EHHHHHHH!!!!! WRONG!!!! Don't even try to down play 47 sets, just say thank you I guess I do kick some ass in there don't I?It was 90 minutes -but I had to coach my daughter between sets too. Some of those workouts I do in circuits, like Bradford/Rear delts.
You do 9,000 warmups & stretches, I bet it consumes some energy, I do none. I read some studies about warmup and stretches, all were inconclusive, as athletes injured themselves equally, with warmup and without. So I hardly do, maybe only if I have a nagging elbow pain and warm it up before going heavy. I stretch a little bit after workout, mostly jumping up and let myself hang by my arms to stretch.
Edit: Ah, and when you look at my weights used, I go not as near as heavy as you, guessing that enables me to do more volume.
Curious on your reps, how many reps would you say you are leaving in the tank on your work sets. Like if you had to keep pushing, and weren't stopping short of form failure. I could probably do volume like this if I avoided anything over an RPE8 IE... 2-4 reps left in the tank. Much over that and I would break within a week or two.
