GZCLP is one of the most recommended beginner-to-intermediate powerlifting programmes on the internet — and for good reason. Created by powerlifter Cody Lefever (username GZCL on Reddit), it uses a three-tier training structure that develops strength across all major lifts simultaneously while building significant volume. If you’ve finished a basic linear progression programme (Starting Strength, StrongLifts 5x5) and want a structured next step, GZCLP is one of the best options available. This is the complete guide.

📋 What Is GZCLP?
GZCLP stands for GZCL Programme for Linear Progression. It is a specific application of Cody Lefever’s broader GZCL training method, adapted for linear progression — meaning you add weight every session as long as you hit your rep targets. The GZCL method itself is documented on Lefever’s blog (Swole at Every Height) and has been widely adopted in powerlifting communities.
The key innovation of GZCLP over simpler linear programmes like Starting Strength is the three-tier structure — you train multiple lifts at multiple intensities in every session, building both strength and volume simultaneously.
🎯 The Three-Tier Structure — The Core Concept
GZCLP’s three-tier structure: T1 (heavy), T2 (moderate), T3 (light/accessory)
Every GZCLP session contains three tiers of work:
| Tier | Intensity | Rep Scheme | Purpose |
|---|---|---|---|
| T1 | High (85–95%) | 5 sets of 3, last set AMRAP | Max strength development |
| T2 | Moderate (65–75%) | 3 sets of 10 | Hypertrophy, volume accumulation |
| T3 | Light (50–60%) | 3 sets of 15+ | Accessory work, weak point training |
This structure is supported by research on concurrent strength and hypertrophy training. Schoenfeld (2010) in the Journal of Strength and Conditioning Research demonstrated that training across multiple rep ranges and intensities produces superior adaptations compared to single-rep-range training.
💪 Tier 1 — Main Lifts
T1 is the heaviest work of the session. The rep scheme is 5 sets of 3 reps, with the final set performed AMRAP. This is your primary strength stimulus.
T1 lift rotation across the 4-day programme:
- Day A: Squat (T1)
- Day B: Overhead Press (T1)
- Day C: Deadlift (T1)
- Day D: Bench Press (T1)
Progression: Add 10 lbs to squat/deadlift and 5 lbs to bench/OHP each session. If you fail to hit 5 reps on the AMRAP set for two consecutive sessions, reset to 5 sets of 3 at a lower weight, then progress to 6 sets of 2, then 10 sets of 1 before resetting weight.
📊 Tier 2 — Secondary Lifts
T2 is moderate-intensity volume work. The rep scheme is 3 sets of 10 reps. T2 lifts complement the T1 lift of the day:
- Day A: Bench Press (T2) after Squat (T1)
- Day B: Deadlift (T2) after OHP (T1)
- Day C: OHP (T2) after Deadlift (T1)
- Day D: Squat (T2) after Bench (T1)
Progression: Add 5 lbs to squat/deadlift and 2.5 lbs to bench/OHP each session. If you fail to complete all 30 reps across 3 sets, repeat the weight next session.
🔧 Tier 3 — Accessories
T3 is light accessory work. The rep scheme is 3 sets of 15+ reps. Choose 1–2 exercises that address weak points or support the main lifts:
- Lat pulldowns, cable rows, face pulls
- Dumbbell press, tricep pushdowns, bicep curls
- Leg press, leg curl, calf raises
- Core work: planks, ab wheel, hanging leg raises
🗓️ 4-Day Training Schedule
| Day | T1 | T2 | T3 |
|---|---|---|---|
| A | Squat 5x3+ | Bench 3x10 | Lat pulldown 3x15+ |
| B | OHP 5x3+ | Deadlift 3x10 | Dumbbell row 3x15+ |
| C | Deadlift 5x3+ | OHP 3x10 | Leg press 3x15+ |
| D | Bench 5x3+ | Squat 3x10 | Face pulls 3x15+ |
Run A, B, C, D across 4 consecutive training days, then rest. Repeat. Most lifters train Monday–Thursday or follow a 4-on/1-off rotation.
