Progression and periodisation
The six routes to progressive overload, how to build a mesocycle, when to deload, and what to do when you stall.
Progressive overload does not mean “add weight every week”. It means the stimulus increases in some measurable way over time. When the weight stops going up — and it stops sooner than you think — there are five other routes.
The six routes to progression
| Route | How to apply it | When to use it |
|---|---|---|
| Load | +2.5 kg or one machine step | Beginners and main lifts; runs out sooner than you expect |
| Reps | Same load, one more rep per set | The main route for intermediates |
| Sets | Add one weekly set to the target muscle | When recovery allows it |
| Density | Same work with less rest | Conditioning phases or short on time |
| Range or control | More range, less bounce, cleaner tempo | When technique was the limiter |
| Proximity to failure | From 3 RIR to 1 RIR across the block | The classic mesocycle structure |
Double progression: the default method
Set a range (say 8–12). Work with a weight until you hit 12 reps on every set; then add weight and go back to 8. It is simple, it is measurable and it works for years.
Building a mesocycle
- 1
Pick a length: 4–6 weeks
Long enough to accumulate progress, short enough to correct course if the plan is not working.
- 2
Week 1: entry
Target volume minus 1–2 sets per muscle, effort at 3 RIR. This is where you calibrate loads.
- 3
Weeks 2–4: accumulation
Add reps or sets and move progressively closer to failure (3 → 2 → 1 RIR).
- 4
Week 5: deload
Half the sets, loads at 60–70%, well away from failure. You come back with less fatigue and usually hit new numbers.
- 5
Repeat, changing little
Keep the main lifts, rotate the accessories. Comparing blocks only makes sense if something stays the same.
A deload does not cost gains and it clears out fatigue
A supervised trial with a one-week deload found the deload group maintained (and on some measures improved) size and squat performance. The practice is widespread in strength sports: in one survey the typical deload lasts ~6.4 days and is applied every ~5.6 weeks. The evidence is still limited, but the cost of deloading is low.
Periodisation: linear, undulating or none
Periodising beats not periodising; the specific model matters little
The meta-analysis by Harries and colleagues found no differences between linear and undulating periodisation for upper or lower body strength. What the reviews do show is that planning progression beats training without structure.
- Linear: volume drops and intensity rises across the weeks. Simple, good for peaking for a number.
- Undulating: rep ranges alternate within the week (heavy / medium / light). Useful for managing joint fatigue.
- Block: phases with a dominant goal (volume accumulation, then intensification). For advanced lifters with a calendar.
Plateaus: diagnose before you change
| Symptom | Likely cause | Adjustment |
|---|---|---|
| Weight is not going up, and neither are reps | Not enough volume or too little effort | Add 2 weekly sets or get closer to failure |
| Performance drops across the board | Accumulated fatigue, sleep or a calorie deficit | Deload for a week and review recovery |
| You progress on machines but not on the main lift | Technique or specificity | More frequency on the movement with moderate loads |
| You progress then crash every 3 weeks | Progression is too aggressive | Smaller jumps, more often |
| Growing joint discomfort | Exercise choice or load | Change the resistance profile and cut load temporarily |
Before you change the program
Check for two weeks: sleep, protein and calorie intake, and whether you are genuinely logging effort. Most “plateaus” are recovery problems dressed up as programming problems.
Takeaways
- Double progression as the default method; weight is not the only route.
- Blocks of 4–6 weeks with a deload at the end.
- Periodise, yes; obsess over the model, no.
- Diagnose the plateau before rebuilding the whole plan.
