A swing exercising apparatus which can be used for improving a swing movement performed when practicing a sport or for other exercising purposes. The swing exercising apparatus comprises: a handle portion for grasping by the user; an elongated member having a distal end; a movable weight component for moving along the elongated member between a first position and a second position when the user swings the swing exercising apparatus, the movable weight component being closer to the distal end in the second position than in the first position; and a biasing mechanism comprising at least one elastic element for exerting a force biasing the movable weight component towards the first position when the movable weight component is located away from the first position along the elongated member. The biasing mechanism may comprise an attachment portion to attach the at least one elastic element, the attachment portion allowing the user to detach any of the at least one elastic element to adjust the force. The swing exercising apparatus may comprise a return mechanism comprising at least one elastic element for exerting a second force contributing to return the movable weight component towards the first position when the movable weight component compresses the at least one elastic element of the return mechanism.
