Squat is mainly exerted by stretching hips and knees, that is, gluteus maximus, quadriceps femoris and tibialis anterior, especially quadriceps femoris. In the process of squatting and standing up, the muscle length changes because of the constant load, which is more like isotonic contraction. Of course, increasing load can effectively stimulate muscle strengthening, and the results of different load training are different.
Squatting against the wall is an action aimed at leg strength training, and many people use it to strengthen the stability of the knee joint. It can avoid repeated friction damage of articular cartilage while reducing fat.
Squatting against the wall because of the fulcrum of the wall, quadriceps femoris and tibialis anterior are more stressed. Moreover, the stimulation ratio of medial head and lateral head of quadriceps femoris varies with the flexion angle of knee joint. When the knee flexion angle is small, it will stimulate the inner thigh muscles, and gradually balance with the deepening of squat. When the knee flexion angle is 90, the inner and outer sides are more balanced.
The first difference between squatting against the wall and squatting is static strength training and dynamic strength training. Squat is more about choosing to bear weight, while squatting against the wall is generally self-weight training. And muscle involvement. Squatting against the wall is mainly to exercise the legs, and besides the legs, the muscles of hips, back and trunk are more comprehensive.
However, it is not recommended to squat against the wall for a long time, otherwise it is easy to produce fatigue damage similar to flat support. Enough is enough, appropriately increase the number of groups, rather than a single time is too long. And it has a certain effect on stovepipe, especially on the front side of the thigh. You can obviously feel that the thigh will tighten, so it looks much thinner.
