Use a belt and block to set up for Dolphin at the wall. Keep your shoulders over your elbows and look between your forearms. Keeping your right leg straight, inhale to extend it up. Extend strongly through your right inner heel and inner leg, moving the inner leg toward the wall behind you. Rotate the outer right leg in to keep the hips level. Do not rotate the leg open: This will shift weight to one hand, causing unevenness in the hips. Hold for a few breaths, finding lines of energy from the shoulders through the sides of the body to the inner leg and heel of the right leg, reaching up. Bring the right leg down and switch sides.
