There is MUA method or manipulation under anesthesia. I was wondering if such a method would help increase flexibility like achieving a front or side split? Did anybody try it?
I think it is VERY dangerous, because you can injure or break your ligaments - and that would ruin everything.
And, from the other side, it is a misrespect to other students, detracting their work, because (if you succeed) reduces your amount of pain and hard work, gaining the same result in a more easy way.
Generally, it strongly contradicts with the spirit of MA, for me.
This is dangerous.
If it would be a reasonable way to gain flexibility, it would be common practice. A lot of people dream doing splits.
The pain is annoying, also for me, but it indicates how far you can go savely. Again and again bit more increases the flexibility. Muscles, ligaments, tendons and joints need time to adjust. Breaking one of these makes you more flexible, but more in a wobbly way.
