A weight training machine for allowing at least two of a user's muscle groups to push or pull simultaneously in a synchronized and unified fashion, having at least one common counter or weight resistance mechanism; a first actuating means operatively connected to the at least one common counter or weight resistance mechanism for allowing actuation of the at least one common counter or weight resistance mechanism by a first of the user's muscle groups, and a second actuating means operatively connected to the at least one common counter or weight resistance mechanism for allowing actuation of the at least one common counter or weight resistance mechanism by a second of the user's muscle groups, wherein actuation of both the first actuating means and the second actuation means simultaneously acts upon and or resists against the at least one common counter or weight resistance mechanism. One embodiment is an exercise machine and a drive or actuating mechanism with a lever and fulcrum configuration. The fulcrum has an attached handle, arm, lever or platform means, bearings for operatively cooperating with an axle and/or the lever, and attachment means for additional actuating member or members being operatively connected to the axle. The lever has a means for contact with the user and a weight means for providing a counterweight to the weight of the user, as well as attachment means for operatively connecting with the fulcrum and/or axle. The actuating member or members are attached to the fulcrum, preferably pivotally, and comprise linkages to the axle and/or lever so as to be able to transfer force from the user to the lever. Other embodiments include weight training machines having a moment arm weight, weight stack, or weight plate weight resistance mechanism for creating a weight resistance or weight load. |
