From Seated Straddle, bend your left knee and place it on top of your bent right leg so your knees, shins, and ankles are stacked. Keeping the shins parallel, flex the feet to feel a stretch in the calves.
Press your fingertips into the floor behind your pelvis. To make this pose more intense, place your hands in front of your shins and walk them out as far as you can, folding your chest over your legs.
