An improved exercise machine for performing a dumbbell press includes a frame, a seat connected to the frame and two independently maneuverable levers with rearward ends that are pivotally connected to the frame behind and above the seat. The forward ends of the levers are adapted to hold removable weights and also include forwardly and upwardly angled handles adapted to be grasped and pressed in an upward arcuate direction by a person supported on the seat. The orientation of the sides of the frames and the levers with respect to the seat insures that pivotal movement of the levers occurs along vertical planes that diverge outwardly from the front of the seat, thereby providing a dumbbell press exercise machine that more naturally accommodates the musculoskeletal movements of a person. |

DETAILED DESCRIPTION This invention contemplates a dumbbell press exercise machine having a frame that pivotally supports the rearward ends of two levers, with forward ends that are adapted to be grasped and moved upwardly in arcuate paths via a typical dumbbell press maneuver, either independently or simultaneously, against weighted plates removably supported at the forward ends, with the exercise motions oriented in a manner that accommodates the natural musculoskeletal structure of the human body.
The frame has sides that diverge outwardly from the front of the machine, and the levers are moved through correspondingly diverging planes.
Moreover, the locations of the non-aligned pivot axes, the lengths and starting angles of the forward ends of the levers, and the angles of the handles attached to the forward ends combine to provide a machine that, based upon feedback from a number of individuals involved in the field of strength training, more naturally accommodates the musculoskeletal movements of a human being during a dumbbell press.
By providing two independently operable levers, each designed to match the natural movement of muscles of one side with respect to the entire body, this improved dumbbell press machine is particularly suitable for rehabilitation after an injury.
In accordance with the objects of this invention, a dumbbell press exercise machine preferably includes a frame, a seat connected to the frame, the frame having two vertically upright sides that diverge outwardly from the front of the seat and two levers, each lever pivotally connected at a rearward end to one of the outwardly diverging sides and having a forward end in front of the seat with an angled handle connected thereto and a weight supporting hub for holding weighted plates.
The pivot axes of the levers are both located above and behind the seat and are perpendicular to their respective sides of the frame.
When the handles are grasped and pressed upwardly in a manner referred to as a dumbbell press, the arcuate paths traversed by the handles and the levers are along vertical planes that diverge outwardly from a vertical midplane that bisects the seat
