An exercise apparatus that a user can utilize when alone and which imitates the motion of a trampoline and can also imitate the motion of jumping rope while providing secure support to the user. A horizontal platform is supported on a base that has pivotally connected crossed arms that permit the platform to smoothly move up and down. The resistance is provided by a pneumatic spring assembly located beneath the platform. Compressed air supplied by a simple tire pump and a relief valve enable the user to increase or reduce the pressure of the system, thus controlling the bounce frequency and degree of resistance. A pressure set-up table assists the user in setting the pressure at the proper level for his or her needs and an ergometer accurately determines energy output. A handlebar assembly attached to the platform provides good support and can be vertically adjusted to accommodate the particular support needs of the user.
