Come back onto your hands & knees & bring your left foot forward to come into a low lunge stretching the hips, groin & thighs.
Be sure that the left ankle is directly under the knee & that the trailing leg is straight out behind you. The back foot may be flat or toes may be curled under.
Gently lower the hips downward & forwards while thinking of the spine lengthening out through the top of the head.You can leave the hands on the floor, bring them to the front thigh or even raise them above your head with the palms touching.
Repeat on the other side.
