Double progression: add reps first, then weight

Double progression: keep the weight and add reps until your sets reach the top of the range at your target effort, then add one weight step and start over.

Double progression means you keep the same weight and add reps until your working sets reach the top of your rep range at the effort you planned, then add one small weight step and drop back to the bottom of the range. Reps first, weight second, repeat. It answers the question "add a rep every set" leaves open: what happens when the reps stop coming.

What is double progression?

Pick a rep range, say 8 to 12, and a target effort, say 2 reps in reserve (you stop each set with about two good reps left). Keep the weight until your working sets average the top of that range at that effort. Then add one weight step and start again at the bottom of the range. Two things progress, reps and load, which is where the name comes from.

The American College of Sports Medicine describes the same idea: once you can do one or two reps more than your target at a given load, add 2 to 10% to the weight (ACSM, 2009).

One more rep is progress. It still isn't a plan.

An extra rep at the same weight counts as overload. In an 8-week trial, trained lifters who kept the load and added reps grew their quads about as much as lifters who added load (Plotkin et al., 2022). We cover that study in more reps or more weight.

But "add a rep every set, every week" has no exit. Reps at one weight can't climb forever, and without a rule for what happens at the top, you either stall or start guessing. Double progression is that rule.

Do all your sets need the same weight?

For most lifts, yes. Keep one working weight across your sets. Reps often slip a little from the first set to the last, and that is normal. Judge the session on the average across your working sets. Once that average reaches the top of the range at your target effort, you've earned more weight.

Using the average is a coaching choice. It keeps one great first set from rushing you up, and one tired last set from holding you back. It's the rule Orion Coach uses for intermediate and advanced lifters.

Getting the effort part right

Double progression only works if "the top of the range" is reached at a consistent effort. Reps in reserve is the usual way to pin that down. In experienced squatters, rated RIR tracked bar speed closely (r = 0.88, inverse), less so in novices (r = 0.77) (Zourdos et al., 2016). Helms and colleagues suggest newer lifters practice logging RIR before relying on it fully (Helms et al., 2016).

Coach Orion's call

Each lift in your program has a rep range and a target effort, usually 2 reps in reserve. After a session, I average the reps you logged across your working sets and the reps in reserve you reported. If that average sits inside the range and your effort was on target, or at most a rep harder, every set asks for one more rep next time at the same weight. When your average reaches the top of the range, I add one weight step and send you back to the bottom.

One step is 5 lb per hand on dumbbells, 5 lb on a barbell (2.5 lb if you own microplates, and only weights your plates can make), and 10 lb on a pulley. A bigger surplus never earns a bigger jump. If your sets came in more than a rep harder than I asked, or you went to failure, I drop one step. Falling short of the range at the right effort is a hold, not a drop.

Inside a session I make the same one-step calls set to set, and I usually hold the weight going into your last set. At your heaviest dumbbell I add reps instead, up to 3 past the top of the range, then move you to a harder exercise (the dumbbell ceiling). Beginners get one rep target instead of a range. The full rule is on how Orion progresses you.

What it looks like on one lift

Worked example: a walkthrough of how Orion applies this rule, not a real user's data.

• Dumbbell flat bench press, 8 to 12 reps, target 2 reps in reserve, 40 lb dumbbells.
• Session 1: every working set lands at 10 reps at about 2 in reserve. Average 10. Next session asks for 11 at 40 lb.
• Session 2: sets land at 11. Next session asks for 12.
• Session 3: sets average 12 at the target effort. That's the top of the range.
• Session 4: 45 lb dumbbells, back to 8 reps, and the climb starts again.
• If session 3 had come in at failure instead, the weight would drop one step to 35 lb rather than going up.

What the evidence doesn't tell us

No trial compares averaging reps across sets with other ways of deciding when to add weight. The fixed 5 lb step is a practical choice for home equipment; ACSM frames the jump as a percentage. And reps in reserve is a self-rating, so its accuracy depends on practice.
