I don’t know if I have ever heard a really good explanation on how we define “Volume”
When I was a competitive cyclist we had power meters that would record and download the exact effort (watts) put out during a ride. It was then downloaded into a software that had metrics based of what was called your FTP (functional threshold power) which was the max avg watss you can hold for 1 hour. This would be something like a 10 rep max on a lift. Then the software could give a TSS (training stress score) on each workout. Then you could use the software to manage training load and recovery. This was over 15 years ago but I bump into a current Pro cyclists from time to time and they still use the same software. It’s always funny to see their surprise when they hear me talk about this seeing as how I’m 230lbs now and raced bikes at 155lbs.
If you read all that, the reason I mention that is I feel that when we are taking about “Real Volume” it is not how many sets or even how many “working sets” but really how much effective training stress did we put on ourselves during the workout.
I feel like I train pretty low volume but I do probably 6-10 hard working sets per workout and I have a 3 day split with two days off per week so I hit everything on average 2x every 8 days.
What I do to to eliminate what some might call junk volume is I do really low reps on my warm up sets for my first big lift and after I’m primed and warm I will usually just jump to working sets or at the most do one feeder set at like 6 reps. Most working sets for me are in the 8-12 rep range. I’m 47 and my joints are my limiting factor
For example back workout yesterday started with nuetral grip pull down
90 x 12
130 x 8
170 x 6
200 x 4
260 x 11
260 x 9
Then went to chest supported dumbbell row and went straight to the 120s x 10 for two working sets
I’m no expert but I do feel like I’m doing really good for someone my age with the key being balancing pushing as hard as possible while not getting injured.
