A vertical jump system is described herein. The system includes a first member and a second member each having a member base that sits under a flooring, a flexible cord that extends between the first member and the second member at a desired height, fixtures coupled to the flexible cord along the first member and the second member. The flexible cord remains at the desired height when contacted. The fixtures are slidable along the first member and the second member and adjust the height of the flexible cord. This configuration allows a user to easily adjust the height of the vertical jump for training, athletics, and competition, without the cord or system components dislodging and causing injury to the user.
