The leg extension is particularly suitable for isolated strain on the thigh extensor muscles. Especially in bodybuilding, this exercise is used to specifically pre-fatigue the muscle in order to then optimally load it in the following leg press exercise. However, the leg extension exercise is not suitable for rehabilitation after a cruciate ligament O. P. suitable.
This exercise is particularly suitable for footballers, as the thigh extension is performed in a movement similar to a shot in football. However, many athletes train these muscle groups sufficiently and forget to train the antagonists of this muscle group. The leg curl is particularly suitable for training the ischiocrural muscles.
Trained muscles
- Quadriceps femoris muscle (M. quadriceps femoris)
- Tailor muscleMusculus sartorius
- Medial extensor of the lower legMusculus vastus medial
- Straight thigh muscleMusculus rectus femoris
- Lateral lower leg extensorMusculus vastus lateralis
- Anterior tibialis anterior muscle
Description Leg Extensions
In order to be able to perform the movement optimally, the device must be correctly adjusted. The knee joint must be in line with the swivel joint of the leg extender to ensure axial execution. The sitting position is chosen so that the gluteal muscles are in contact with the backrest. The feet are not pulled up or stretched as first assumed, but are carried along in a natural movement. The training weight and number of repetitions depend on the training goal.
Modifications
In order to make the exercise more effective, in the advanced area you can turn your feet in (supinate) or out (pronate) at the highest point.
