Here's a sample upper back routine for a bodybuilder:

1. **Barbell Deadlifts:** Start your routine with deadlifts. This compound exercise engages multiple muscle groups, including the upper back. Perform 3-4 sets of 6-8 reps, focusing on form and maintaining a strong, neutral spine.

2. **Pull-Ups/Chin-Ups:** These are excellent for targeting the upper back muscles, especially the latissimus dorsi. Aim for 3-4 sets of as many reps as you can manage with good form. You can vary your grip (wide, narrow, palms facing in/out) to target different areas of the upper back.

3. **Barbell Rows:** Use an overhand grip and a barbell to perform bent-over rows. Keep your back straight and pull the barbell towards your lower chest while squeezing your shoulder blades together. Do 3-4 sets of 8-10 reps.

4. **Seated Cable Rows:** Use a cable machine with a close-grip attachment. Sit upright, pull the handle towards your lower chest, and squeeze your shoulder blades together at the end of the movement. Aim for 3-4 sets of 10-12 reps.

5. **Dumbbell Shrugs:** Hold a pair of heavy dumbbells by your sides and lift your shoulders straight up towards your ears, focusing on the contraction in your upper traps. Perform 3-4 sets of 12-15 reps.

6. **Face Pulls:** Use a cable machine with a rope attachment. Pull the rope towards your face while keeping your elbows high and squeezing your shoulder blades together at the end of the movement. Do 3-4 sets of 12-15 reps.

7. **Hyperextensions:** These can help strengthen the lower back, glutes, and even engage the upper back muscles. Use a hyperextension bench and perform 3-4 sets of 10-12 reps while focusing on the contraction of the back muscles at the top of the movement.

Remember, it's crucial to maintain proper form throughout these exercises to prevent injury and effectively target the upper back muscles. Additionally, ensure you're progressively overloading your muscles by increasing weight or reps gradually over time for continued growth and strength development.
