Hevy Integrations: What Connects to What
"Does Hevy integrate with X" is one of the most common questions in strength tracking, and the honest answer is usually more interesting than yes or no. Most fitness apps don't integrate because of API asymmetry, not lack of interest. Here's the capability map.
The short answer
Hevy is one of the more open strength loggers. It publishes a developer API covering sets, reps, weights and dates, and it supports CSV export — which is why Hevy data can move into other tools at all. Almost everything fails on the other side: an integration needs both companies to expose a relevant endpoint, and most recovery wearables don't. Hevy + WHOOP is no exception — we covered that in detail separately.
How to read this guide
Two conventions, stated up front because they matter:
- We test capability, not products. Every claim below is a statement about an API surface or an export path as documented by the vendor. Where we cannot point to documentation, the cell says verify rather than guessing.
- Verify before relying on it. This area changes without notice. We publish the matrix as of October 2026, and the fastest way to check a specific cell is to look for the vendor's own documentation or the option in your app's settings.
The capability matrix
| Pairs with Hevy | Native two-way sync | Data path that works | Strength history moves? |
|---|---|---|---|
| WHOOP | No | Run in parallel; no shared dataset | Not without manual work |
| Strava | Verify | Check current sharing/export behaviour in-app | Depends on the path available |
| Apple Health | Not for strength detail | Activity, heart rate and duration only | Sets and reps are not surfaced |
| Google Health / Health Connect | Verify | Check current in-app behaviour | Depends on what is written |
| Garmin | Not documented | Manual — Hevy has no strength-logger bridge to Garmin training load | Export from Hevy, manual entry elsewhere |
| Fitbit / Fitbit Air | Not documented | Manual | Export from Hevy, manual entry elsewhere |
| Strong, FitNotes, LiftStrong | No | Manual re-log, or keep one logger only | Two systems, no merge |
| Your own tools (spreadsheet, API, AI assistant) | Yes — via API or CSV | Hevy developer API, or CSV export | Yes, fully |
The pattern is clear and it repeats across the whole category: the only row that works properly is the one where you control both ends. Everything else depends on a company that may or may not expose what you need.
Why integration is so rare
The reason is almost always API asymmetry, and understanding it means you can predict most answers without checking.
An integration needs a documented endpoint on both sides for the data you want to move. Hevy exposes one. Recovery wearables typically expose recovery, HRV, sleep and strain — because that's what they do — but not the per-set strength data a logger holds. There is no endpoint to write to and nothing to read.
That is the entire reason Hevy and WHOOP cannot connect. Neither company is being difficult: WHOOP's API simply doesn't surface WHOOP Strength Trainer data for an external partner to read. It is structural, which also means it won't be fixed by a product update.
The useful heuristic
Ask one question: does the other platform publish an API that includes the data you want? If no, there is no integration available regardless of what the marketing implies, and no amount of waiting will change it quickly. If yes, the integration is technically possible and is merely a matter of whether anyone has built it.
What you can actually do today
Given the matrix above, there are three workable arrangements. Which is right depends on what you want the data for.
1. Keep Hevy as the single source of truth, and use wearables alongside it
Log everything in Hevy once. Wear your recovery device for what it does well and decide how hard to train before the session, not after. This is the arrangement most lifters end up with, and it avoids the double-logging that makes multi-app setups unmaintainable. The cost is that the two datasets never join on a shared timeline.
2. Use Hevy's API or CSV export and build the join yourself
Because Hevy is open, your history is portable. Export the CSV, pull the wearable's own export, and join the two on date in a spreadsheet. This is manual and it is the only way to answer questions like whether your recovery state predicted your best sessions — a question no single app can currently answer, and one we look at in does WHOOP recovery predict your lift performance?
Four to six weeks of complete logs is enough to see a direction. For the arithmetic that turns those logs into a progression line, building an estimated 1RM trend is the method and the calculator does the work.
3. Drop the second app if it isn't earning its place
Worth saying plainly: many multi-app setups are a tax with no return. If you train two or three times a week and judge readiness reasonably from sleep and soreness, Hevy alone does the job better than Hevy plus a recovery band. The recovery wearable earns its subscription only if you will change sessions based on what it tells you.
Frequently asked
Does Hevy have a developer API?
Yes. Hevy publishes a developer API that exposes workout data including sets, reps, weights and dates. That makes Hevy one of the more open strength loggers, and it is the reason Hevy data can be moved into other tools at all.
Can I export my Hevy workouts to a spreadsheet?
Yes. Hevy supports CSV export from within the app, and the same data is available through its developer API. This is the most reliable way to get your Hevy history anywhere else.
Does Hevy integrate with WHOOP?
No. There is no native integration in either direction, and the obstacle is structural: WHOOP's public API does not expose per-set Strength Trainer data, so there is no endpoint for Hevy to build against. The two are used in parallel rather than synced.
Why do fitness apps not integrate with each other?
Almost always API asymmetry. One company exposes a documented API covering the relevant data while the other does not, so there is no endpoint for a partner to read or write. That is the same reason Hevy and WHOOP cannot connect, and it is structural rather than a missing feature.
Does Hevy sync to Apple Health or Google Health Connect?
Platform health stores are primarily activity, heart rate and duration focused rather than set-and-rep level, so they are not a general route for strength history. Verify the current state in your app's settings — this area changes often and vendors are not consistent about what they surface.
