Complete the DB Chest Press as a Single Arm and then follow it with the explosive 1 Arm chest on the same side.
The first super set is used for Max Power utilizing "post activation potentiation".
First exercise is a heavy single arm chest press followed by an explosive 1 Arm Chest Press. Please sub out a MB for the DB for the second exercise.

This superset is designed to develop your anaerobic endurance power. The lighter % of loads also presents a great opportunity to incorporate some 4Q movements with powerful intent.
Note higher rep scheme and lower % of max weight used for the first lift. The second exercise has some more volume in order to push the anaerobic system. Even as you start to fatigue its really important to stay focused on maximizing the powerful push out of the squat into the shoulder press.
