     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     An improved exercise bench of the type having: 
     (a) an elongated bench frame comprising: 
     (1) a head section having two vertical posts (1), each having first and second ends. Small foundations (2) are underneath each said second end. Upper and lower horizontal supports (3), each being adjoined at respective ends by 45 degree supports (4), adjoin said vertical posts (1) generally midway between said first and second ends and at the second ends. Two vertical supports (5) adjoin said horizontal supports (7) are affixed to said first ends of said vertical posts (1). Weight brackets (8) which slide vertically in and out of said vertical posts (1) support barbells and allow for a plurality of exercises. Handles (9) adjoined to a backside of said weight brackets (8) allow said user to perform dip exercises. 
     (2) a foot section having a vertical post (10), first and second ends, and a small foundation (11) underneath said second end. 
     (3) a midsection has a horizontal bar (12) adjoined at said second end of said vertical post (10) at said foot section and midway of the lower horizontal support (3) at said head section. Two generally smaller horizontal parallel bars (13) are adjoined respectively at opposite sides at said first end of said vertical post (10), at said foot section, and generally midway of the upper horizontal support (3) at said head section. 
     (b) a pulley system comprising: 
     (1) a post (14), having first and second ends, in which the said second end slides and rests inside the vertical post (10) at said foot section of said exercise bench. Two parallel plates (15) are adjoined respectively at opposite sides of said first end of post (14). Two pulleys (16) on each respective side of said post (14) are adjoined between the two said parallel plates (15). 
     (2) a cable (17) of variable effective length, having first and second ends, passing through said pulleys (16), each respective end having hookups consisting of cable crimps (18) and adjustable pins (19). The first end of said cable (17) allows for a plurality of separate attachments for persons exercising on said bench. The second end of said cable (17) allows for connection to a weighted carriage. 
     (3) an improved carriage comprising: 
     a. a sleeve (20), having first and second ends, mounted through said post (14); 
     b. two spring angle braces (21) adjoined respectively at opposite sides at said second end of said sleeve (20); 
     c. spring holders (22) adjoined and centered underneath said angle braces (21); 
     d. springs (23) affixed inside said spring holders (22); 
     e. a plate (24) adjoined at said second end of said sleeve (20) at opposite side of said bench frame; 
     f. a slightly upwardly angled weight mounting bar (25) adjoined and centered on said durability plate (24); 
     g. a hoist angle brace (26) adjoined at said first end of said sleeve (20) at the opposite side of said bench frame; 
     h. a hoist bar (27) adjoined and centered on said angle brace (26); 
     i. a weight control sleeve (28) mounted through said hoist bar (27); 
     j. a weight control sleeve link (29) adjoined and centered at the top of said weight control sleeve (28); 
     k. a weight control sleeve nut (30) adjoined and centered at one respective side of said weight control sleeve (28); 
     1. a weight control thumbscrew (31) for fastening the control sleeve nut (30) to the hoist bar (27). 
     Advantages of the improved carriage: 
     1. The weight is mounted on opposite sides of said bench frame onto said angled weight mounting bar (25) thus allowing maximum room for said user on said bench. On prior art carriages, the weight mounting bar is transverse to the bench on the user&#39;s side of bench thus crowding exercise movements. 
     2. On prior art carriages, weights are to be added onto either side or both sides of the weight mounting bar. If equal amounts of free weights are not on both opposite sides, there is a tendency for increased friction on the sides of the sleeve during the carriage&#39;s upward and downward movement over the pulley system post during the user&#39;s performance. On said improved carriage, weight is mounted on said angled weight mounting bar (25) thus always having equal weight on opposite respective sides. As more weight is mounted on said angled weight mounting bar (25), the weight mounting sleeve (28) can be adjusted to minimize friction on other opposite respective sides of said improved carriage during user preformance. 
     3. On said improved carriage, said springs (23) are provided on respective sides to minimize shock when weighted and the carriage returns to the original position after each user performance. 
