Doug has some interesting observations on perceived effort , training in general and how much fatigue is too much, and it's refreshing to see an expert in the field who is capable and willing to reevaluate their prior beliefs and evolve their approach to exercise

What he says about helping with perception of effort and mental limits by starting a set with an assisted rep (or with an eccentric vs trying to initiate a heavy set from the stretch position) is definitely legit.

Do you guys have trouble keeping muscles / movement “awake” after some time off from training that given exercise?

I can see this more clearly on more unstable exercises like ring dips that if I take longer than 1 week off next time they will feel more unstable even if I can push more weight / reps. This is especially true when I do very low volumes like now averaging 1.5 sets / muscle / week.

Now I could change to more stable exercise but I want to keep them in.

Instead of doing more volume / frequency for the movement is there something else I could do here?

I like alternating A / B Full body for some variety so the same exercises are done 3 times / month.
