The machine decline bench press targets the lower portion of the pectoral muscles, along with the triceps and shoulders. Using a machine for this exercise helps maintain proper form and reduces the risk of injury by providing stability and support throughout the movement.

1. Adjust the seat height and angle of the decline bench press machine so that your back is firmly supported and your feet are secure.
2. Grip the handles with your palms facing forward and your hands positioned slightly wider than shoulder-width apart.
3. Press the handles forward and upward until your arms are fully extended.
4. Squeeze your chest muscles at the top of the movement.
5. Slowly lower the handles back to the starting position.
6. Repeat for the desired number of repetitions.
