The Complete Guide to GZCLP: Programme Breakdown and How to Run It

GZCLP is the programme people get pointed to when StrongLifts or Starting Strength stops moving. It keeps the simplicity of linear progression but adds a release valve, so one bad session doesn't send the whole thing into a deload. That single design decision is why it survives longer than the programme most people run before it.

It's also what I'm running right now, with Cheryl on it too at a completely different strength level. I run the full session — T1, T2 and T3 — and keep my lunch breaks for a bit of extra isolation work on top. So this isn't a breakdown from the outside: it's how it's built, how to set it up, and where people trip up, written from inside the programme.

What GZCLP Actually Is

GZCLP is the novice variant of the GZCL method, built by Cody Lefever and shared originally on the r/gzcl community. The name is the method (GZCL) plus "LP" for linear progression.

The core idea is the tier system. Every session is organised into three tiers — T1, T2, T3 — and each lift in the programme progresses on its own clock. Fail your squats and your squats drop down a stage; your bench keeps climbing untouched. That independence is the main thing that separates it from a programme like StrongLifts, where a single missed lift can stall the whole session's progression.

I ran StrongLifts years ago and the thing that eventually killed it for me wasn't the weight — it was that one missed session forced a decision about the entire workout. GZCLP isolates that. A bad squat day costs me a squat stage, nothing more, and the rest of the week carries on as if it never happened. That's why it's stuck as my cornerstone where other programmes didn't.

It suits late-stage novices and early intermediates: someone with a few months of consistent training who has stalled on a pure linear programme, or who wants simple, autoregulated progress on the main lifts without RPE maths. If you've been lifting under three months, you don't need the complexity yet — finish a simpler linear run first.

The Tier System

Every training day is the same shape:

T1 — your main heavy lift. One of squat, bench, deadlift, or overhead press. Low rep, high intent. This is where strength is built and where the progression logic does its work.

T2 — a secondary compound. Higher rep, lighter than T1. Usually one of the big four in a supporting role. This is your volume.

T3 — accessories. Two or three movements, higher rep still, taken close to failure. This fills the gaps the main work leaves.

The tiers descend in load and ascend in reps. T1 is heavy and precise, T3 is light and accumulative.

How T1 Progression Works

T1 is a three-stage state machine. You start at the top and only move down when you fail:

Stage 1 — 3×5+ — three sets of five, the last set AMRAP (the "+" means as many reps as possible, with five as the floor).
Stage 2 — 6×2+ — six sets of two, last set AMRAP, two-rep floor.
Stage 3 — 10×1+ — ten singles, last set AMRAP, one-rep floor.

You add 2.5 kg every session you hit the target. When you miss, you drop to the next stage at the same weight — fewer reps per set, more sets — which buys you a few more weeks of progress before a reset. Fail the AMRAP on Stage 3 and you deload that lift 15% and go back to Stage 1.

The AMRAP last sets are the whole point. They tell you when you're ready to progress and when you've hit the wall, without you having to guess.

T2 and T3

T2 runs a parallel pattern at higher reps: 3×10 → 3×8 → 3×6, dropping a stage when you miss the last set's rep target, deloading 15% after the final stage. Same +2.5 kg per session when you hit.

T3 is rep accumulation. Two to three sets within a rep or two of failure, last set AMRAP. When your total reps across the sets reach 25, add weight next time. Don't grind T3 to true failure every set — that's not what it's for.

I keep T3 in the session, where it belongs — it's part of the programme, not an optional extra. What I add on top is a bit of isolation work at lunch, separate from training entirely: arms, side delts, calves, the bodybuilding bits GZCLP doesn't bother with. That's a personal add-on, not part of the programme, and it only works because the main session stays lean — a handful of barbell movements, in and out. If you want more isolation than GZCLP gives you, that's the way to do it: bolt it on in its own slot rather than stuffing the main session. GZCLP's job is the strength base, and it does that better when you don't bury it under twenty sets of curls.