     (c) an improved seat adjusting assembly comprising: 
     (1) two horizontal sliding sleeves (32), each having first and second ends, mounted through said horizontal parallel bars (13) at said midsection frame; 
     (2) a vertical seat sleeve (33) adjoined between said horizontal sleeves (32) at said first ends; 
     (3) a vertical seat/row sleeve (34) adjoined between said horizontal sliding sleeve (32) at said second ends; 
     (4) two nuts (35) adjoined and centered on opposite outside respective sides of said horizontal sliding sleeves (32); 
     (5) two thumbscrews (36) for fastening the sliding sleeves (32) onto the parallel bars (13) for adjustment purposes; 
     (6) a seat bar (37), having first and second ends, is mounted through said vertical seat sleeve (33) with the second end in a lower position; 
     (7) two seat bar rods (38) are adjoined and centered transverse to said horizontal parallel bars (13) at said first end of said seat bar (37); 
     (8) four seat bar rod sleeves (39) mounted flush on outer sides of said seat bar rods (38); 
     (9) an upper seat plate (40) adjoined to the two said seat bar rod sleeves (39) nearest to said head section of said exercise bench; 
     (10) a lower seat plate (41) adjoined to the two said seat bar rod sleeves (39) nearest to said foot section of said exercise bench; 
     (11) an upper bench seat (42) affixed to said upper seat plate (40); 
     (12) a lower bench seat (43) affixed to said lower seat plate (40); 
     (13) a seat/row bar (44), having first and second ends, is mounted through said vertical seat/row sleeve (34) with the second end in a lower position; 
     (14) an angled seat brace (45) adjoined transverse to said horizontal parallel bars (13), at said first end of said seat/row bar (44). 
     Advantages of the improved seat adjusting sleeve assembly: 
     1. The bench seat assembly can be completely removed by sliding assembly out of said vertical seat sleeve (33). The bench seat assembly can be positioned on a floor for sitting purposes by said user during a plurality of exercises. 
     2. The vertical seat sleeve (33), vertical seat/row sleeve (34), seat/row bar (44), angled seat brace (45), seat bar (37), seat bar rods (38), seat bar rod sleeves (39), upper seat plate (40), lower seat plate (41) and affixed bench seats (42) (43) allow vertical type swivel accessibility for both said bench seats (42) (43). Raising and lowering of said seat bar (37) and said seat/row bar (44), and support from a crossbar (46) resting in said safety brackets (6), allow for a plurality of said bench seats (42) (43) positions thus producing a plurality of inclinable and declinable positions thus enhancing the degree of exercise performed by the user and reducing risk of injury to the user. 
     3. The horizontal sliding sleeves (32), nuts (35), and thumbscrews (36) allow horizontal type accessibility for both said bench seats (42) (43). Horizontal movement of said horizontal sliding sleeves (32) across said horizontal parallel bars (13) allows for a plurality of horizontal positions for said bench seats (42) (43) thus enhancing the exercise performed by said user and reducing risk of injury to said user, whereby, the improved seat adjusting sleeve assembly allows said user total freedom of horizontal and vertical positioning of said bench seats (42) (43) for any one of a plurality of different exercises for many different body parts of said user, thus enhancing the degree of motion during exercise by said user thus reducing risk of injury of said user, 
     (d) a seated row/curl attachment comprising: 
     (1) a &#34;u&#34; shaped adjusting angle (47) used for adjustments along said seat/row bar (44); 
     (2) two parallel plates (48) adjoined and centered on said adjusting angle (47) allowing variable effective distance between for row/curl pulley (49); 
     (3) a cable (50) of variable effective length, having first and second ends, passing through said row/curl pulley (49), each respective end having hookups consisting of cable crimps (18) and adjustable pins (19). 
     Advantage of seated row/curl attachment: 
     1. The seated row/curl attachment can be adjusted to a plurality of positions, with the aid of a pin, along said seat/row bar (44). The seat/row bar (44) can be positioned above or below said horizontal sleeves (32) by sliding up and down the said vertical seat/row sleeve (34), thus allowing said user to predetermine and affix said row/curl pulley (49) at the position desired in order to maximize the degree of motion desired during performance, thus enhancing the exercise motion and decreasing risk of injury, especially injury to the lower back of the user.
