The accumulation phase went pretty well, added some muscle mass and corrected some imbalances while regaining some of the strength I had lost over the season when I could only lift once or twice a week due to matches.
I used an Upper/Lower split with 2 different sessions. I try to think more in terms of total time of the set rather than rep ranges, so one day I tried to keep the sets in the 10-25 second range (generally 4-6 reps for big movements, 8-12 for isolation stuff) and the other day I worked in the 45-60 second range (8-12 reps for big stuff and then I did isometrics in the 45-60 second range).
As for your questions:
1.) Remember that its not at all ME in the true sense of the word. I'm working with weights that are definitly not maximal and I'm trying to stop right before the set that I think will be difficult. It's almost more "Max Force" training since I'm focusing on moving the bar as fast as possible. It's the end of the first week and I'm definitly not feeling excess fatigue, in fact I think I could build up to higher frequency than this.
2.) It probably would be more effective if I waved the intensities (and thus the volume would follow), but right now I'm just trying to get a feel for how much frequency my body could handle. If you remember the "Wave-Loading" post, Brad Nuttal talked about it in there. That's what I have planned for the next time I go to intensification/higher frequency.
3.) I actually prefer to do the isometric emphasis when I'm doing more "accumulation" stuff. I like pairing a longer isometric with full-range reps, like bench press isometrics in the bottom position with a set of 8 for instance. For eccentric emphasis, that's actually what I'm building up to. I'm going to be doing a "power" block at the end of the summer that's going to be focusing on a lot of reactive and absorbtion work, right now I'm trying to build up my overall strength levels along with my nervous system.
I appreciate the comments.
