ABSTRACT:
A combination exercise device includes a trampoline which has a peripheral frame and a resiliently mounted spring member secured to the frame with an upper surface upon which the user may jump. Feet are mounted to the frame for elevating the spring member. The exercise device also includes a step which has a horizontal rigid platform upon which the user may repeatedly step on and off in an aerobic exercise. The trampoline is selectively mounted with respect to the step so that the upper surface of the spring member of the trampoline is selectively disposed above the platform at a sufficient distance to permit the trampoline to be used while mounted over the spring member. In other stages of use the trampoline is removed from the step so that the step may be used in an exercise mode. Alternatively, the trampoline may be of a sufficiently small size that the step and trampoline could be permanently mounted together and both types of exercises could then be selectively performed.
