Progression Charts

Access & Premium

Progression Charts are a premium feature. Free users see basic stats (calorie overview, workout activity, weight trend). Premium unlocks the full set of advanced charts described on this page.

Open them from the Statistics tab. Each chart has its own card and supports time-range selection — typically 1 month, 3 months, 6 months, and 1 year.

All charts are computed on-device from your training history. Nothing leaves your phone.

Strength Progress (Estimated 1RM)

Tracks your estimated one-rep max for each strength exercise over time. Even if you never actually do a 1-rep max, the app estimates one from your working sets so you can see whether your top-end strength is moving.

• Formula: Epley formula — weight × (1 + reps / 30) — applied to your heaviest set per session, then plotted over time
• Per exercise: open any exercise (Bench, Squat, Deadlift, etc.) to see its individual trend line
• What to look for: a slow upward slope means progressive overload is working; a flat line over 6+ weeks means it's time to deload, change rep range, or revisit recovery

Training Volume

Volume = sets × reps × weight. The app sums this across each session and plots the trend.

• By session: shows total volume per workout, useful for spotting fatigue weeks
• By week: shows weekly aggregate, the more useful view for spotting long-term trends
• By muscle group: filters volume to a specific muscle so you can see whether you're actually loading legs as much as you think you are

Volume is a leading indicator of strength gains — sustained increases over weeks usually precede 1RM gains by a month or two.

Personal Records

The PR view automatically detects three kinds of records and tags them in your history:

• Weight PR — the heaviest weight you've ever moved on this exercise, regardless of reps
• Reps PR — the most reps at a given weight
• Estimated 1RM PR — a new high on the calculated 1RM

PRs are flagged with a small badge in your workout history and listed chronologically on the PR chart so you can see how often you're setting new bests.

Muscle Balance

A spider chart showing how much volume you've put into each major muscle group over the selected time range. The chart has eight axes — chest, back, shoulders, arms, legs, glutes, core, and cardio — each scaled relative to a reasonable weekly target.

What it's good for:

• Spotting an obvious gap (a back that's half the size of chest? happens to almost everyone)
• Noticing whether your "leg day" is actually getting equal love to upper-body sessions
• Watching balance drift over time as your routine changes

The chart isn't prescriptive — there's no "perfect" shape. It's a tool for noticing imbalances you might want to address.

Workout Frequency Heatmap

A GitHub-style calendar grid showing every day of the past year, color-coded by training intensity:

• Empty — rest day
• Light — short or low-volume session
• Medium / Heavy — typical full session, scaling up to high-volume days

Useful for at-a-glance answers to questions like "did I actually train consistently in March?" and for spotting long gaps you might not remember taking.

Cardio

Cardio sessions get their own progression view tracking duration, distance (where applicable), and active calories. Each cardio modality (running, cycling, rowing, classes, etc.) charts independently so progress in one isn't washed out by another.
