     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring  FIGS. 1 and 2  of the drawings, a boxing upper cut training bag assembly  10  of the invention can be seen mounted on a suspended boxing heavy bag  11 . In this example, the heavy bag  11  has a main cylindrical padded body member  12  suspended by multiple straps  13  to a central support line  14 , interengaging and extending therefrom as will be well-known and understand by those skilled in the art. 
     The training bag assembly  10  of the invention has one or more independent target punching bags  15 , each pivotally secured by an annular mounting bag strap  16  that adjustably extends around the cylinder body member  12  of the heavy bag  11 , as best seen in  FIG. 1  of the drawings. Each of the independent target punching bags  15  is of a generally rectangular outside configuration within this example fabric mounting loops  17  thereon, thru which the suspension bag strap  16  extends allowing each target punching bags  15  to move independently during impact, as will be described in greater detail hereinafter. 
     The target punching bags  15  are filled with padding and may have a selective interchangeable weight W illustrated in broken lines encapsulated there within, depending on the user&#39;s preference. 
     The target punching bag  15  has an access closure opening at  18 , best illustrated in  FIG. 5  of the drawings, with hook and loop fasteners A and B on oppositely disposed surfaces which provide for weight W access for interchangeability as discussed. 
     It will be seen that each of the target punching bags  15  has an attached spacing element  19  that extends therefrom, so as to be engaged against the punching bags  11  mounting surface  11  to hold the target punching bag  15  in annular space-relation thereto. Such bag spacing provides a proper upper cut training target for the user (not shown) but in use as seen in  FIG. 6  of the drawings. Each of the target punching bags  15  has an attachment loop  21  through which a resilient return cord  22  extends around the heavy bag  11  in vertically spaced parallel relation to the hereinbefore described mounting bag strap  16 . The return cord  22  is adjustably secured so as to impart varying elasticity by foreshortening about the heavy bag  11  by interadjustable fastener  22 A as seen in  FIG. 3  of the drawings. 
     The resilient return cord  22  is so positioned to resiliently retain the target punching bag  15  against the bag&#39;s mounting surface  20 , and therefore selectively return the target punching bag  15  thereto after being hit and pivotally displaced during use, as indicated by the broken lines and directional force arrows in  FIG. 6  of the drawings. 
     Multiple height adjustable suspension straps  23  extend from each of the target punch bags  15  of the training bag assembly  10 , utilizing an access fitting  23 A through an attachment loop  23 B securing to the bag and extends up to a primary attachment ring fitting  24  which is releasably secured on to the bag suspension support  14  of its vertical tether. 
     It will be evident from the above description that by selectively adjusting the adjustable suspension straps  23 , each of the target punching bags  15  and correspondingly the training bag assembly  10  can be positioned at a vertical height on the suspended heavy bag  11  to correspond with the (user&#39;s) height requirement to achieve a proper upper cut practice in the sport of boxing. 
     Correspondingly, referring to the training bag assembly&#39;s annular mounting bag strap  16  is secured around the heavy bag  11  by into an attachment fitting  26  to facilitate the adjustable attachment thereto, and in this example may have a protective cover flap F that would overlie the fitting so as to protect same from direct contact by the boxer, which may occur during a workout. 
     It will therefore be seen that during use a boxer (not shown) selects the selective target punching bag  15 , as illustrated in broken and solid lines in  FIG. 6  of the drawings, so as to practice boxing “upper cut” punches. The target punching bag  15  upon impact by the boxer will pivot upwardly on the attachment strap  16  as illustrated in broken lines and force arrow FA and then resiliently return to the pre-punch position against the heavy bag surface  20  automatically by the resilient restraint of the hereinbefore described retainment cord thus repositioning the target punching bag rapidly for another hit. 
     By having multiple target punching bags  15  spaced annularly around the perimeter of the suspended heavyweight bag  11 , a more natural and affective workout can be achieved as the user, and to some extent the bags  15  move about providing for a more realistic training simulation. 
     Referring again to  FIG. 6  of the drawings, an alternate resilient bag retaining element  27  can be seen in broken lines, which are the functional equivalent of the elastic cord  22  and be connected directly to the back of each of the independent target punching bags  15  of resilient material as opposed to the continuous elastic cord  22  as hereinbefore described while achieving the same effective automatic return during use. 
     Referring now to  FIG. 7  of the drawings, an alternate boxing upper cut training bag assembly  30  can be seen, wherein the multiple target punching bags  15  and basic mounting and resilient structures are identical to that of the primary form of the invention with an alternate bag support attachment  31  provided to fit on non-unsuspended self-supporting workout bag  32  as illustrated. The alternate support attachment  31  has in this example a pair of right angularly crossed bag engagement bands  33  and  34  that extend from oppositely disposed attachment points from an annular bag attachment strap  34 . This arrangement can therefore be placed over the top  36  of the self-supporting workout bag  31  as seen with corresponding multiple target punching bags  38  pivotally secured thereto as hereinbefore described. 
     It will be apparent that the number and positioning of the individual target punching bags  15  can be varied as well as the hereinbefore described adjustability imparted to the structure that affords a variety of adjustments to accommodate bag attachment variations inherent therewithin, and therefore that respective training bag assemblies  10  and  31  provide a number of user attachment scenarios and thus viability and usability in multiple environments. 
     It will therefore be seen that a new and novel fuel training bag attachment assembly  10  has been illustrated and described, and will be apparent to those skilled in the art that various changes and modification may be made thereto without departing from the spirit of the invention.
