When it comes to exercise, many people worry about hurting their knees. So which sport hurts the knee the most?
The answer is: Nothing hurts knees more than sitting!
One internationally respected study found that the incidence of arthritis among fitness runners was 3.5%; And for sedentary people, the incidence of arthritis is up to 10.2 percent!
Sitting for long periods of time causes cartilage to lose its nutrients and “starve to death.” Want proper motion so, just can prolong knee life. But the premise is to master the scientific method and avoid unnecessary damage.
Here’s a list of the most common “correct posture” exercises
Injured knee risk: ★★★☆
Up a hill (stairs) your knees bear about three times your own weight.
And down the hill (stairs), in addition to the weight of the knee to bear the impact of the landing, but also increase knee wear.
Therefore, it is not recommended to climb mountains and buildings as a daily exercise.

Some people think tai Chi involves squats such as “horse steps” that put too much pressure on the knees.
