Abstract
An exercise machine is provided for developing the chest muscles while maintaining correct biomechanical posture and joint movement for the user, thereby maximizing efficiency and safety. The exercise machine includes a track on which two platforms independently slide. The platforms are each interconnected to a weight stack unit or other vertical resistance unit that provide resistance to the inward movement of the platforms. Each platform may also be connected to a tension element or resistance band that is configured to provide gradual and progressively increased resistance as the platforms are moved inwardly towards the center or center stop of the track.
Claims20
An exercise machine, comprising:
- a cross-member having a center point, a first distal end, and a second distal end opposite the first distal end, the cross-member having coupled thereto a first platform on the first distal end side of the center point and a second platform on the second distal end side of the center point, the first and second platform each being configured to slide along the cross-member between an inner position that is towards the center point and an outer position that is towards the corresponding distal end;
- a first vertical resistance unit coupled to the first distal end of the cross-member, the first vertical resistance unit being operably connected to the first platform via a system of pulleys and one or more cables, wherein the first vertical resistance unit provides resistance as the first platform is slid from the outer position to the inner position;
- and
- a second vertical resistance unit coupled to the second distal end of the cross-member, the second vertical resistance unit being operably connected to the second platform via a system of pulleys and one or more cables, wherein the second vertical resistance unit provides resistance as the second platform is slid from the outer position to the inner position.

An exercise machine comprising:
- a cross-member having a center point, a first distal end, and a second distal end;
- a first weight stack unit coupled to the first distal end, the first weight stack unit including a first plurality of weight stack plates;
- a second weight stack unit coupled to the second distal end, the second weight stack unit including a second plurality of weight stack plates;
- a first platform coupled to the cross-member on the first distal end side of the center point, the first platform being configured to slide along the cross-member, the first platform being coupled to the first weight stack unit such that movement of the first platform towards the center point of the cross-member causes at least one of a first plurality of weight stack plates to be lifted to provide resistance to the movement;
- and
- a second platform coupled to the cross-member on the second distal end side of the center point, the second platform being configured to slide along the cross-member, the second platform being coupled to the second weight stack unit such that movement of the second platform towards the center point of the cross-member causes at least one of a second plurality of weight stack plates to be lifted to provide resistance to the movement.

An exercise machine comprising:
- a cross-member having a center point, a first distal end, and a second distal end, the cross-member including a channel that extends along a length of the cross-member;
- a first platform being coupled within the channel on the first distal end side of the center point, the first platform being configured to slide within the channel from a first outward position towards the first distal end and a first inward position towards the center point;
- a second platform being coupled within the channel on the second distal end side of the center point, the second platform being configured to slide within the channel from a second outward position towards the second distal end and a second inward position towards the center point;
- a first vertical resistance unit coupled to the first distal end, the first vertical resistance unit comprising a first top pulley coupled to a top portion of the first vertical resistance unit and a first bottom pulley coupled to a bottom portion of the first vertical resistance unit, the first vertical resistance unit containing a first source of resistance, the first vertical resistance unit further comprising a cable having a first end coupled to the source of resistance and a second end coupled to the first platform, the first cable being routed around the first top pulley and the first bottom pulley such that movement of the first platform from the first outward position to the first inward position causes the first source of resistance to be lifted;
- and
- a second vertical resistance unit coupled to the second distal end, the second vertical resistance unit comprising a second top pulley coupled to a top portion of the second vertical resistance unit and a second bottom pulley coupled to a bottom portion of the second vertical resistance unit, the second vertical resistance unit containing a second source of resistance, the second vertical resistance unit further comprising a second cable having a first end coupled to the source of resistance and a second end coupled to the second platform, the cable being routed around the second top pulley and the second bottom pulley such that movement of the second platform from the second outward position to the second inward position causes the second source of resistance to be lifted.
