I’d be more concerned about your interest in being right than I would in backbending. However, I’ll humor the post a bit further along. But let me preface further comment by saying there is NO right or wrong just as there is NO one truth. Now onward…
There is not sufficient room in Yoga for the phrase “extreme”. The very nature of such a phrase implies danger as it means going beyond a reasonable point. Now, there are some yoga practices for which the student is fitted to the pose. This is not a flavor of yoga I enjoy, choose (as a practitioner) or teach (as a sentient being).
In the practice of Purna Yoga, in which I am trained, the poses are fitted to the student. We do not teach poses, we teach students. If you are unable to fold, you are thus not expected to fold so that my ego may be satiated by you “being” in “the” pose.
In Purna Yoga it is always safety first. We over-engineer safety. And so for us (those who teach and train in this discipline) the student is not a) doing extreme anything, including backbends, b) forced or adjusted to a perfect pose they are not ready to move into, and c) placed at risk of injury.
Let’s take your case of a 30 year old and assume it is a male who has a little or no physical fitness activity or background. Should that man walk into a class and be doing Urdhva Dhanurasana 45 minutes later? Probably not. Perhaps, but probably not. And when the answer is “yes” it is only after that student has demonstrated preparatory actions and alignments to remain safe in the pose. There’s that pesky safety thing again. What a crosss we bear.
The stretching, as you say, is a custom fitted suit not a buy off the rack. It must fit that student, their body, their mood, their mobility, at exactly that moment of doing.
As for beginners or raw beginners, of course they can avoid stretching into the tendons. If they could not then Asana would be uniformly dangerous across the board. However it is important to mention that not all “pain behind the knee” is an over stretched tendon. Just as not all men are pigs. Many are but some are not. The student in asana will of course feel things in their physical body and there should be some ache but there should never ever be sharp pain in a joint unless you are actually trying to damage it.
You also mention “spread the legs sitting forward bend” and the reply there is that stiff students have NO BUSINESS doing such a pose. None. The sacrifice a stiff beginner would make to be in such a pose (mostly to follow along either with a group or the dance of their own Ego) is dangerous. In that respect you are right. For the stiff beginner it is enough to find the action and body awareness that go along with lengthening the spine BEFORE forward bending. Honestly, many intermediates can fold but do not mantain the spinal length and therfore they are at risk too. But I am not their teacher so they will not be mumbling my name in five years. I can only teach those that come in my door, virtual or otherwise.
If you want to move toward experiencing such a pose lay on your back and wiggle until your sitting bones contact the baseboard (where the wall meets the floor). Extend the legs up the wall (as in viparita karani), then move your legs apart. This will keep your back passive and allow you to open the groins while mentoring the safety of the sacroiliac joint and lumbar spine.
[QUOTE=klvn168;5555]Dear InnerAthlete,
How about ‘extreme’ back bend for those who start practicing yoga at around 30 years old? Or actually everybody can go for extreme stretching as long as they are prepare and the body allow it to go for it?
As for the knee, i think most of the beginners who suffer from stiff hamstring and lower back can’t avoid stretching the tendon or the feeling pain behind the knee cause they are stiffness on most of the joint and muscle group. Am i right? Sitting forward bend may be can modify by bending the knee, but how about spread leg sitting forward bend? normally the practisioner will feel discomfort the inner side of the knee which is the tendon and ligament located. So is this ok?
Thanks and best regards
