Decline Barbell Press Exercise Steps:
Lie down on the decline bench.
Ankle your feet firmly by pushing the chin against the rollers of the bench.
Hold the barbell in an overhand grip slightly wider than your shoulders. Unwrap the barbell and align it with the shoulders with arms fully extended.
Take a deep breath and lower the barbell down to the mid chest in a steady controlled motion. Push the bar up and extend the arms fully.
Keep your shoulder blades pressed against the bench throughout the movement.
Continue doing this till you reach your rep target.
