Whenever I'm designing a training template or routine specifications, I always place the most aggressively trained exercise and or the most "intensity" based exercise right in the beginning of the training week. This is one of the many lessons I've learnt from training under Eric Troy. Correspondingly, as the week progresses, I believe other superficial exercises may be added on and volume bumped up - but only towards the end of the week. Also, it is unlikely that the final sessions of the week will have very high intensity based workouts. I know a lot of strength trainees feel the need to throw in some arm work or side raises or something more "hypertrophy" based. Well, I'd still stick with the stand that getting too worked up about it is a waste, but if you absolutely must indulge yourself in this: do it on the last workout of the week. So, in short: do the heavy lifting first when you're most focused and "fresh" - both physiologically and mentally. Look forward to these training sessions and get absorbed in the process.
