An exercise apparatus comprises a frame having two parallel tracks, two platforms mounted on the first track by a sliding bearing, and two platforms mounted on the second track by a sliding bearing. The tracks are spaced apart a sufficient distance to permit the platforms on different tracks to move freely past each other. A transverse interlock allows selective connection of platforms on different tracks for movement together and a longitudinal interlock allows selective connection of platforms on the same track for movement together. The frame includes cross braces connecting the rails at their ends, and the rails, cross braces, and platforms all include connecting points for permitting the user to selectively connect to and between the frame and the platforms a variety of exercise accessories or appliances. The accessories can include elastic resistance bands, cord and pulley assemblies, handles, weights, and appliances for administering physical therapy. |

1. An exercise apparatus comprising:
a base apparatus including:
a frame having at least two tracks, each comprising parallel rails connected at spaced apart locations by cross braces, wherein each of the rails and cross braces includes a plurality of connection points,four platforms mounted for sliding movement on the tracks independently of each other, wherein at least two platforms are mounted on a first track for movement independently of each other and at least two platforms are mounted on a second track for movement independently of each other and the platforms mounted on the first track, wherein each platform includes a plurality of connections points, andan interlocking mechanism for selectively connecting the platforms together, the interlocking mechanism including a transverse interlock for connecting a platform on the first track to a platform on the second track for movement together and a longitudinal interlock for connecting the platforms on the same track for movement together; and an accessory or appliance including at least one of the following:
a cord and pulley assembly comprising a plurality of pulleys removably and selectively connectable to the rails, cross braces and platforms at connection points thereof for enabling a user to propel at least one of the platforms with the cord,a handgrip including a handle bar spanning a first pair of end brackets that mount the handle bar at spaced-apart locations thereon, with the handle bar spaced from a handgrip base that is removably connectable to a platform at connection points thereof,a weight accessory including a weight bar spanning a second pair of end brackets that removably mount the weight bar at spaced-apart locations thereon, with the second pair of end brackets mounted to a weight accessory base that is removably mountable on one of the tracks for sliding movement along the rails thereof, the weight accessory base being removably connectable to at least one of the platforms at a connection point thereof for sliding movement along the rails with the platform, wherein the weight accessory further includes one or more weights selectively mountable on the weight bar, anda therapeutic appliance including (i) a first mounting bracket removably connectable to a cross brace at a connection point thereof, (ii) a second mounting bracket removably connectable to one platform at a connection point thereof, (iii) a therapeutic member connected between the first and second mounting brackets for movement with the second bracket, (iv) and a cord removably connectable to the one platform at a connection point thereof and to another platform at a connection point thereof, wherein the cord enables a user to move a body part with the therapeutic member by moving another platform. |
