摘要
An exercise device for targeting the gluteus maximus muscle uses a stand to hold up a bellows pump against a vertical surface while a user repeatedly pushes the pump with a foot. The pump has a one-way inlet valve and a small restrictor opening to allow air to leave the bellows slowly, providing a mechanism for selecting different resistance values. A catch is used to keep the pump in the compressed position during storage.
