Stand in a ready position hjolding a barbell. Keep your hands just outside shoulder width. Bend at your hips and knees. Lean slightly forward while maintaining a natural arch in your lower back. Keep the weight over the ankles. Pull your shoulder blades back and together, and hold them there.
Contract the muscles in your upper shoulders (levator scapulae and upper trapezius). Pull your arms straight up, bringing your shoulders behind your neck. Hold and continue to contract the levator scapulae and upper trapezius, keeping your shoulder blades together. Slowly lower your arms to the starting position and repeat.
