The correct squat can exercise the inner thigh muscles that are not usually used, while the foam shaft relaxes the outer thigh muscles, which will be a little stiff if used more often. The muscles of the left and right thighs are balanced, and it is not easy to wear the kneecaps when running. Squat exercise is mainly to exercise the muscle strength of hips and legs, while running has a greater impact on joints, and relatively speaking, the wrong running posture has certain damage to knees. Under normal circumstances, we all know that everything should be done step by step, even during exercise. Only by slowly increasing the weight according to your own ability can you protect yourself when you squat. If you just go to the gym, you will ask for trouble. To sum up, as long as you know the correct way to exercise and gradually increase the amount of training according to your own strength, your risk of injury in sports will be greatly reduced.
When running, the sole of your foot touches the ground, which easily impacts your knees. When squatting, no impact is just a simple knee flexion. It is certain that running hurts the knee, but it is not necessary to squat to exercise the knee. After repeated attempts, I have come to the conclusion that if I want to exercise my knees, I can even repair my previous sports injuries. Not only running, but any exercise will put some pressure on your knees. Squat does train muscle strength around the knee and joint stability, but it is also trained on the basis of correct operation.
