Garland Pose or Malasana Pose

Malasana pose stretches the ankles, groins, and back torso.  If your heels don't reach the floor, rest them on a folded blanket. 

Tip; If squatting is difficult, sit on the front edge of a chair seat, thighs forming a right angle to your torso, heels on the floor slightly ahead of your knees.  Lean your torso forward between the thighs.  (Source; Yoga Journal)
