Easy yoga postures to enter this pose from are the Child pose (Balasana)
or Hero pose (Virasana).
Take the arms behind you placing the hands on the feet. The top of the
feet can be on the mat or for less strain on your lower back raise the tops
of the feet off the mat and come on to the ball points of the toes.
Pull the navel both up and back to reduce the strain on the discs in the
lower back.
Have the knees hip width apart or slightly wider. Push the pelvis forward
and raise upwards with the navel and chest.
Experiment with the exact hand placement. Different placements will offer
different benefits. This subject is worth further study.
Benefits This posture mildly stretches the quadriceps especially the rectus femorus.
The lower back is stretched and the shoulders get a great stretch.
Variations:
If you come onto the ball points of the toes this yoga posture is easier on
the lower back. However this variation will cause more pressure to fall on
the knees. There is also another option of placing the hands on the mat
and bending the knees more. Both of these options are very nice postures and
closely related to the one shown.
The shoulders can be opened for more space but it is a really nice
stretch when the shoulders are stretched towards the spine.
Yoga Teacher Tips
The Camel pose can be quite hard on the discs in the spine. Even if you do
things like engage abdominals and other muscles to create space around the
lower back. If students are injured offer them the easy option of placing
the hands on the mat and allowing the knees to bend more.
"Always protect those who may be injured.
Offer easy options so that everybody may enjoy a pose without aggravating
and injury."
