Abstract
Compact, portable, light, easily assembled, dynamic, exercise equipment having a middle bar to which the first of ends of plural flexible springs are hooked and a footholder to which the other ends of such springs are connected; handle bars are separately and interchangeably attachable to the ends of the middle bar. The flexible springs are connected at one end totally within the length of the middle bar. The above mentioned springs form the only connection between the middle bar and the footholder.
Claims10
A dynamic exercise equipment, comprising:
- a. a main middle bar comprising an elongated bar;
- b. handle bars for said main middle bar, each of said handle bars including grip portion which is rotatable relative thereto each of said handle bars being joinable to a respective end of the middle bar;
- c. means for joining said handle bars to said main middle bar at the respective ends of the middle bar in such a manner that said handle bars are movable between an operative position in which said handle bars extend from the opposite ends of said middle bar, thereby forming with said middle bar a unitary exercise bar approximately as long as the width of the shoulders of a user, and a stored position in which said handle bars are located relatively away from their operative position such that the overall length of the combination of said middle bar and said stored handle bars is substantially no longer than the length of the middle bar;
- d. a stirrup-like member in the form of a closed figure defining a single opening which accommodates the hand or foot of the user, said stirrup-like member being substantially smaller in dimension than the length of said exercise bar;
- e. a flexible spring-like tension member means, for resisting the upward movement of the bar said flexible spring-like tension means being connected at one end thereof totally within the length of said middle bar, said tension member means being the only connection between the middle bar and the stirrup-like member, leaving said handle bars free from said tension member means, and the other end of which is directly attached to the approximate center of one side of said stirrup-like member, such that the opening of said stirrup-like member is disposed approximately central of said exercise bar during use;
- f. means for removably securing said tension member means to said middle bar;
- and
- g. means for removably securing said tension member means to said stirrup-like member.