📈 Progression — How to Add Weight
| Lift | T1 Increment | T2 Increment |
|---|---|---|
| Squat | +10 lbs/session | +5 lbs/session |
| Deadlift | +10 lbs/session | +5 lbs/session |
| Bench Press | +5 lbs/session | +2.5 lbs/session |
| OHP | +5 lbs/session | +2.5 lbs/session |
When you fail to hit the AMRAP target on T1 for two consecutive sessions, progress through the rep scheme: 5x3 → 6x2 → 10x1, then reset weight by 10–15% and restart at 5x3.
👟 Footwear for GZCLP
GZCLP trains squat, deadlift, bench, and OHP across all four days. Footwear considerations:
- Squat T1 and T2 days: Weightlifting shoes with 20mm heel recommended for high-bar squatters and beginners with limited ankle mobility. Consistent footwear across T1 and T2 squat sessions is important for technique development.
- Deadlift T1 and T2 days: Flat shoes or deadlift slippers. Minimal heel elevation reduces bar travel distance.
- Bench and OHP days: Any flat shoe with a stable base.
For beginners on GZCLP, investing in a pair of weightlifting shoes early establishes good squat mechanics from the start. See our Best Squat Shoes 2026 — USA guide for recommendations at every price point.
✅ Honest Pros & Cons
| Pros | Cons |
|---|---|
| ✅ Trains all four main lifts every week | ❌ More complex than Starting Strength or StrongLifts |
| ✅ Builds strength and hypertrophy simultaneously | ❌ 4 days/week required — not ideal for 3-day schedules |
| ✅ Built-in progression system with failure protocol | ❌ Sessions can run 60–75 minutes |
| ✅ Free — no book or app required | ❌ No built-in deload — add manually every 8–12 weeks |
| ✅ Excellent bridge from beginner to intermediate | ❌ T3 selection requires some knowledge of accessory work |
🎯 Who It’s For — Who It’s Not For
✅ Who it’s for
- Lifters who have completed 3–6 months of linear progression (Starting Strength, StrongLifts) and want more structure
- Beginners who want to train 4 days per week from the start
- Lifters who want both strength and hypertrophy from one programme
- Anyone who finds Starting Strength too simple or too low in volume
❌ Who it’s not for
- Complete beginners with no barbell experience — learn the movements first
- Lifters who can only train 2–3 days per week
- Advanced lifters — move to nSuns, Sheiko, or a competition peaking programme
🔄 GZCLP vs Starting Strength vs 5/3/1
| Programme | Level | Days/Week | Volume | Best For |
|---|---|---|---|---|
| GZCLP | Beginner–intermediate | 4 | Moderate–high | Bridge from linear to intermediate |
| Starting Strength | Beginner | 3 | Low | Absolute beginners |
| 5/3/1 | Intermediate | 4 | Low–moderate | Long-term strength, post-linear |
📚 The Research Behind the GZCL Method
- Multi-rep-range training: Schoenfeld (2010), Journal of Strength and Conditioning Research — training across multiple rep ranges (heavy, moderate, light) produces superior strength and hypertrophy adaptations compared to single-rep-range training.
- Volume and strength: Ralston et al. (2017), Journal of Strength and Conditioning Research — higher weekly training volume produces greater strength gains in intermediate lifters up to a recoverable threshold.
- Linear progression: Aaberg (2007), Resistance Training Instruction — linear progression (adding weight each session) is the most effective approach for novice and early-intermediate lifters due to rapid neural and structural adaptations.
FAQ
How long should I run GZCLP?
Until linear progression stalls on both T1 and T2 lifts — typically 3–6 months. Then transition to an intermediate programme like 5/3/1 or nSuns.
Can I run GZCLP 3 days a week?
Technically yes by rotating A/B/C/D across 3 days, but the programme is designed for 4 days. A 3-day schedule reduces frequency on each lift.
Do I need weightlifting shoes for GZCLP?
For squat days: recommended, especially for beginners with limited ankle mobility. Establishing good squat mechanics early with proper footwear pays dividends long-term.
What’s the difference between GZCL and GZCLP?
GZCL is the broader training method by Cody Lefever. GZCLP is a specific application of that method using linear progression — the most beginner-friendly version.
