    The high-performance torso rotation machine for effective abdominal training

    No matter whether you’re after a toned stomach or an impressive six-pack – anyone training their abs should be careful not to neglect their lateral abdominal muscles. Although it’s the front abdominal muscles that will give you a washboard stomach, the external oblique muscle is the largest abdominal muscle of all and requires targeted training for an athletic upper body.

    Torso rotation machines, also known as rotary torso machines, come in various forms that allow you to do the exercise while kneeling or sitting. The eGym torso rotation machine is a powerful professional exercise machine designed for gyms and healthcare facilities, enabling an effective abdominal twist exercise in a kneeling position.

    Torso rotation machine: Important muscles for core stabilization

    The rotary torso machine is primarily used to train the side abs (internal and external oblique muscles). The internal and external obliques’ main purpose is to rotate the torso and transfer power from the arms to the legs. You need to use your arm and abdominal muscles when you train on the torso rotation machine, because you hold yourself steady on the handles. This allows you to better train and improve this transfer of force. Doing this protects the spine in particular from injuries, such as herniated disks and problems caused by overloading.

    How effective is training on a torso rotation machine?

    A torso rotation machine is the perfect piece of gym equipment for an effective workout of the side abs. This machine allows directed training of the target muscles. More than that, the guided exercise makes torso rotation exercises simple and safe for everyone – man, woman, newbie, professional. In contrast to equipment-free abdominal muscle exercises, it’s also possible to precisely adjust the training load by adjusting the training weight.

    However, the benefits you’ll get out of training on a torso rotation machine will depend a lot on the machine you are using. Seated twist machines can be found in various forms, although the type of construction, the machine’s features, and settings available will determine the results. When you use a high-quality strength training machine with perfect biomechanics and a full range of adjustment options, just like the eGym rotary torso machine, your abdominal training will be both more effective and better for you.

    The maximum training weight of our torso rotation machine is 100 kg. This fully automatic gym equipment can be used to support competitive athletes, as well as in fitness training and physical rehabilitation.

    It’s a great idea to train the side abs on a torso rotation machine for more than just visual or esthetic reasons. After all, any advanced fitness and strength training should always take health aspects into account. The internal and external obliques do more than simply moving and rotating the torso. Working in concert with the back muscles, they also have the important task of stabilizing the spine.

    Proper exercise technique when using the torso rotation machine

    The torso rotation machine from eGym is designed in such a way that even beginners can perform the exercises correctly. The machine controls the sequence of movements and helps to ensure correct form via its integrated display.

    The most common mistake that people make on this machine is to involve other muscle groups to assist with the motion. Although this makes it easier to use a higher training weight, it greatly reduces the training effect on the abdominal muscles and increases the risk of injury.

    To perform this exercise correctly, first take a kneeling position on the machine and hold onto the vertical bars with a firm grip. You should hold your chest firmly against the chest pad to ensure you generate the force to twist your pelvis using your obliques. You need to apply outward pressure against the knee pad with your knees to perform the exercise in a controlled manner – you can generate further stability by engaging your core. This starting position will allow you to perform the exercise correctly.

    This exercise can lead to back problems if you have significant shortening of your hip muscles. If this is the case, you should reduce the movement amplitude a little and take care to regularly stretch your hips.

    If you’ve been instructed to only use static exercises following a slipped disc, you can move the chest away from the pad and rotate the entire upper body with the hips.
