A cable and pulley weightlifting apparatus for preventing injury to a weightlifter that includes a pair of bases, a pair of vertical tubular posts, a pair of upper support brackets, a pair of cables, a pair of counterweights, and safety detent pins. Each vertical tubular post has an upper support bracket attached at the upper end and the lower end is attached to the respective pair of bases. Each cable with a counterweight attached to one end is inserted into the channels of the respective vertical tubular posts. The other cable ends with snap hook connectors attached are inserted into the upper support brackets and connected to a dumbbell cable harness or a barbell. The vertical tubular posts include apertures to receive safety detent pins for the weightbearing bar to be suspended at any desired elevation and providing safety to the user not available with other free weight systems.

1. A cable and pulley weightlifting apparatus for preventing injury to a weightlifter comprising: a framework including a pair of laterally spaced base sections, a spaced vertical upright comprising a vertical tubular post extending vertically upwardly from each said base section, said vertical tubular post having a plurality of vertically aligned apertures extending therethrough at regular intervals, said vertical tubular post having an attached upper support bracket, an upper transverse member mounted to and extending between the upper ends of said vertical tubular posts, and a lower transverse member mounted to and extending between the laterally spaced said base sections;a first and second said upper support bracket attached to the upper end of each said vertical tubular post;a first and second pulley system, one said pulley system being contained within each said upper support bracket;a first and second counterweight, one said counterweight being slidably inserted within each said vertical tubular post;a first and second dumbbell cable harness;a first and second dumbbell bar;a first and second cable, said first cable having a first end connected to said first counter weight and said first counter weight being inserted into the open end of said first vertical tubular post and having a second end inserted into said first upper support bracket and then connected to the upper end of said first dumbbell cable harness and the lower ends of said first dumbbell cable harness connected to said first dumbbell bar, said second cable having a first end connected to said second counter weight and said second counter weight being inserted into the open end of said second vertical tubular post and having a second end inserted into said second upper support bracket and then connected to upper end of said second dumbbell cable harness and the lower ends of said second dumbbell cable harness connected to said second dumbbell bar;a pair of safety detent pins, one said safety detent pin being removably insertable into said vertically aligned apertures of each said vertical tubular post, said safety detent pin extending through said vertical tubular posts and defining the upper limit of travel of said counter weight within said vertical tubular posts;whereby said safety detent pins are inserted into said vertically aligned aperture of said vertical tubular posts at a predetermined height selected to perform an exercise such that said safety detent pins will limit the upward travel of said counter weight to prevent the downward travel of said first and said second dumbbell bars below the height selected for the start of an exercise. 2. The weightlifting apparatus as recited in claim 1 wherein the second end of each said cable is connected to the upper end of each said dumbbell cable harness and the lower ends of each said dumbbell cable harness is connected to each said dumbbell bar such that said dumbbell bars are suspended in a balanced horizontal position. 3. The weightlifting apparatus as recited in claim 1 wherein the second end of each said cable is removably connected to the upper end of each said dumbbell cable harness. 4. The weightlifting apparatus as recited in claim 1 wherein the lower ends of each said dumbbell cable harness are removably connected to each said dumbbell bar. 5. The weightlifting apparatus as recited in claim 1 wherein each said dumbbell bar includes ends to receive replaceable weight plates thereon. 6. A cable and pulley weightlifting apparatus for preventing injury to a weightlifter comprising: a framework including a pair of laterally spaced base sections, a spaced vertical upright comprising a vertical tubular post extending vertically upwardly from each said base section, said vertical tubular post having a plurality of vertically aligned apertures extending therethrough at regular intervals, said vertical tubular post having an attached upper support bracket, an upper transverse member mounted to and extending between the upper ends of said vertical tubular posts, and a lower transverse member mounted to and extending between the laterally spaced said base sections;a first and second said upper support bracket attached to the upper end of each said vertical tubular post;a first and second pulley system, one said pulley system being contained within each said upper support bracket;a first and second counterweight, one said counterweight being slidably inserted within each said vertical tubular post;a barbell bar;a first and second cable, said first cable having a first end connected to said first counter weight and said first counter weight being inserted into the open end of said first vertical tubular post and having a second end inserted into said first upper support bracket and then connected to said barbell bar, said second cable having a first end connected to said second counter weight and said second counter weight being inserted into the open end of said second vertical tubular post and having a second end inserted into said second upper support bracket and then connected to said barbell bar;a pair of safety detent pins, one said safety detent pin being removably insertable into said vertically aligned apertures of each said vertical tubular post, said safety detent pin extending through said vertical tubular posts and defining the upper limit of travel of said counter weight within said vertical tubular posts;whereby said safety detent pins are inserted into said vertically aligned aperture of said vertical tubular posts at a predetermined height selected to perform an exercise such that said safety detent pins will limit the upward travel of said counter weight to prevent the downward travel of said barbell bar below the height selected for the start of an exercise. 7. The weightlifting apparatus as recited in claim 6 wherein the second end of each said cable is connected to said barbell bar such that said barbell bar is suspended in a balanced horizontal position. 8. The weightlifting apparatus as recited in claim 6 wherein the second end of each said cable is removably connected to said barbell bar. 9. The weightlifting apparatus as recited in claim 6 wherein said barbell bar includes ends to receive replaceable weight plates thereon.
