The Hammer Jump sees Amy smack her Piko Piko Hammer into the floor with enough force in order to launch herself high up into the air. The upward force from the move propels Amy much higher than a regular jump will allow, making it useful for reaching higher ledges.
In Sonic Adventure and its re-releases, the Hammer Jump requires that Amy be running at full tilt. When she is running at maximum speed, as shown by Amy wielding her hammer as she runs, pressing or will perform the move, leaving a shockwave of pink hearts. If she is not in a full run, she will instead use her Hammer Attack and break her momentum.
In Sonic Advance 3, Amy can only perform the Hammer Jump when she is teamed up with Knuckles. It is performed with the same button combination, however unlike its previous appearance in Sonic Advance, the Hammer Jump in this game launches Amy at a slight forward angle instead of directly upwards.
