Every great powerlifter eventually writes their own programme. Not because existing programmes are bad — but because understanding why a programme works is what separates lifters who keep progressing from those who endlessly programme-hop. This guide teaches you the principles behind every programme in the Castiron Lift library, so you can build one that fits your schedule, your weak points, and your goals. This is the final article in the Castiron Lift Programming Series.

🎯 The Core Principles of Programme Design
Every effective powerlifting programme — from Starting Strength to Sheiko to the Castiron Lift Strength Programme — is built on the same foundational principles:
| Principle | What It Means | How to Apply It |
|---|---|---|
| Progressive Overload | Training stress must increase over time to drive adaptation | Add weight, reps, or sets systematically |
| Specificity | Train the movements you want to improve | Squat, bench, deadlift must be the core of any powerlifting programme |
| Variation | The body adapts to repeated stimuli — variation prevents accommodation | Rotate rep ranges, exercises, or intensities over time |
| Recovery | Adaptation happens during recovery, not during training | Plan deloads, manage volume, prioritise sleep and nutrition |
| Individualisation | No programme works equally for everyone | Adjust volume, frequency, and exercise selection to your recovery capacity |
🗓️ Step 1 — Choose Your Training Frequency
The Castiron Lift 6-step programme builder — follow each step to design your custom programme
| Days/week available | Recommended structure | Example |
|---|---|---|
| 3 days | Full body each session | Castiron Lift Beginner/Strength Programme, 5/3/1 |
| 4 days | Upper/lower split or 4-day full body | Conjugate (ME Lower/DE Upper/ME Upper/DE Lower) |
| 5–6 days | High frequency — each lift 3x/week | nSuns, Sheiko |
Research guidance: Colquhoun et al. (2018) in the Journal of Strength and Conditioning Research found that training frequency of 3x/week per lift produced greater strength gains than 1x/week when volume was equated. Higher frequency is generally better — up to recovery capacity.
🏋️ Step 2 — Select Your Main Lifts
For powerlifting, the main lifts are non-negotiable: squat, bench press, and deadlift. The overhead press is the most common fourth lift for upper body development. Every session should include at least one of these as the primary movement.
| Lift | Primary muscles | Competition lift? | Frequency recommendation |
|---|---|---|---|
| Squat | Quads, glutes, hamstrings | ✅ Yes | 2–3x/week |
| Bench Press | Chest, front delts, triceps | ✅ Yes | 2–3x/week |
| Deadlift | Hamstrings, glutes, back | ✅ Yes | 1–2x/week |
| Overhead Press | Delts, triceps, upper traps | ❌ No (but valuable) | 1–2x/week |
🔄 Step 3 — Choose Your Periodisation Model
| Model | How it works | Best for | Castiron Lift guide |
|---|---|---|---|
| Linear (LP) | Add weight every session or week | Beginners | Beginner Programme |
| Daily Undulating (DUP) | Vary rep ranges within the week | Intermediates | Strength Programme |
| Block Periodisation | Hypertrophy → Strength → Peaking blocks | Intermediate–advanced | Sheiko Guide |
| Concurrent (Conjugate) | ME and DE days simultaneously | Advanced/equipped | Conjugate Guide |
📊 Step 4 — Set Your Volume and Intensity
Volume (sets x reps) and intensity (%1RM) are the two primary training variables. Research from Schoenfeld et al. (2017) in the Journal of Strength and Conditioning Research established that 10–20 sets per muscle group per week is the effective range for hypertrophy, while Zatsiorsky & Kraemer (2020) in Science and Practice of Strength Training documented that strength development requires intensities above 80% 1RM.
| Goal | Rep range | Intensity | Sets per lift per week |
|---|---|---|---|
| Strength | 1–6 | 80–100% | 10–20 |
| Hypertrophy | 6–12 | 65–80% | 10–20 |
| Power/Speed | 1–3 | 50–70% (max speed) or 85–95% | 6–15 |
| Endurance/GPP | 12–20+ | 50–65% | As needed |
🔧 Step 5 — Add Accessory Work
Accessories address weak points and build the supporting musculature that drives the main lifts. The rule: accessories serve the main lifts, not the other way around.
