A conservative next step
This calculator demonstrates double progression. Keep the load while repetitions move toward the top of a range. Once the top is completed, add the chosen increment and return to a lower repetition target.
Use completed work, not the plan
Enter what you actually completed with acceptable technique. If the session was interrupted or the target was missed, repeating it can be more useful than forcing an increase.
Keep manual control
Equipment, recovery, pain, and coaching direction can change the sensible target. The calculation is informational and never changes training data.
