Progressive Overload
Progressive overload means doing more over time — more weight, more reps, or more sets. It's the fundamental driver of muscle growth and strength gains. HyperIron automates this so you don't have to plan it manually.
Two progression modes
When you create a program, you choose how each exercise progresses across the mesocycle:
Weight progression (default)
Weight progression uses double progression over your rep range: you add a rep each week at the same weight, and once you reach the top of the range the weight steps up one increment and the reps reset to what you can realistically do at the heavier load. That way a weight jump is about one rep harder — not the same reps at a heavier weight, which is a much bigger jump.
| Week | Weight | Reps | RIR | What changed |
|---|---|---|---|---|
| 1 | 170 lbs | 8 | 3 | start at the bottom of the range |
| 2 | 170 lbs | 9 | 3 | +1 rep |
| 3 | 170 lbs | 10 | 2 | +1 rep |
| 4 | 170 lbs | 11 | 2 | +1 rep |
| 5 | 170 lbs | 12 | 2 | top of the range |
| 6 | 175 lbs | 11 | 1 | weight steps up, reps reset to the equivalent |
Best for compound lifts (squat, bench, deadlift, rows) where small weight jumps are practical. (Exercises with a single rep target rather than a range use a small ~2%/week weight increase instead, since there's no range to climb.)
Rep progression
Weight stays fixed. Rep targets increase from the bottom to the top of your rep range.
| Week | Weight | Reps | RIR |
|---|---|---|---|
| 1 | 30 lbs | 8 | 3 |
| 2 | 30 lbs | 9 | 3 |
| 3 | 30 lbs | 10 | 2 |
| 4 | 30 lbs | 10 | 2 |
| 5 | 30 lbs | 11 | 2 |
| 6 | 30 lbs | 12 | 1 |
Once you hit the top of the range, increase weight in the next mesocycle and start over. Best for isolation exercises and movements where weight jumps are large relative to the load (e.g., going from 30 lb to 35 lb dumbbells is a 17% jump).
:::note Automatic fallback If your program is set to weight progression but an exercise can't actually increase weight — bodyweight movements, or small weights with large increments — HyperIron automatically progresses reps for that exercise instead. You don't need to manage this per exercise. :::
Starting weight
Your working weight is derived from your logged sets — the best set of your most recent session anchors the plan, and the progression rule projects forward from there. Exercises you've trained in a previous program start anchored from that history; a brand-new exercise just shows its rep range and RIR target, and you find the weight in the gym on your first session.
All weights are rounded to your configured increment (e.g., 5 lbs for barbells, 2.5 lbs for dumbbells). There is nothing to set or correct — if a suggestion is off, lift what's right and log it; the next session anchors on what you did.
The RIR ramp
Both modes use the same intensity ramp — your RIR target decreases across the mesocycle:
| Phase | Portion of mesocycle | RIR | Feel |
|---|---|---|---|
| Conservative | First ~1/3 | 3 | Comfortable — several reps left |
| Moderate | Middle ~1/2 | 2 | Working hard — a couple more possible |
| Aggressive | Final ~1/6 (at least 1 week) | 1 (or 0) | Near failure |
The early weeks feel easy by design. They let you establish movement patterns before intensity peaks.
You can set the minimum RIR to 0 for exercises where training to failure is appropriate (typically isolations). The default of 1 is safer for compound lifts.
Volume auto-regulation
The third axis of progression — volume (sets per exercise) — is driven by your feedback. After each session, you rate your fatigue, and HyperIron adjusts your set count for the following week. See Fatigue & Autoregulation for details.
Deload weeks
A mesocycle can optionally end with a deload week:
- Weight drops to a percentage of your current working weight (default: the full working weight with reduced reps and sets)
- Volume drops to ~2 sets per exercise
- Reps are roughly halved
- Effort is easy — nowhere near failure
Some lifters prefer planned deloads every 4–6 weeks; others deload reactively when needed. Both approaches work — you choose when creating your program.
How it all fits together
HyperIron balances three forces simultaneously:
- Load progression — Weight or reps go up on a schedule
- Intensity ramp — RIR decreases, pushing closer to failure
- Autoregulated volume — Sets adjust based on real recovery
This pushes hard enough to drive adaptation while self-correcting when you're under-recovering or have room for more work. Follow the targets, rate your fatigue honestly, and the system handles the math.
