As yoga teachers we really care about the correct alignment in poses, not because a pose should look in a certain way, but because the more you work on a pose correctly the more you get from the pose itself.
Forward folds, and particularly Uttanasana, are often performed with the wrong alignments because many practitioners aim to bring the head to the shins before working on anything else.
The aim of the pose is lengthening and stretching the entire backside of the body. This pose if performed with open mind and ease has a very relaxing effect on mind and body! Enjoy it!
Beginners tips: remember, at the beginning you won’t look exactly as in the right photo, and that’s ok! Be patient with your body and make the adjustments that your body need. Fold your legs if you need to and try to bring your chest towards the thighs before bringing your head to the shins or straightening your legs.
