Andrea Metcalf demonstrates the sit, lean and reach.
Step 1—The Sit, Lean and Reach

Start in a seated position with knees slightly bent. Your pooch sits in front or facing you and, holding onto your pet with both hands, lean back and reach. Simply secure your pet, engage your core and lean back and reach. Keep your spine tall and chest open. Exhale as you lean back, inhale as you sit upright. Perform 10 to 20 alternating repetitions.
