Machine Incline Chest Press and Decline Bench Press.
Both two really good exercises that activate the muscle fibres in different regions of your chest.
Incline Chest Press focuses on activating the Clavicular Head (upper part) of the Pectoralis Major. The greater the incline, the greater shoulder activation as well.
Decline Bench Press focuses not only on the lower head of your Pectoralis Major, but also activates your Anterior Deltoid (Front part of Shoulder) and your Triceps.
Try them in your next Chest /Full Body or Push Day.
