Abstract
A rowing exercise machine provides a declining, substantially linear path of motion while offering a consistent force angle at the grip. This allows for a fairly consistent torque application at the shoulder joint, throughout the range of motion of the exercise. The exercise machine includes an input assembly which enables a user to maintain biomechanical alignment of the user's wrist and forearm during performance of the exercise, while maintaining a consistent torque applied to the shoulder joint, in the stability of an exercise machine. The input assembly defines a declining, substantially linear path, where the user's forearms remain substantially parallel to the ground as the input assembly is drawn back.
Claims25
A row exercise machine comprising an input assembly including a first handle portion adapted to be moved from a first position to a second position by a pulling force exerted by a user on the first handle portion in a rowing motion, the input assembly defining a substantially linear path for the first handle portion from the first position to the second position.
A row exercise machine comprising:
- a frame;
- an input assembly pivotably mounted to the frame forward and above of a user, the input assembly including a first handle portion and a second handle portion and defining a substantially linear path for the first handle portion and the second handle portion from a first position to a second position by a pulling force exerted by a user on the first handle portion in a rowing motion;
- and a resistance mechanism operably connected to the input assembly.
A row exercise machine comprising:
- a frame;
- user support structure mounted to the frame including a seat and a chest pad;
- an input assembly pivotably mounted to the frame forward and above of the seat, the input assembly including a pair of four-bar linkage mechanisms each having a primary lever arm pivotable about a primary axis, a secondary lever arm pivotable about a secondary axis, a pair of handle portions operably operatively associated with one each of the primary and secondary lever arms and defining a substantially linear path when moved from a first position to a second position, wherein the pair of handle portions travel to a nadir of the substantially linear path as the pair of handle portions are moved from the first position to the second position and the pair of handle portions travel to an apex of the substantially linear path as the pair of handle portions are moved from the second position to the first position;
- and a resistance mechanism operably connected to the input assembly.
