It also keeps the knees well engaged. U become more aware if they dip, since otherwise ur legs will swing you out of the pose! U have to practically hold the pose with the back of your legs and thighs.
The hand position is not as I wish it to be, at the big toes -- but remember I had just 10 seconds to set the camera in auto mode:) Otherwise, the wider the legs and more firmly the leg-hand position, the sweeter this pose feels.
Really one of the easiest halasana variation there is!
How to reach there:
- Doing the wide legged boat called Merudandasana will develop leg strengtht and balance (somewhat required even if u are on your backside!)
- Doing standing splits and preparation for Hanuman, for wider separation of the legs.
