The One leg Kick!
Take position in picture.
Arms stretched backward. Firmly pressed to sides of body. Fists clenched, face down and chin touching mat or floor. Toes pointed.
Well I have that position wrong!
And this one could be better!
Lie on abdomen, head up, raise chest above mat, stretch arms forward to right angle position, rest clenched fists on mat, stretch legs close together.
Inhale slowly and raise legs about 2inches above mat try to snap kick heel of right leg to buttocks.
Exhale while stretching backward with heel of left leg snap kicks to buttocks.
Note my left leg is not tracking straight!
