For the average person, most of them can last for more than 30 seconds. The physical condition of the subjects is no problem from the performance of playing football every week, but it can only last for more than ten seconds when squatting against the wall.
I think the reason is that the muscle exertion mode is unfamiliar and the nerve control ability is poor, which is "inadaptability".
In football, the strength, endurance, explosiveness and agility of both legs have been exercised, showing a more comprehensive physical quality. However, squatting against the wall, lunge and squat are all special lower limb strength training, and the training force mode is quite different from football.
Action training: feet are shoulder width or close together, toes are facing forward, knees and toes are pointing in the same direction. The core is tight and the spine is neutral. The upper body squats against the wall to the vertical ground of the calf, and the knee joint is greater than or equal to 90 degrees.
Practice 5- 10 groups each time, each group can 10 seconds, mainly to be familiar with the action force mode.
Auxiliary training squat: improve the strength endurance of lower limbs, pay attention to hips and knees, knees point to toes, and the spine is neutral. When the number of squats increases, the strength endurance of the lower limbs is enough to extend the time of squatting against the wall.
Then try to choose a time with better physical condition when testing this training time.
Like the average person, even if you don't exercise, you just need to keep it for about 30 seconds, and the shorter one may be about 20 seconds.
Then I personally suggest that you can do this in the next test.
In this case, the test should be more accurate.
If so, if there is no problem with time, it should be this leg muscle measured after your strenuous exercise. It has no strength.
In addition, if you say that you are not too tired and the data is short, then you should strengthen your leg muscles more.
But I don't think this will happen either. You can look at it in detail.
I hope it helps you.
I want to ask, is it harmful to your knees? Or is it protective for the knee?
I can persist for a long time because I am a neat freak. I don't let my skin touch the toilet when I go to the toilet. They are all squatting. So I practiced. Pay attention to me if you feel terrible, or you can praise me privately.
It should be because of insufficient muscle training and inappropriate way of exerting strength.
I am 45 years old. I only spent 2 minutes sitting still some time ago. After a month's training, I can spend four and a half minutes now.
Friction, this is a false proposition with loopholes. Can the same person insist on smooth walls and rough walls at the same time?
I do it for 35 seconds every three times.
How much do you weigh I can stand up for five minutes from one minute.
There is no foundation for exercise at ordinary times. If you persist in doing it, you will naturally make progress.
Haven't you ever practiced squatting? When I was a child, I used to spend 3-5 minutes in a group.