| Weak point | Likely cause | Recommended accessories |
|---|---|---|
| Squat — failing at bottom | Quad weakness | Leg press, hack squat, front squat |
| Squat — failing at top | Glute/hip weakness | Hip thrust, Romanian deadlift, good morning |
| Bench — failing off chest | Chest/front delt weakness | Dumbbell press, incline press, cable fly |
| Bench — failing at lockout | Tricep weakness | Close-grip bench, JM press, tricep pushdowns |
| Deadlift — failing off floor | Quad/back weakness | Deficit deadlift, leg press, Romanian deadlift |
| Deadlift — failing at lockout | Glute/hip weakness | Hip thrust, rack pull, glute-ham raise |
💤 Step 6 — Plan Your Deloads
Every custom programme needs a deload strategy. The fitness-fatigue model (Zatsiorsky & Kraemer, 2020) shows that fatigue masks fitness — deloads allow fatigue to dissipate and true strength gains to emerge.
| Training level | Deload frequency | Deload structure |
|---|---|---|
| Beginner | Every 8–12 weeks or when stalling | Reduce volume 40–60%, keep intensity |
| Intermediate | Every 4–6 weeks | Reduce both volume and intensity 40–60% |
| Advanced | Every 3–4 weeks | Full deload — volume and intensity both reduced significantly |
See our complete Deload Week Guide — USA for full deload protocols.
📝 Step 7 — Build Your Template
Combine all six steps into a weekly template. Here’s an example custom 3-day intermediate programme built using this framework:
| EXAMPLE CUSTOM 3-DAY INTERMEDIATE PROGRAMME | ||||
|---|---|---|---|---|
| Day | Main Lift 1 | Main Lift 2 | Main Lift 3 | Accessories |
| Monday (Strength) | Squat 4x4–6 @ 82% | Bench 4x4–6 @ 82% | Deadlift 3x4–6 @ 82% | Lat pulldown, face pulls |
| Wednesday (Hypertrophy) | Squat 4x8–12 @ 68% | OHP 4x8–12 @ 68% | RDL 3x8–12 @ 68% | Dumbbell rows, leg press |
| Friday (Power) | Squat 5x2–3 @ 88% | Bench 5x2–3 @ 88% | Deadlift 4x2–3 @ 88% | Ab work, glute-ham raises |
This is essentially the Castiron Lift Strength Programme — which is what happens when you apply these principles correctly.
⚠️ Common Programme Design Mistakes
- Too much volume too soon: Start conservative. You can always add volume — you can’t undo overtraining.
- No progression plan: A programme without a clear progression rule is just a workout. Define exactly how and when you add weight.
- Ignoring weak points: Most lifters programme their strengths and avoid their weaknesses. Identify your sticking points and address them directly.
- No deload plan: Every programme needs a deload strategy built in from day one.
- Changing the programme too soon: Give any programme at least 8–12 weeks before evaluating. Most lifters abandon programmes before they work.
- Copying advanced programmes as a beginner: Sheiko and Conjugate are not beginner programmes. Match the programme to your training age.
👟 Footwear Consistency in Custom Programmes
One often-overlooked element of programme design: footwear consistency. Whatever shoes you train in, use them consistently across all sessions of the same lift. Switching footwear mid-programme disrupts the motor patterns you’ve built. For custom programmes with multiple squat sessions per week, use the same weightlifting shoes every session. See our Best Squat Shoes 2026 — USA guide for recommendations.

FAQ
How long should my programme be?
8–16 weeks is the standard range. Shorter programmes (8 weeks) suit peaking and testing. Longer programmes (12–16 weeks) suit base-building and hypertrophy phases.
How do I know if my programme is working?
Track your lifts every session. If your working weights are increasing over 4–8 weeks, the programme is working. If they’re stagnant or declining, adjust volume, intensity, or recovery.
Should I write my own programme or use an existing one?
Use an existing programme first. The Castiron Lift Beginner and Strength Programmes are free and built on the same principles in this guide. Write your own once you understand why those programmes work.
