i think lateral raises would make sense, but after pull ups i don't want to do biceps curls for example, cause the biceps are already fv(k up.
Curls after pull ups actually do make sense. You've already started to fatique them. They may not have been completely fatiqued since you use other muscles as well. This means it takes very little extra to fully work your biceps. Then they're fully rested the next time you come back to pull ups. Lateral raises might work best after OHPs, for the same type of reason.
your approach is good. when i was doing isolations, i was always doing another exercise which focuses on other muscles between for example shoulder press and lateral raise, cause you are obviously able to work more weight then. but i think your approach of more fatigue could be better.
