By strapping the shins, we track the big lower leg bone, the tibia. This bone is often the missing piece from the feet to the hips - by aligning it, we create a more solid foundation for the pelvic girdle and hips. How to do: Start in mountain pose. Cinch a yoga strap around the thickest part of your calves. Ground the inner and outer feet evenly, then push your lower legs into the strap. Count to five, then release. Keep the inner feet grounded and the knees unlocked.
