Dolphin Plank From Downward Facing Dog, inhale and shift your weight forward coming into plank position. Exhale as you lower onto your forearms so that your shoulders are stacked directly above your elbows and your body is parallel with the floor. Dolphin Plank is an intense pose, so if you can't hold for five breaths, lower one or both knees to the floor. Image Source: POPSUGAR Photography / Louisa Larson
