I notice the same for gym stuff. I tend to go 8, 6, 3 for reps. 8 is kinda to remind me of the form and get going. 6 to introduce some challenge. And 3 to make sure we're really not leaving anything on the table.
Anywho, did a little GCN show workout at lunch and tossed a few 350w short efforts on the end of it. The aerobic work will pay off later. Once I swap back over, it'll just be a different kind of chewing your bar tape to cope with pain. 3min or 2min at a time instead of 8 to 20min.
It was one of those "random hiit" ones that's like 50min. With the new host.
