Help me optimize my split please.

I like it. I was worried only hitting everything once a week would be too little volume. I've been making good progress so don't want to take a step back.

How tall are you bruh?

Ughh, don't wear heels, you'll shorten yer Achille's tendon and yer deadlift will suck arse!

In my mid-40s and mostly use a 4-day 531 schedule but no matter what plan I use I found I have diminishing returns on my workouts after lifting more than 3 days in a row. I know everyone is different, but this wasn't an issue when I was younger. You don't need to take a true rest day, if I have a week where my schedule only allows me 4 straight days to get it in, I will double up on day 2, then program a mobility day with very light lifting and a maybe a long row on day 3, then finish up day 4 with my normal planned workout.

If I try to power through by Day 4, no matter what main lift or bodypart I'm focusing on, I'm not as strong and worse, less focused. I also find this approach keeps me healthier, I haven't hurt or tweaked anything during workouts in a long time. That might also be a focus on better form and mobility, but it all adds up.

M chest, hit a great tricep superset at the end
Tu lats/traps
W legs/glutes
Th shoulders (35-45 min workout)
Fri bi’s/tri’s

I’ve been on this split for about a year and I’m sore each and every time. Have had great growth. Hour a day. 4-5 exercises, 4-5 sets each, 15-18 reps each set.

*hypertrophy is my goal

I edited. I rest 0:45-3:00 depending.
Mostly 0:45-1:00 but I’ll sometimes do heavier weight (2-5 reps) last set and rest 3:00 before.
