After 12 weeks of double progression
135 → 145 lb
Estimated 1RM 171 → 189 lb · target rep range 8–12
Week by week
Hit every set in the range, then the weight goes up and reps reset to the bottom. Repeat.
| Week | Target | What to do |

Get Kovo freeHow double progression works
Progressive overload is simple to say and easy to get wrong. The mistake is adding weight every session until your form falls apart and you stall. Double progression fixes that with two levers instead of one:
- Reps first. Keep the weight the same and add one rep per set each week until you hit the top of your rep range on every set.
- Then weight. Once you top the range, add the smallest increment your gym allows and drop back to the bottom of the range. Climb again.
You always progress something, but you only add load once you've genuinely earned it. That's why it outlasts add-weight-every-day programs that burn out in a month.
How to actually use this
Pick the smallest jump
The weekly jump is the single biggest mistake. Use the smallest plates you have. 5 lb on a press feels like nothing and adds up to 60+ lb a year if you keep earning it. Big jumps stall you.
Progress is not a straight line
The table is the plan, not a promise. Some weeks you won't get the reps. Stay at that weight and try again. If you stall three weeks running, take a lighter week and restart from there.
Run it per lift
Big compounds (squat, deadlift) tolerate slightly bigger jumps than small isolations (curls, lateral raises). Run the calculator once per main lift with the right increment for each.
FAQ
What is progressive overload?
Progressive overload is the rule that muscles only adapt when you ask more of them over time. In practice that means gradually doing more: more weight, more reps, or more quality sets than you did before. Without it, you can train hard forever and stay exactly the same.
What's the best way to apply progressive overload?
For most lifters, double progression. Pick a rep range (say 8 to 12). Stay at a weight until you can hit the top of the range for every set, then add the smallest weight increment and drop back to the bottom of the range. It's safer and more sustainable than adding weight every session, and it's what this calculator plans for you.
How fast should I add weight?
Slower than you want to. The smallest jump the gym lets you make is usually right: about 5 lb (2.5 kg) on upper-body lifts and 5 to 10 lb (2.5 to 5 kg) on lower-body lifts, and only once you've earned it by hitting the top of your rep range across all sets. Beginners can move faster; experienced lifters move in smaller, slower steps.
What if I can't get the reps one week?
Stay at the same weight and rep target and try again next session. Progress is not linear. If you stall at the same spot for three or more weeks, take a lighter week (a deload) and then resume. Forcing weight on before you've earned it is how form breaks down and progress stalls.
Does progressive overload work for beginners?
Yes, and it works fastest for beginners because untrained muscle adapts quickly. Newer lifters can often add weight every week or two rather than waiting to top out a rep range. The double-progression plan here still works; you'll just move through it faster.
How is this different from the Kovo app?
This page gives you a fixed projection from one set. The Kovo app runs progressive overload adaptively: it reads every set you actually log, the weight, the reps, and how hard it felt, and adjusts next week's targets for you. It also builds the whole program and handles the rest of your training. This calculator is the manual version of one piece of that.
