Actually the term "stacking" was used to describe the act of taking multiple types of steriods at the same time across the same cycle. Bodybuilders would typically "stack" 2-3 different roids, gradually increasing the dosage over say, 8 weeks, then again gradually decreasing the dosage back to minimal levels. By coordinating this with a carefully monitored diet and timed properly with upcoming contests it becomes a science to time your bodyfat down to "game day."

Lab, when I used to be working my heaviest, I too would go my own way with my training style. A lot of guys will tell you to combine chest & triceps, back and biceps (the Mike Mentzer way), as opposed to what I find works best, that being to train two totally different muscle groups together. I do Chest & back one day, and shoulders and arms the next. The reason for this is because once you work your chest to failure, you can't give your triceps a proper workout and you can actually end up overworking the secondary group. That type of workout is only good when you have a certain muscle group that is lagging and needs extra work, and there again you have to watch out for overworking.

What type of workout do you do? For reps, again, only after I've been training lightly for a few months to get back into it, once I'm back up to full swing I like to do about 3-4 different movements per muscle group. In each movement I'll usually do 3 to 4 sets, the first set is higher reps, the last set is only 2-4 reps and higher weight. From time to time I might try a single rep at the end with a slightly higher weight, but nothing that will risk injury. I guess that's more of an ego thing. (wanting to know how much you can do etc)

I finish off the heavy workout with like 3 sets of 50-100 crunches and more stretching. The warmup is 20 minutes on the stationary cycle and stretching.
