So I tried something different tonight - stuward recommended 5 minutes rest. I did that, and cut down from 3x5 to 2x5 for all my exercises to keep the time of the workout almost the same (in fact, slightly shorter, since I don't rest 5 mins between different exercises). So only 2/3 of the work, and longer rest times, and heavier weights.
Last week: 3x5x112.5kg broken pace on the sets.
This weel: 2x5x115kg, steady pace (rep-deweight-stand and reset-rep)
I was able to increase my bench press a couple kilos for the same reps, keep my shoulder press the same weight but get all 5 reps smoothly instead of struggling on the last rep (I'll up it next time), and up the weight on my dumbbell rows too.
I kept in mind that my goal was to make all 5 reps, rest 5 minutes, make 5 more, and then stop, and no worry about pacing...and the result was a better pace. I think I can keep adding to the deadlift for a while on this approach. So I'm going to keep doing this - 2x5 with 5 minutes rest.
Thanks as always,
