发明名称 Jumping jack exercise machine
摘要 An exercise machine for low impact exercise of a person. The machine has a base and a support post extending from the rearward end of the base. Two leg members divergently extend generally downward from a first forward facing pivot point for pivoting about a first axis perpendicular to the support post. A planar foot support is on each leg member and extends forward from the support post. Two arm members divergently extend generally upward from a second forward facing pivot for pivoting about a second axis parallel to the first axis. A handle is on each arm member. The arm members are pivotally joined to the leg members and the second axis slides vertically in engagement with the support post.
