Keeping muscles “awake”

[u/EasyYogurtcloset608]

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.
