I workout at my gym at work which is limited in weights, machines, etc. The dumbells only go to 100's. My buddy and I are doing 6 sets on flat bench now getting over 10 reps so I don't think the 100's are doing us any good anymore. We also do incline where we use 95's after that and then we do 1 arm flat. There is no regular barbell bench in the gym. We finish our chest workout with some cable curls. Does anyone have any suggestions as to what we could do in there to keep bulking. For example for pullups we wear a bookbag with 50's inside it and on lat pulls we stack the machine up with dumbells to get an extra 150 lbs. We pretty much rigged everything but I don't see anyway to rig chest exercises.

Thanks in advance.
