1. Shoulder Impingement: Overhead pressing movements can cause impingement of the rotator cuff tendons, leading to pain and discomfort in the shoulder joint.

2. Lower Back Strain: Poor form or excessive weight can cause strain on the lower back and may lead to injury.

3. Neck Pain: Holding the weight overhead for extended periods can cause neck pain and stiffness.

4. Uneven Shoulder Development: If you rely too heavily on one type of pressing movement, such as the barbell shoulder press, you may develop uneven shoulder muscles.

To avoid these negatives, here are some tips:

1. Warm-up: Do a thorough warm-up before starting the shoulder press exercise to avoid any injury.

2. Use Proper Form: Use proper form and technique when performing the shoulder press, and start with lighter weights to master the correct form.

3. Focus on Symmetry: Focus on developing both sides of your shoulders equally, and use different variations of shoulder presses to target different areas of the shoulder muscles.

4. Rest and Recovery: Allow for sufficient rest and recovery between workouts to prevent overuse injuries.

5. Seek Professional Help: If you experience pain or discomfort during the shoulder press exercise, seek professional help from a qualified trainer or physical therapist.
