There is no doubt that the leg muscles are the muscles of the human body, so the training of the legs should arouse our attention. This is the reason why more and more people are training the legs. For leg exercises, the gym has a variety of equipment and movements, and the thigh extension trainer is a common leg training equipment. This device requires us to sit on it, push the thigh and calf, adjust the position and weight, raise and lower it, it is simple and practical, and it is loved by many beginners.

But is the thigh extension trainer really suitable for beginners? First of all, the thigh extension trainer is aimed at training the quadriceps of our thighs. The exercise method is to put a lot of pressure on the cartilage between the patella and the femur. This This pressure is even greater than squatting. In addition, many people like to perform heavy leg extensions, which will increase the pressure on the joints, and excessive reliance on thigh extension trainers will make muscle development unbalanced. The leg extension trainer only trains the quadriceps, but for ordinary people, such as fitness beginners, their quadriceps are usually more developed than the hind leg muscles. Therefore, if you only train with the leg extension machine, it is possible to make two sets of muscles. The development is becoming more and more uneven. The knee joint is mainly stabilized by four groups of ligaments, and one of the functions of the anterior cruciate ligament is to restrict the forward movement of the calf. If the quadriceps muscles are much more developed than the hind leg muscles, the stronger quadriceps muscles may lead the joints excessively and increase the risk of injury to the anterior cruciate ligament. Therefore, it is very important to find one's own position. Choosing the right exercise action and exercise weight will make our exercise effect better. For leg training, we can first perform some self-weight multi-joint training, such as common squats, lunges and other movements.d
