Locked in and seated, all shoulder, no cheat.
Keep your back against the pad and ribs down so the press stays in your shoulders.
Pressing dumbbells from shoulder height with your back against a pad puts the front and side delts under strict, honest load with no leg drive to lean on. Your triceps join in to finish the lockout overhead, and the palms-forward grip keeps the press tracking straight up in front of you. The back support means the only way the weight goes up is if your shoulders push it there.
This version is pressed with palms facing forward from a rack position at the front of the shoulders, with a supported back. It is essentially a strict seated overhead press, the name points at the front rack starting position rather than a different movement.
You are turning the press into an incline press to recruit your chest. Keep your ribs down, your glutes and upper back pinned to the pad, and pick a weight your shoulders can press without your spine bending backwards to help.
Seated is stricter and lets you focus purely on the delts because your legs and core cannot contribute. Standing builds more full-body stability. If shoulder size is the goal, seated is a great default.
