GZCLP: The Linear Progression That Plans for Failure

GZCLP is a beginner linear progression by Cody Lefever (GZCL) with three tiers per workout: a heavy T1 lift (5 sets of 3), a moderate T2 lift (3 sets of 10), and a light T3 accessory (3 sets of 15+). You add weight every session. When you miss reps, you switch to fewer reps per set at the same weight instead of deloading. That is its strength, and its blind spot. See every major program and where it stalls.

What is GZCLP?

GZCLP is the novice version of the GZCL Method, a tiered way of training where each workout has a heavy main lift (T1), a lighter volume version of another main lift (T2), and a high-rep accessory (T3). It rotates four workouts, trains the squat, bench, deadlift, and overhead press as both T1 and T2, and adds weight every session.

Cody Lefever introduced it in a 2016 post on Swole at Every Height for novices familiar with classic linear progressions. GZCL is the overall training method; GZCLP is the beginner program built around it. Lefever writes reps × sets, so his “3×5+” means 5 sets of 3.

The plus sign means the final set is performed for as many reps as possible (AMRAP), while stopping short of failure. Rep totals in parentheses are the base volume: the reps prescribed before the final set’s extra reps.

How is GZCLP laid out week to week?

There are four workouts. Day 1: squat T1, bench T2, lat pulldown T3. Day 2: overhead press T1, deadlift T2, dumbbell row T3. Day 3: bench T1, squat T2, lat pulldown T3. Day 4: deadlift T1, overhead press T2, dumbbell row T3.

Run the workouts four days a week or cycle them over three days, leaving at least one rest day between sessions. Lefever’s example is Week 1: A1, B1, A2; Week 2: B2, A1, B1. Rest 3–5 minutes for T1, 2–3 minutes for T2, and 60–90 seconds for T3.

How does progression work on GZCLP?

Add weight each session you hit the required reps: 5 lb (about 2.5 kg) on bench and overhead press, and 10 lb (about 5 kg) on squat and deadlift, according to The Fitness Wiki. Lefever caps novice jumps at 5–10 lb (2.5–4.5 kg); T3 moves up only when the last set reaches 25 reps.

1. T1: Start at 5×3+, then move through 6×2+ and 10×1+ if you miss the target. Base volume falls from 15 to 12 to 10 reps.
2. T2: Start at 3×10, then use 3×8 and 3×6 after misses. Base volume falls from 30 to 24 to 18 reps.
3. T3: Do 3×15+, adding weight once the final set reaches 25 reps. Learn what AMRAP means and how hard to push it.

Lefever says to stop AMRAP sets 1–2 reps short of failure. A meta-analysis found no significant difference between training to failure and stopping short for strength (effect size −0.09) or hypertrophy (0.22), so grinding every final set adds fatigue without a demonstrated need (Grgic et al., 2022).

What happens when you fail a set on GZCLP?

You change the rep scheme, not the weight. On T1, missing 5×3 moves you to 6×2, then 10×1 at the same load. Fail that, rest two or three days, test a new 5-rep max (5RM), and restart at 85% of it.

1. T1 failure ladder: 5×3+ → 6×2+ → 10×1+ → rest 2–3 days → test 5RM → restart at 85%.
2. T2 failure ladder: 3×10 → 3×8 → 3×6 → restart at 3×10, using the last Stage 1 weight plus 15–20 lb, as summarized by The Fitness Wiki. Lefever says the increase should be no more than 20 lb (9 kg).

StrongLifts instead repeats a failed weight up to three times, then cuts it by about 10% and has you rebuild (StrongLifts failure guide). GZCLP keeps you practicing under the same load while reducing reps and fatigue.

Where does GZCLP stall, and how can you tell?

GZCLP stalls when a full T1 cycle ends and your new 5RM is no better than the last one. The stages can keep you busy for weeks at one weight, so the 5RM test is the scorecard: if it rises, you’re progressing; if it is flat twice, linear progression on that lift is finished.

Overhead press and bench often stall first because the lifts are smaller and even modest jumps are large relative increases. T2 squat and deadlift sets can also become taxing as 3×10 gets heavier. Ask yourself:

• Did your latest 5RM beat the previous test?
• Does T2 restart at a heavier weight each cycle?
• Are T3 AMRAPs still climbing toward 25 reps?

Flat bodyweight, short sleep, or taking every AMRAP to grinding failure can look like a programming stall. If your 5RM retest came back flat, the program may be done—or something outside it may be the bottleneck. Find out which bottleneck is first.

GZCLP vs StrongLifts 5x5: which handles stalls better?

GZCLP handles stalls better. StrongLifts 5x5 repeats a failed weight three times and then drops it by about 10%, while GZCLP keeps the load and lowers reps per set. It also adds T2 and T3 work for more weekly volume than 5×5 alone.

On a four-day rotation, each main lift gets about 8 weekly sets: 5 T1 sets and 3 T2 sets. StrongLifts gives bench and overhead press 7.5 sets and squat 15. GZCLP also provides 6 weekly sets each of pulldowns and rows, useful upper-back work.

More weekly sets are associated with more muscle growth, with a graded dose-response of about 0.37% gain per additional weekly set (Schoenfeld et al., 2017). See how many sets per muscle per week when comparing your total training volume.

What should you run after GZCLP?

Lefever’s advice is to complete two to three full cycles, then add volume from the bottom up—more T3 and T2 work—and move toward a fuller GZCL program (Swole at Every Height). When a lift’s 5RM retests stop rising, move it to weekly progression instead of restarting GZCLP again.

• If strength is your priority: Move to an intermediate GZCL-method program or Wendler’s 5/3/1.
• If size is your priority: Choose an upper/lower split with more sets per muscle.
• If you are still moving through a cycle: Finish it and judge progress by the next 5RM test.

If the retest is flat, it helps to separate a true programming stall from recovery or another bottleneck. Take the quick, one-tap diagnosis to identify what may be holding your progress back.

FAQ

What is GZCLP?

GZCLP is a novice linear progression created by Cody Lefever (GZCL). Each workout has a heavy T1 lift (5 sets of 3), a moderate T2 lift (3 sets of 10), and a light T3 accessory (3 sets of 15+). You add weight each session, then change to fewer reps per set at the same load when you miss reps.

What is the difference between GZCL and GZCLP?

GZCL is Lefever’s overall training method, built around heavy, moderate, and light tiers in each session. GZCLP is the simple linear progression he designed to apply it to novices. After two to three full cycles, his advice is to add volume and move toward a fuller GZCL approach (Swole at Every Height).

How does GZCLP compare to StrongLifts 5x5?

Both add weight every session. StrongLifts uses 5×5 and drops the load about 10% after three failed sessions; GZCLP keeps the weight and changes the scheme from 5×3 to 6×2 to 10×1. Its pulldowns, rows, and T2 work also give you more volume for muscle size.

Is GZCLP a good program?

For a novice, yes: it is one of the better-designed beginner progressions because it plans for missed reps. Its main risk is hiding a stall, so judge progress by the 5RM test at the end of each T1 cycle, not by stage changes. If two retests in a row are flat, that lift has finished linear progression.
