Opposite leg balance, Part 1: Opposite leg balance cultivates pelvic and low back stability. To begin, place a block on your low back so you know where it is in space. Tuck the left toes and extend the left leg behind you. Keep the toes tucked on the ground and press your back heel towards the wall behind you. For even more feedback, your left heel into a wall. As you bring the left leg into extension, engage the glutes, hamstrings and abdominal wall. Press your hands firmly into the mat. Start by holding this for five breaths, working up to holding it until you tire. Repeat on the right side.
