weak joint sections.


    eGym leg extension training – digital controls for optimal training results

    The ability to digitally adjust the settings of the leg extension machine ensure that you can always achieve your best possible training performance.

    The fully electronic leg stretcher features software to enable effective quads training that takes important training principles into account, such as progressive load increase, effective training stimuli, and periodization.
