"Sitting nerve inflammation called SCIATICA"? It often causes local pain, radiated pain towards knees or even lower. It may often not be any inflammation but tense overloaded soft tissues (muscles, tendons, ligaments) that press on the nerves and fortunately it gives us signals such as pain so we can do something with it. Especially for those who have still not started doing exercises properly, I created a folder on PINREST where I follow and add ISOMETRIC EXERCISES which when performed properly can help solve core difficulties of musculosceletal disalignments. When doing these exercises, it is not necessary to move the body but the compensating tension of the opposite muscle groups works anyway and so is muscular balance of the body created - it means that the pressure is broken down and the body gets back into a functional and painless state. For those who want even deeper origin of the terminology it would be nice to mention that the name isometric exercise was created not a long time ago through (sports) medicine, but those exercises were performed far back by our ....great great great... grandfathers and grandmothers through Yoga Asanas. Are we going to exercise or play further with the modern (isometrics), respectively ancient (asano) terminology? I wish you a lot of freedom and painless movement.
