In Beyond 5/3/1 there is a program called 5/3/1 Frequency Project and 5/3/1 Frequency Project 2.0. Also in Beyond 5/3/1 there are multiple templates ranging from 3 days a week to 7 days a week. You can choose one of those templates. There is a lot of auto regulation in Beyond 5/3/1 so you really have to know what's best for you. There are 11 different training schedules.
Your best bet, being that this is the first time you've started 5/3/1, is to follow a 4 day a week training schedule with an old familiar template. You are probably looking at 5/3/1 and asking yourself "is this really enough to get bigger and stronger?"
This is not a program for you if your goal is to look good in a speedo. This is a performance program and some of the side benefits of 5/3/1 are that you will be stronger and bigger.
"I want to get shredded but strong as fuck" is not a goal. If you want to get shredded you will not be able to eat to get strong as fuck, and if you want to get strong as fuck, you need to eat like it, and you wont get shredded.
If you want to get strong but lose some body fat, you should dial back the volume and train for strength while eating to lose fat, but not lose strength. That's one of the hardest things to do in weight training.
Pick 1 goal:
A: lose fat
B: get strong
C: bulk up
D: run a 5K under 25 minutes
E: bench my bodyweight for 10 reps
Now I'm just making shit up...
My suggestion is to try 5/3/1 for a straight year. Do 5/3/1 4 days a week, hard conditioning two days a week, do mobility 1-2 times a day, every day. Walk 2 miles 4 days a week. Pick a simple template to start out with like the Triumvirate and run it a couple cycles, then try BBB or FSL or up/down ladder. You can do FSL 5x5 of FSL rest/pause; it really doesn't matter. My point is, there are so many programs/templates to chose from, just pick one, run it for a few cycles, then pick another and run it for a few cycles. If you don't like the results you're getting, change diet, volume, conditioning, etc... learn what works for you and do it.
5/3/1 is all about habits, starting off too light, progressing slowly, and programming for life. Don't reinvent the program - do it as written. There are no hypertrophy days and strength days in 5/3/1, although there are phases in some of the programs/templates in the books.
