Short answer
If you want to enter your own sets and compare past sessions, consider Strong or Hevy; if you prefer adaptive exercise suggestions, examine Fitbod; if you want an iPhone-first log with clear targets to attempt next time, LIFT is another option when it becomes publicly available.
None of these apps guarantees that you will add weight every workout, and LIFT has not yet launched publicly on the App Store.
What should progressive overload look like in a real workout?
Imagine someone can bench press 60 kg for 8 clean repetitions. They keep a similar movement, range of motion and effort on the next sessions and try a modest improvement only when it is appropriate.
| Session | What the log says | Reasonable next step |
|---|---|---|
| Week 1 | 60 kg × 8 reps | Record this as your starting point. |
| Week 2 | 60 kg × 9 reps | One more clean rep at the same weight is progress. |
| Week 3 | 60 kg × 10 reps | If you have reached your intended rep range, consider a small load increase next time. |
| Week 4 | 62.5 kg × 8 reps | Compare effort, technique and the longer trend. |
This is often called double progression: add reps within a target range first, then increase weight while returning to the lower part of that range. Actual progress varies, and fatigue or illness may call for maintaining or reducing the load.
Compare workout-tracking approaches
| App | Progression approach | Availability and limits |
|---|---|---|
| LIFT | Logs sets, reps and weight; shows previous performances and offers a target to attempt when an exercise repeats. | iPhone prelaunch; public pricing not announced; not a nutrition or sleep tracker. |
| Hevy | Tracks lifts and history; Hevy's current product documentation describes Trainer progression recommendations. | Already available; check the plan and feature details directly. |
| Strong | Set and rep logs and training history help you set your own next targets. | Already available on iPhone and Android. |
| Fitbod | Adapts suggested weights, reps and training from logged performance. | Already available; adaptation is not a guaranteed result. |

Five things to test in a progressive overload tracker
- Can you see last time's result before your next set? Knowing your previous weight and reps is more useful than chasing an abstract app score.
- Can you record real exercise performance? Count working sets, repetitions, load and ideally the conditions that affect comparability.
- Can it show a trend? One set is noisy; several similar workouts are more informative.
- Does it treat suggested targets as suggestions? Soreness, technique and recovery may mean staying at or below the previous load.
- Does it fit your device and routine? A simple log you actually use can be better than an elaborate tool you avoid.
Is more weight always better for building muscle?
No; adding weight is one way to increase the challenge, but reps, set quality, range of motion and total weekly work also matter. The 2026 American College of Sports Medicine evidence review found resistance training builds muscle and that higher training volumes are associated with greater hypertrophy. It does not mean that any app causes growth or that one training variable should rise indefinitely.
Read how to think about weekly sets and how to build muscle for the larger context.
Which app is the better fit for LIFT's target user?
LIFT is positioned for lifters who already care about logging their work, repeating training plans and attempting a clear next goal without having to design a full spreadsheet. That is a statement about product design, not proven superiority over Hevy, Strong or Fitbod.
