Program design is where anatomy and exercise science become an actual service you can sell. This lesson gives you the rep-range framework, the periodization basics, and the exercise-selection logic behind every program you'll ever write.
A program is not a list of exercises. It's a deliberate structure that applies the right stimulus, in the right amount, at the right time, to move a specific client toward a specific goal. Get this right and clients see consistent progress and stay with you for years. Get it wrong — usually through random variety with no progression — and clients plateau and leave.
Rep Ranges by Goal
The single most useful table you'll reference when writing programs:
| Goal | Intensity (% of 1RM) | Rep Range | Rest Between Sets |
|---|---|---|---|
| Maximal Strength | 85-100% | 1-5 reps | 2-5 minutes |
| Hypertrophy (muscle growth) | 65-85% | 6-12 reps | 60-90 seconds |
| Muscular Endurance | 50-65% | 12-20+ reps | 30-60 seconds |
| Power | 30-60% (moved explosively) | 1-5 reps | 2-5 minutes |
In practice, most client programs blend these ranges across a week rather than picking just one — a strength-focused main lift, hypertrophy-range accessory work, and some higher-rep finishing work is a common, effective structure.
Periodization Basics
Periodization is the planned variation of training over time, rather than repeating the same program indefinitely. Two approaches cover the vast majority of client programming:
- Linear periodization: volume starts high and intensity low, then gradually flips — higher intensity, lower volume — over weeks. Simple, effective, ideal for beginner and intermediate clients.
- Undulating periodization: intensity and volume vary within the same week (e.g. a heavy day, a moderate day, a light/high-rep day). More complex, often used with more advanced clients or to fight boredom.
For most new trainers, starting with simple linear periodization in 4-6 week blocks — then reassessing and adjusting — is more than enough to produce excellent client results.
Exercise Selection & Session Structure
Using the six movement patterns from Lesson 3, a well-structured session typically follows this shape:
| Session Segment | Purpose | Example |
|---|---|---|
| Warm-up (5-8 min) | Raise temperature, prep the specific patterns used today | Light cardio + dynamic mobility for today's main lift |
| Primary lift | The main strength stimulus, usually a compound movement | Squat, deadlift, bench, or overhead press variation |
| Accessory work | Support the primary lift and address weak points | Rows, lunges, single-leg work matching today's pattern |
| Core / conditioning | Round out the session, address stability or cardio goals | Anti-rotation core work, short finisher |
| Cool-down (3-5 min) | Lower heart rate, begin recovery | Static stretching, breathing |
Pick a goal, experience level, and training days to generate a sample weekly structure — a starting point to adapt, not a finished program.
This is a structural starting point — always adjust based on the client's actual assessment (Lesson 5), movement quality, and progress over time.

Common Program Design Mistakes
Program design is a skill you'll keep refining for years, but the framework in this lesson — rep ranges by goal, simple periodization, and structured sessions built from movement patterns — is enough to write genuinely effective programs from day one. Lesson 5 covers how to gather the information that makes a program actually fit the person in front of you.
- Rep ranges vary by goal: 1-5 for strength, 6-12 for hypertrophy, 12-20+ for endurance, with rest periods scaling accordingly.
- Linear periodization (progressing intensity up, volume down over weeks) is simple and effective for most beginner and intermediate clients.
- Sessions should follow a consistent structure: warm-up, primary lift, accessory work, core/conditioning, cool-down.
- The most common new-trainer mistake is too much variety and not enough progression — repeat key lifts across weeks to actually build strength.
- Use the Program Design Builder above for two different goals and compare the structures.
- Download the program design template and fill out one full week for a hypothetical client.
- Identify which movement pattern (from Lesson 3) is missing from a workout you've done recently.
