Last Person Standing is a fitness elimination challenge. Each week you log heart-rate minutes toward a threshold. Hit it and you survive; miss it and you're eliminated. The threshold rises every week until one person is left standing.
Time your heart rate spends in Zone 2 or above during any activity — running, cycling, rowing, brisk hiking, anything your watch records with heart rate. Minutes are computed from your actual heart-rate samples, not the workout label. (In True Zone 2 challenges, only Zone 2 itself counts — see below.)
Zones are estimated from your age: max heart rate = 220 − age.
| Zone | Feels like | Heart rate (% of max) |
|---|---|---|
| 1 | Easy — warm-up, casual walking | below 60% |
| 2 | Steady — you can hold a conversation | 60–70% |
| 3 | Moderate — talking gets harder | 70–80% |
| 4 | Hard — short sentences only | 80–90% |
| 5 | Max effort — unsustainable | 90%+ |
Standard challenges count zones 2–5; True Zone 2 challenges count zone 2 only.
Some challenges score only minutes spent inside Zone 2 — time in zones 3–5 doesn't count. It rewards disciplined aerobic-base training: going harder doesn't help your score. The challenge page shows when a challenge uses True Zone 2; otherwise standard Zone 2+ scoring (zones 2–5) applies.
Any watch or tracker that syncs to Apple Health (iPhone) or Health Connect (Android) — Garmin, Fitbit, Samsung, Polar, Coros, Amazfit and others all feed those. Connect LPS to Apple Health or Health Connect in the app and your workouts sync automatically.
On Android, LPS reads workouts from Google Health Connect — your watch's own app has to write workouts into it. One-time setup:
Menu names shift between app versions — look for "Health Connect" in your app's settings or connected-services screen.
Strava on Android writes the workout but not the heart rate — its Health Connect permissions cover Exercise, Distance and Calories only, and there is no heart-rate setting to turn on. A workout recorded in Strava's Android or Galaxy Watch app reaches Health Connect with no heart-rate data, so LPS skips it as "no heart rate" and it scores nothing. Record with an app from the list above instead (Samsung Health on a Galaxy Watch, or Wahoo, Garmin, WHOOP, Polar), or add one of them as a second recorder. On iPhone this is different — see the Apple Health section below.
On iPhone, LPS reads workouts from Apple Health — whatever records your workout has to write them in there. Apple Watch does this automatically; other devices need a one-time toggle in their own app, allowing workouts and heart rate:
Strava on an Apple Watch has one more hop. The workout travels Strava on the watch → Strava on your iPhone → Apple Health → LPS, and each step has its own switch: the Strava sync toggle in the Watch app on your iPhone (open the Watch app, find Strava, turn its sync on — wording varies by version), Strava's Apple Health connection above, Strava's write permission under Settings → Health → Data Access & Devices → Strava, and LPS's read permission. Any one of them switching off stops everything after it, and the watch and Strava keep looking normal.
Menu names shift between app versions — look for "Apple Health" in your app's settings or connected-services screen. Then grant LPS read access when prompted (or check Settings → Health → Data Access & Devices → LPS).
Every challenge week is a 7-day window on the challenge's own weekly cycle (shown on the challenge page) — not necessarily Monday to Sunday. The week closes at midnight in the challenge's timezone at the end of its 7th day; results post about 12 hours later, around noon, so your watch data has time to sync. We send reminders 48 and 12 hours before the close, a sync nudge right when the week closes, and a results notification when they're in.
Each challenge starts at its initial threshold (say, 150 minutes) and rises by a fixed increment every week. Challenges begin with a warm-up period before Week 1 — no eliminations during warm-up, so you can get your syncing sorted.
When the week closes below the threshold, you're eliminated from that challenge. You can still see the leaderboard and cheer on the survivors — and join the next challenge.
Yes — corporate challenges support teams with team leaderboards alongside the individual game. See For companies for the free pilot and corporate options, or bring it to your own office.
Small challenges (SPARK) are free. Larger and corporate challenges are paid — see the pricing page for current tiers.
We store only computed zone minutes per workout — never your raw heart-rate stream, GPS routes, or other health records. Payments are handled by Stripe; we never see your card details.
Use the sync troubleshooter →It checks what LPS has received from you and walks you through the switches.
Work down this list — it's ordered by how often each one is the culprit:
Seeing the workout in Apple Health doesn't always mean the app that recorded it wrote it there — Strava and Garmin Connect need their own write permission turned on separately from your watch's own recording. Check Settings → Health → Data Access & Devices → the app you recorded with → Workouts and Heart Rate, not just LPS's read permission.
Workouts in Strava but not in Apple Health? That is the tell-tale for an Apple Watch + Strava setup: the data is stopping at Strava. Two switches can do this, and they can turn themselves off after an update — Strava's Apple Health connection (Strava → Settings → Apple Health) and the Strava sync toggle inside the Watch app on your iPhone. Turn both on; the missed workouts usually backfill on the next LPS sync.
On Android, Strava writes the workout to Health Connect but never the heart rate, and there is no permission to grant — a workout recorded in Strava lands as "skipped — no heart rate" and scores nothing. Record with Samsung Health, Garmin, Wahoo, WHOOP or Polar instead, or alongside.
