For twine, the main secret is that it depends on the nervous system and the psyche – in the first place. And only secondarily – from muscles and tendons. Sitting on the twine is hindered by the same mechanism that blocks movement for weak muscles and creates clamps after injuries.
Lets split the reflex spasm programmed in the muscles. The reason is fear. But this is the right fear. It protects against injury when there is no power and control – includes clamps or convulsive tensions.
The twine is an unusual posture for the body. In real life, this almost never happens, so this position is subconsciously perceived as dangerous for the body. So, you need to familiarize the body with this pose, make it familiar to the nervous system.
It is wrong to stretch muscles by brute force. You can only injure the muscles, and there will be no benefit from this, and in the future, harmful consequences may gradually accumulate. The main thing for the muscles is to get used to the fact that this position is not dangerous. This requires multiple repetitions and a lot of time.
What is definitely not needed is forceful stretching traumatizing the muscles at the moment of their instinctive convulsive contraction. The muscles should not be stretched, but relaxed. Do not strain, but calm and release.
Since the main thing for relaxation is the nervous system and psyche, it makes sense to try to control it. For example, imagine during the exercise what will happen if you fall. By presenting a bad option, you stop being afraid of it. After this fantasy, stretching is immediately easier. At least I tested it myself, and it works – as soon as you imagine how you fall, the muscles immediately release. At the same time, if you scroll through the options for safety net, then it works worse. Probably because the brain is more important about the idea of the threat, and not about the likely solution. This is an interesting psychological trick that confirms that the main thing for stretching is to remove fear – it is he who constrains the muscles.
It is better to train the twine in such a place, and in such a position that the subconscious mind will perceive as not dangerous. This means that it is best to do this on the floor, in a place where there is something nearby to rest on the body, what to grab onto, and what to push off from if you start falling or make an awkward movement. Any insurance that will “calm” the psyche, reduce the risk of injury, will help relax muscles from convulsive contraction due to an unusual posture.
When, during the split, “he does not let him go further” – the reason is precisely the reflex tension of the muscles, and not that the muscles allegedly lack length. The muscles contract as if by themselves, against your will. And it is usually difficult to believe that such a hard programming is possible, it is difficult to believe that they themselves shrink and do not obey commands.
And so it probably seems that the muscles are just “short”, and they just need to be pulled. Then their injury occurs. Some experts say that after such “stretching” microscopic muscle tears are scarred and persist for life. Because of this, the muscles may later even lose elasticity.
There is one interesting observation, which is additional evidence that the reason is in fear and instinctive reactions, and not in muscle tissue or tendons – when a person is very drunk, or under anesthesia, then twine is not a problem for him. Muscles stretch effortlessly. Simply because there is no convulsive constriction from fear of a dangerous posture.
Those. you need to work not on stretching the muscles, but on stopping their convulsive contraction. Although, training the necessary habit, you still have to “stretch” them, as it were. But this must be done carefully, gradually, and without injury.
It is advisable to exclude any danger, in any form – from the likelihood that a bird will fly by or a dog will run by, provoking a sudden movement at an unfortunate moment, to random people who may not notice you and push you. Even when someone walks too close, it can cause feelings of danger and muscle tension instead of relaxation.
By the way, the muscles of the legs also depend on the muscles of the back and lower back. And, sometimes, stretching out, you wait for the back muscles to relax, after which the legs relax. Therefore, during stretching, control and safety is also important for the back muscles.
If you do not practice for a long time, do not repeat the twine, then the muscles will forget this movement, control will be lost and the instinctive feeling of an unusual dangerous pose will return. Then you will have to start over, gradually persistently convincing the body that this position is not dangerous for it.
