Begin seated with legs extended in front of you. Sit up tall with abs in and shoulders down. Slowly bend knees out to the sides and slide feet in toward your body until the soles of your feet are touching.
Maintaining good posture, lower knees down to the floor (without pushing on them) as far as you can comfortably. Also try pulling your heels in closer to your body. You should feel a stretch in your inner thighs. Hold for 15-30 seconds. Repeat 2 times.
For a deeper stretch, try to lean forward with the torso (not pictured) as if folding over from the hips and bringing your head down towards the floor.
