FormaGet FormaDouble progression: add reps, then add weight.
Double progression uses two variables in sequence. Build repetitions within a planned range, increase the load after the program’s completion rule is met, then begin again nearer the lower end.

A worked double-progression example
Suppose a program defines 3 sets of 8 to 10 repetitions at approximately 2 RIR. The rule is to increase load after all three sets reach 10 repetitions at the intended effort and execution standard.
| Session | Completed work | Decision |
|---|---|---|
| Week 1 | 70 lb: 8, 8, 8 at about 2 RIR | Keep the load and build repetitions. |
| Week 2 | 70 lb: 10, 9, 8 at about 2 RIR | The program rule is not met yet. |
| Week 3 | 70 lb: 10, 10, 10 at about 2 RIR | The rule is met under comparable conditions. |
| Week 4 | 75 lb: 8, 8, 8 at about 2 RIR | Load rises and repetitions reset within range. |
The range, number of sets, RIR target, and load increment are illustrative. They are not universal recommendations.
Why the method can be useful
It defines the next step
The lifter knows whether the current goal is another repetition or a load increase.
It works with fixed equipment
When the smallest available increment is large, repetition progression can bridge the gap.
It keeps performance visible
The log shows how the load increase was earned instead of recording only isolated PRs.
What must remain comparable
Exercise variation, equipment, range of motion, technique, rest, exercise order, and intended effort all affect interpretation. Reaching the top of a rep range by shortening range of motion or moving much closer to failure is not the same progression as reaching it under the original standard.
Define the completion rule before the session
A rule might use all work sets, a top set, or an average. The important part is consistency. Changing the rule after seeing the workout makes the trend harder to interpret.
What the research supports
Double progression is a practical programming convention, not a uniquely validated biological law. Its two ingredients have direct evidence. An eight-week randomized study in 43 resistance-trained adults compared increasing load with increasing repetitions and found both approaches viable. A ten-week within-subject trial in 39 previously untrained young adults also reported gains with both approaches and no between-protocol difference in the studied outcomes.
These studies do not establish one best repetition range, load increment, or completion rule for every exercise and lifter.
Frequently asked questions
What is double progression?
Double progression is a programming method that first increases repetitions within a chosen range, then increases load and returns repetitions toward the lower end of that range.
Does double progression require a specific rep range?
No. The range should fit the exercise, goal, equipment, and program. An 8 to 10 repetition example explains the method but is not a universal prescription.
Should I add weight after one set reaches the top of the range?
That depends on the rule defined by the program. Some plans require all target sets to reach the upper bound at the intended effort, while others use a top-set or average-performance rule.
Is double progression supported by research?
Trials have found that progressing repetitions and progressing load can both improve resistance-training outcomes over the studied periods. They do not prove that one double-progression template is universally optimal.
