To perform a Barbell bench press, follow these steps:

1. Start by lying flat on a bench with your feet firmly planted on the floor. Your eyes should be directly under the bar.
2. Grab the bar with an overhand grip, slightly wider than shoulder-width apart. Your palms should be facing away from you.
3. Unrack the bar by straightening your arms. Make sure your elbows are locked and your shoulders are pulled back.
4. Lower the bar slowly towards your chest, keeping your elbows at a 45-degree angle to your body.
5. Pause for a brief moment when the bar touches your chest.
6. Push the bar back up to the starting position by extending your arms, while keeping your back, glutes, and feet firmly planted on the bench and floor.
7. Repeat the movement for the desired number of repetitions.

Remember these tips to ensure proper form:

• Keep your back flat against the bench throughout the exercise.
• Engage your core and squeeze your glutes for stability.
• Breathe in as you lower the bar, and exhale as you push it back up.
• Start with a weight that allows you to maintain proper form, and gradually increase the weight as you get stronger.
