Double progression is a loading rule with two dials. You work inside a rep range, say 8 to 12; you add reps until every set reaches the top of the range; then you add load and drop back to the bottom. Reps move first, weight second.
Double progression answers the question "when do I go heavier?" with a rule instead of a feeling: when all your sets hit the top of the range. Until then the job is one more rep than last time at the same weight. The rep range is the buffer that lets a fixed dumbbell jump, which can be large, arrive only when you have earned it.
It is the quiet default for most accessory work in a coached program, and the rule a member can run alone on a homework day.
Four weeks on a single-arm row
Three sets of a single-arm dumbbell row, range 8 to 12, starting with a dumbbell that gives twelve clean reps on set one and fewer on the later sets.
| Week | Reps per set | Decision |
|---|---|---|
| 1 | 12 · 10 · 8 | Same weight next week |
| 2 | 12 · 11 · 9 | Same weight; the third set is the one to chase |
| 3 | 12 · 12 · 11 | One rep short; same weight once more |
| 4 | 12 · 12 · 12 | Go up one dumbbell; expect roughly 9 · 8 · 8 |
Week five starts near the bottom of the range with the heavier dumbbell and the cycle repeats. Nothing was guessed. Every decision came from the record of the previous week, which is why the loads get written down.
The confusion: double versus linear progression
Linear progression adds load every session with reps fixed. Double progression adds load only when the reps say so, which might be every week or every fourth week. Both are progressive overload; they differ in what triggers the jump.
Linear suits barbell lifts, where small plates allow small jumps and a beginner's legs can absorb them. Double suits dumbbell and upper-body work, where the next weight up is a big step and the muscles are smaller, and beginners on any movement still being learned, because extra reps at a stable weight are practice as well as progress. Choosing the starting dumbbell is its own small skill, covered at how to pick a dumbbell weight.
Where it shows up in a Coresa session
Most of the second half of a small group session runs on it: rows, presses, split squats, curls, carries measured in metres rather than reps. The coach's cue is usually "same weight, one more than last time." Because each person's loads are recorded, the coach knows who hit twelve on every set and whose dumbbell moves up, and eight people can be on eight different weeks of the same rule at once.
Common questions
What if I stall at the same reps for three weeks?
Narrow the range (10 to 12 instead of 8 to 12) so the jump arrives sooner, or make a smaller jump if the equipment allows. A three-week stall on an accessory is usually sleep or effort before it is programming.
How wide should the rep range be?
Four or five reps is typical: 6 to 10 for heavier work, 8 to 12 for most accessories, 12 to 15 for small muscles. Wider ranges hide stalls; narrower ones force jumps you may not be ready for.
Can I use double progression on a plank or a carry?
Yes, with seconds or metres in place of reps. Hold a range, say 30 to 45 seconds; when every set reaches 45, add load or a harder variation and drop back to 30.
