Full Boat PoseParipurna Navasana(par-ee-POOR-nah nah-VAHS-anna)paripurna = full, entire, completenava = boatStep by StepSit on the floor with your legs straight in front of you. Press your hands on the floor a little behind your hips, fingers pointing toward the feet, and strengthen the arms. Lift through the top of the sternum and lean back slightly. As you do this make sure your back doesn't round; continue to lengthen the front of your torso between the pubis and top sternum. Sit on the "tripod" of your two sitting bones and tailbone.Exhale and bend your knees, then lift your feet off the floor, so that the thighs are angled about 45-50 degrees relative to the floor. Lengthen your tailbone into the floor and lift your pubis toward your navel. If possible, slowly straighten your knees, raising the tips of your toes slightly above the level of your eyes. If this isn't possible remain with your knees bent, perhaps lifting the shins parallel to the floor.Stretch your arms alongside the legs, parallel to each other and the floor. Spread the shoulder blades across your back and reach strongly out through the fingers. If this isn't possible, keep the hands on the floor beside your hips or hold on to the backs of your thighs.While the lower belly should be firm, it shouldn't get hard and thick. Try to keep the lower belly relatively flat. Press the heads of the thigh bones toward the floor to help anchor the pose and lift the top sternum. Breathe easily. Tip the chin slightly toward the sternum so the base of the skull lifts lightly away from the back of the neck.At first stay in the pose for 10-20 seconds. Gradually increase the time of your stay to 1 minute. Release the legs with an exhalation and sit upright on an inhalation.
There are lots of people at the wall who do yoga. For 99.9% of them, this is true:
If you are doing yoga at the expense of climbing or training training then it might hinder your climbing performance but otherwise its a beneficial active rest option especially for those with cores of jelly, the chronically inflexible, the posturally contorted and the muscularly imbalanced - and most of us fall into at least one of those categories. Accepted there are alternatives to yoga to deal with those issues.
So beacuse you have seen some people go to the wall and do a bit of yoga stretches and climb badly, therefore Yoga makes you climb like shit.Great leap of logic sherlock.