The Weekly Split

GZCLP comes in two common shapes.

4-Day (the standard):

Day A — T1 Squat / T2 Bench / T3 Lat Pulldown
Day B — T1 Overhead Press / T2 Deadlift / T3 Dumbbell Row
Day C — T1 Bench / T2 Squat / T3 Lat Pulldown
Day D — T1 Deadlift / T2 Overhead Press / T3 Dumbbell Row

Each of the big four gets a T1 slot and a T2 slot across the week.

3-Day runs the same two day-templates alternating: A → B → A one week, B → A → B the next. Pick this if you genuinely can't make four sessions; four is the better default.

Setting Your Starting Weights

T1 should start around your five-rep max — roughly 87% of your estimated one-rep max. T2 starts lighter, about 65% of your T1 working weight. T3 accessories start light by design.

Undershoot all of it. Linear progression's entire value is the runway of easy sessions at the start; if you open too heavy you skip the part that builds the habit and burn your progression in a fortnight. Being conservative here is never the mistake.

Running It Across Two People

Cheryl and I are both on GZCLP, at very different strength levels, and that's where the design quietly earns its keep. Because every lift starts from your own numbers and climbs in fixed 2.5 kg steps, the same programme works for both of us without either of us touching the other's plan. Her squat and mine progress on the same logic and share nothing else.

The per-lift independence matters more when two people are running it, not less. A rough week for one of us doesn't drag a shared template around — each lift, for each person, sits at whatever stage it's earned.

The rest periods are what make it work as a pair. GZCLP's main work wants real rest between heavy sets, and when you train together that rest isn't dead time — one person's recovery is the other's working set. We alternate through T1 and T2 on the same bar and the prescribed rest falls out naturally, no clock-watching. Done this way the main session takes us 30 to 40 minutes together, which is the difference between a programme you keep and one that quietly dies because it never fit the evening.

Cheryl's loving it and feeling visibly stronger, which is the real test — the programme that works is the one you both still want to do in week eight. If you're training alongside a partner, this is one of the easier programmes to do it on: same structure, shared rest, completely separate progression.

We also keep each other honest through a shared VALDAKIN group — a private group where our sessions show up to each other with a leaderboard and the odd emoji when someone hits a PR. It's training data only, and it turns "did you train?" into something you don't have to ask. Two people on the same programme, each chasing their own numbers, with just enough visibility to make skipping awkward.

Common Mistakes

Treating T2 and T3 as AMRAP. Only T1 carries the "+" AMRAP marker on its last set. T2 and T3 are rep-target work. This one gets mangled constantly in copied spreadsheets — if your source has plus signs all over it, ignore them outside T1.

Adding 5 kg on lower-body lifts. Some communities recommend +5 kg lower / +2.5 kg upper. It works for a while and then it doesn't. Use 2.5 kg across the board to stretch the linear run; you can always override a specific lift later.

Swapping accessories every session. T3 is where people get bored and fiddle. Pick your accessories and leave them long enough to actually progress them.

When to Leave GZCLP

When your T1 lifts stall repeatedly even after a deload — you reset, climb back, and stall at the same place — you've taken what linear progression has to give. That's the signal to move to something with built-in weekly variation. nSuns 5/3/1 is the logical next step, and it's the programme this guide's predecessor was written for.

Running GZCLP in VALDA

GZCLP's per-lift state machine is exactly the kind of progression that's tedious to track on paper and trivial to get wrong in a spreadsheet — which stage is each lift on, what's the next weight, did that AMRAP clear the threshold. It's also how I track my own runs, and Cheryl's. VALDA models each lift's stage natively: paste the programme in, and the app tracks every lift's stage independently, calculates the next session's weights, and shows the prescription on the watch mid-set. I train; it keeps the state — which keeps the main session short enough that my extra lunchtime isolation work stays a bonus rather than the thing that gets cut.
