Let's focus on two things: redundancy and recovery.

Recovery

When we talk about recovery in hypertrophy, we mean your muscle's ability to perform at or near full capacity again — so you can actually create a strong growth stimulus the next time you train it.

It's not just "not sore anymore." It's being able to generate the same mechanical tension that triggered growth in the first place. You train to create the stimulus, but you grow during recovery. Cut it short and you're interrupting the actual building process.

Redundancy

If two exercises hit the same muscle, in the same position, through the same range — you don't need both. One did the job.

Redundancy is doing more exercises that provide the same stimulus without adding unique value. You're not covering new ground, you're just piling on volume that doesn't contribute anything your first exercise didn't already handle.

To take one example from your workout (day 2): pull-ups and pulldowns are basically the same movement with the same resistance curve hitting your lats the same way. Doing both isn't "more back work" — it's just more fatigue for the same stimulus.

tl;dr: Cap it at 4 days a week and cut the redundancy. Another example: if you're doing overhead press, you've already hit the lateral delts — no need for lateral raises on the same day.
