ANNEX RACK SYSTEM
Our Modular Annex Rack offers all 
the features of an Olympic station 
with the ability to add storage and 
connect additional units as a facility 
expands and evolves. 
Storage of weight plates, dumbbells, kettlebells, and 
medicine balls is contained between the two half 
racks to eliminate the need for stand-alone weight 
storage racks while keeping your essential training 
tools close to the workout area. 
This unique integration of Olympic racks and storage 
systems maximizes utilization of available training 
space. Training stations come standard with many 
features plus a wide variety of attachments to fulfill 
every site and station need. 
Versatility and customization have 
lost their way in the fitness industry, 
but STAK Fitness in collaboration with 
Dynamic Fitness and Strength is bringing 
it back with the M
3
 Zone Series. 
Choose a standard set up or customize your own for your space. Add 
attachments from 20+ options, interchange them at any time. Color 
customize any part of the unit. The M
3
 Zone possibilities are endless.
Training trends change, so your equipment should be able to change with 
them. The M
3
 Zone also allows for complete walk through of the unit, no 
more large machine foot print staking up space in your functional facility.
Units come with 3’’x3’’, 11 gauge steel uprights. Precision laser cut 
numbering system to easily adjust attachments. Steel shot blasted and 
washed for ultimate paint adhesion to make your M
3
 Zone Group Trainer 
look brand new for years to come.
