Hey - I read through this all the way through - Great post, took me awhile - anyways - my only question would be this....Are you a believer in switching up your workouts in each body part every 6-8 weeks (or a given time frame)...i.e. if you have been doing bench and incline bench for chest, switch to decline bench and flies every 6-8 weeks and cycle them? or Do you pretty much stick with one workout?
My personal belief is to stick to an exercise until I am seeing no results. I will then try to change things by adding or deleting sets or reps or just change when I do it in the workout or take less/more time between sets. If then I am still getting no results then I change that exercise out for something different. If something is working why change it just because you've set a time limit? If you are still making gains then your body hasn't adapted to the exercise as of yet.
