Running is a beneficial physical activity for health, but it is also frequently associated with some injuries. Most of the injuries of a runner occur in the knee since this is the central axis of the leg that articulates each step we take while running.
The knee is the largest joint in the body and one of the most complex. It must be very stable to support all our weight when we put our foot on the ground, and at the same time, it must be mobile enough so that it can flex at each step.
So, to prevent knee injuries, it is necessary to strengthen the muscles that support this joint. When we run, the forces are absorbed by both the muscles and the knees. It is for this reason that it is recommended to work all the muscle groups of our leg. This will give you more balance, resistance, and protection to your knees.

On the other hand, you should also strengthen your feet and ankles. In the first case, it is necessary to relax the muscles of the feet and improve the mobility of the fingers. This allows you to have a better stride that reduces the impact on your knees when running.
Before running or doing any physical activity, it is necessary to properly warm up our ankles. This is a mobile joint that absorbs a great deal of force with every step we take. However, if you don't warm up properly, all forces are transferred to the knee, which can cause injury and a lot of pain.
Finally, we must mention that, if you have any pain in the knee or any other joint of the body, you should visit a doctor who specializes in traumatology.
