4-day powerlifting split: a free 8-week program with your weights

This is a complete 4-day powerlifting split: four sessions a week, eight weeks long, with every set written as a percentage of your one-rep max. Put your squat, bench, and deadlift maxes into the calculator above and it turns those percentages into the weight on the bar for each week.

It is built for lifters who have finished a beginner program — linear progression has stalled, and you can reliably train four days a week. If you’re still deciding between three and four days, read 3-day vs 4-day powerlifting split first. If four days is settled, this is the program.

The week at a glance

Each competition lift is trained three different ways every week: once for volume, once paused for technique and speed, and once heavy with an AMRAP (as-many-reps-as-possible) set that decides how fast you progress.

Days 1–3 have two main lifts each, which keeps them short — typically 45 to 60 minutes with warm-ups. Day 4 is the long one: three heavy lifts, each finishing with an AMRAP set.

This structure is called daily undulating periodization (DUP): the reps and intensity change from day to day instead of week to week. Each day hits a different quality, so you can train every lift often without every session being a heavy grind.

The full 8 weeks

The program runs in two three-week loading blocks, each followed by a deload week.

• Weeks 1–3 (Base): moderate weights, higher reps. Volume work is 4×8, pauses are 5×3, and Day 4 tops out with sets of three.
• Week 4 (Deload): around 50–60% for a few easy sets. No AMRAPs.
• Weeks 5–7 (Intensify): heavier, fewer reps. Volume work drops to 4×5, pauses to 5×2, and Day 4 moves to doubles.
• Week 8 (Deload): same as week 4.

Inside each loading block, every percentage goes up by 2.5% a week. Here’s the whole program as percentages of your 1RM:

Paused lifts use the same max as their competition version: paused squat runs off your squat 1RM, paused bench off your bench, paused deadlift off your deadlift.

How progression works: the Day 4 AMRAP

The AMRAP set at the end of each heavy lift on Day 4 is the program’s steering wheel. Do the two prescribed sets, then take the third set for as many clean reps as you can — leaving one rep in reserve, and stopping the moment form or bar path breaks down.

What you get decides the next week’s max for that lift:

Below the threshold, the max stays where it is — next week’s percentages still climb 2.5% as written. That’s the whole system: the weekly climb is built in, and a strong AMRAP adds to it on top. A bad day doesn’t cost you anything except the bonus.

Two rules keep the AMRAP honest:

1. Reps have to be competition-standard. Squats to depth, bench touched and pressed, deadlifts from a dead stop. A grinder with a hitched lockout doesn’t count. If you want a refresher on standards, see powerlifting squat depth.
2. Leave one in the tank. The AMRAP is a test of your current strength, not a max-effort event. Going to true failure every week on three lifts turns Day 4 into the thing that wrecks Day 1.

Picking your starting maxes

The calculator needs a one-rep max for each lift. Use a real, recent number — something you’ve lifted in the last couple of months with competition-standard form.

• No recent 1RM? Take a recent hard set of 3–5 reps and run it through the one rep max calculator.
• Max is old, or you’re coming back from a break? Enter a number about 5% below what you think it is. The AMRAPs will push it back up within a couple of weeks if you underestimated — that’s what they’re for.
• Not sure between two numbers? Pick the lower one. Starting light costs you a week or two. Starting heavy costs you the block.

Scheduling the four days

The order matters more than the weekdays. Day 3 (paused bench, paused deadlift) leaves your back tired, and Day 4 is your heaviest session, so give yourself a rest day before Day 4 whenever you can.

Schedules that work:

• Mon / Tue / Thu / Sat — the rest day before Saturday’s heavy session makes this the best default.
• Mon / Tue / Thu / Fri — the classic upper-lower rhythm. Fine, but Day 4 comes straight after Day 3.
• Sun / Mon / Wed / Fri — for lifters whose weekend is free but Saturday isn’t.

If you miss a day, push the week back rather than doubling up. Running Day 3 and Day 4 together is more fatigue than either session is designed for.

Accessories (optional)

The program prescribes only the competition lifts and their paused variations — that’s the work that drives your total. If you have time and energy left, add two or three accessories at the end of Days 1–3:

• Day 1: rows or pull-ups, plus a triceps movement
• Day 2: a single-leg movement (split squats, lunges) and hamstring curls
• Day 3: upper-back work and a core movement

Keep them at moderate effort — two or three reps short of failure. If your Day 4 numbers start dropping, cut accessories before you cut main-lift sets. Powerlifting accessory exercises covers what to pick and why.

Deload weeks: don’t skip them

Weeks 4 and 8 feel too easy. That’s the point. Three weeks of rising percentages and weekly AMRAPs accumulate fatigue that hides your real strength; the deload lets it clear so the next block starts from a higher base. Deload weeks explained goes into why the easy week makes the hard weeks work.

After week 8

You have two good options:

1. Run it again with your new maxes. Everything the AMRAPs added carries over, so the second run starts heavier than the first.
2. Move on to a block program with longer hypertrophy, strength, and peaking phases — the natural next step once weekly AMRAP progress slows down. If you have a meet coming up, peaking for your first meet covers the final weeks.

Other ways to set up a 4-day split

This program is one structure. Two others are common:

• Upper / lower: two upper-body days and two lower-body days, usually one heavy and one lighter each. Simple and good for bench volume. There’s a sample in the 3-day vs 4-day split post.
• Conjugate-style: max-effort lower, max-effort upper, dynamic-effort lower, dynamic-effort upper, with the main exercise rotated every week or two. Powerful, but it relies on picking the right variations — harder to self-program.

The DUP layout above is the easiest of the three to run without a coach: every lift is trained three times a week, percentages tell you exactly what to load, and the AMRAP takes care of progression.

Who this split isn’t for

• Beginners. If you can still add weight every session, do that — it’s faster. Start with a beginner strength program and come back when linear progress stalls.
• Lifters who can’t protect four days. A 4-day program you complete three days of is worse than a 3-day program done every week. Powerlifting for busy professionals has a 3-day alternative.
• Lifters over 40 with recovery problems. Four days can work well after 40, but watch Day 4. If AMRAPs stall for two blocks in a row, see the best powerlifting program over 40 for lower-frequency options.

FAQ

Is a 4-day split good for powerlifting?

Yes, for intermediate lifters with four reliable training days. It lets you train each competition lift more than once a week while keeping individual sessions short. Whether it beats a 3-day split depends mostly on whether you’ll actually complete all four sessions.

How long are the sessions?

Days 1–3 usually take 45–60 minutes including warm-ups. Day 4, with three heavy lifts and three AMRAP sets, often runs 75–90 minutes. Add 10–15 minutes if you do accessories.

Why is the same lift trained three times a week?

Each exposure trains something different: volume builds work capacity and muscle, pauses build position and speed out of the hole or off the chest, and heavy work builds strength. Spreading them across the week means none of them has to be done tired.

What if I fail the prescribed reps (not the AMRAP)?

Finish the session and leave that lift’s max where it is — one bad day is noise. If you miss prescribed reps on the same lift two weeks in a row, the max is set too high: lower it by about 5% and carry on with the program.
