There is no doubt that leg muscles are human muscles, so leg training should attract our attention. This is why more and more people are exercising their legs. For leg training, the equipment and actions in the gym are various, and the thigh extension trainer is a common leg training equipment. This device requires us to sit on it, push the thighs and calves, adjust the position and weight, lift, simple and practical, and is popular with many beginners.

But is the thigh stretch trainer really suitable for beginners? First of all, the purpose of the thigh extension trainer is to train the quadriceps of our thigh. The exercise method is to exert great pressure on the cartilage between the patella and the femur. This pressure is greater than squatting. In addition, many people like to do heavy leg stretching exercises, which will increase the pressure of joints, and excessive reliance on thigh stretching trainers will lead to unbalanced muscle development. The leg extension trainer only trains quadriceps femoris, but for ordinary people, such as fitness beginners, their quadriceps femoris is usually more developed than their hind leg muscles. Therefore, if you only use the leg extension machine for training, you can exercise two groups of muscles. The development is increasingly unbalanced. The knee joint is mainly stabilized by four groups of ligaments. One of the functions of the anterior cruciate ligament is to limit the forward movement of the lower leg. If the quadriceps femoris is much more developed than the hind leg muscles, the strong quadriceps femoris may over-guide the joint and increase the risk of anterior cruciate ligament injury. Therefore, it is very important to find your own position. Choosing the right movement and exercise weight will make our exercise effect better. For leg training, we can carry out some self-weight multi-joint training first, such as common squats, lunges and other movements.
