Personal records and 1RM tracking in Boostcamp
PRs flagged the moment you hit them, plus per-exercise records, estimated 1RM and progress charts.
How does Boostcamp track personal records?
Boostcamp flags a personal record the moment you complete a set that beats your best, for top weight, set volume, estimated 1RM or a true 1RM. PR badges and the Lifetime and This Week boards are free. Boostcamp Pro adds each exercise's full Records and Charts, including your best performance at every rep count from 1 to 12.

How Boostcamp tracks your records
- 1
PRs are flagged during the workout
When a completed set beats your stored best for that exercise, a PR badge appears on the set. Unchecking the set removes it.
- 2
Every exercise keeps its own records
An exercise's Records tab lists your best set, actual and estimated 1RM (Brzycki), max volume and a Best Performance table for each rep count from 1 to 12, with dates. For cardio, it tracks max time, distance and best pace.
- 3
Charts show the trend
The Charts tab plots estimated and actual 1RM, total training volume, best set and max consecutive reps, daily, weekly or monthly.
- 4

What is an estimated 1RM?
An estimated one-rep max (e1RM) is a prediction of the heaviest weight you could lift for a single rep, calculated from a set of several reps with a lighter weight. It lets you track maximal strength without testing a true max, which is fatiguing and carries more risk than a normal working set.
The Brzycki formula is one of the most widely used estimates: 1RM = weight × 36 / (37 − reps). A set of 1 returns the weight itself, and each extra rep raises the estimate. The formula assumes the set was taken close to failure; a set stopped with several reps in reserve will underestimate your max.
Estimated 1RMs are most accurate at low reps and get less reliable as reps climb, because endurance, technique and fatigue start to matter as much as strength. Many coaches treat sets of roughly 1 to 6 reps as the most trustworthy inputs, and sets above about 10 to 12 reps as rough guides only.
Boostcamp calculates an estimated 1RM with the Brzycki formula for every logged set of 1 to 12 reps and flags a PR when the estimate beats your previous best.
Estimated 1RM from a 225 lb set at different rep counts
Brzycki formula: 1RM = weight × 36 / (37 − reps). Estimates are rounded to the nearest lb; the last column shows the set weight as a share of that estimate, which is (37 − reps) / 36.
| Set | Calculation | Estimated 1RM | Set as % of estimate |
|---|---|---|---|
| 225 lb × 1 | 225 × 36 / 36 | 225 lb | 100% |
| 225 lb × 3 | 225 × 36 / 34 | 238 lb | 94.4% |
| 225 lb × 5 | 225 × 36 / 32 | 253 lb | 88.9% |
| 225 lb × 8 | 225 × 36 / 29 | 279 lb | 80.6% |
| 225 lb × 10 | 225 × 36 / 27 | 300 lb | 75.0% |
Tips for using Personal records
- Compare like with like An estimated 1RM from a set of 3 and one from a set of 10 are not equally reliable. When you judge progress, compare estimates from similar rep ranges.
- Log every working set honestly PRs and estimates are only as good as the data behind them. Log the reps you actually completed, including missed reps, so your records reflect real performance.
- Use rep PRs, not just 1RM Beating your best 5-rep or 8-rep set is progress even when your top single hasn't moved. With Pro, the Best Performance table shows your best weight at every rep count from 1 to 12.
- Reset the baseline when conditions change After a long layoff, an injury or a switch to new equipment, set a new PR start date so new records reflect where you are now.
Which kinds of PR Boostcamp tracks
A personal record isn't only a heavier single. Boostcamp flags a PR for top weight, max set volume (weight × reps in one set), estimated 1RM and actual 1RM, so a set of 8 at a weight you've only done for 6 counts, and so does a set that moves more total weight than any before it. Non-weighted exercises track reps, time, distance and pace instead.
Estimated vs actual 1RM
Boostcamp keeps both numbers for each exercise. Actual 1RM is the heaviest single you've logged; estimated 1RM is calculated from your best set of 1 to 12 reps with the Brzycki formula. Many lifters rarely test a true single, so the estimated 1RM is usually the more up-to-date measure of strength, while the actual 1RM records what you've really lifted.
What lifters say
★★★★★“It makes me feel stronger and it gives me way more encouragement every time I log on and I see I’ve beat a PR, or just hitting a set better than the day before.”
★★★★★“when you make a PR it tells you, when you finish a workout it tells you. When you are consistent it tells you.”

Frequently asked questions
Yes. PR badges during workouts and the Lifetime and This Week PR boards are free. Each exercise's detailed Records and Charts tabs are part of Boostcamp Pro.
Exercise records use the Brzycki formula on your logged sets. With Pro, Exercise Analytics can also estimate 1RM from sets where you logged RPE.
Yes. Set a new PR start date for an exercise. PRs count from that date, and your workout history isn't deleted.
The Brzycki formula estimates a one-rep max as weight × 36 / (37 − reps). For example, 225 lb for 5 reps gives an estimated 1RM of about 253 lb.
An estimated 1RM is usually closest to your true max when it comes from a hard set of low reps. Estimates from sets above roughly 10 reps are less reliable, so treat them as a guide rather than a target.
No. Boostcamp's Brzycki estimate for records uses sets of 1 to 12 reps, because the formula becomes unreliable at higher rep counts. Warm-up sets don't count toward records.
