Decline Dumbbell Press

Same decline bench, same lower-chest target, but each arm now moves independently, so neither shoulder can lean on the other to finish a rep. Lower the dumbbells until you feel a full stretch across your lower chest, further than a bar would safely allow, then press them back up and slightly in so they finish nearly touching over your chest. Because nothing fixes your hand path, small side-to-side wobble is normal -- control it with your grip and shoulder rather than fighting it with your wrists. Have a spotter hand you the dumbbells at the start; getting into position is the trickiest part.
