Does BulkForged work on a Garmin Forerunner?

On most of them. BulkForged's free watch app runs on the Forerunner 70, 165, 170, 245, 255, 265, 570, 745, 945, 955, 965 and 970. Music and S versions run it too. It runs a whole gym workout from your wrist, with your phone left in the locker.

Which Forerunner watches does BulkForged run on?

Screen sizes are in pixels, from Garmin's Connect IQ developer files. BulkForged draws each line in the largest type that fits. So the 218-pixel 255S shows the same set overview as the 970, in smaller type.

Which Forerunners does it not run on?

• The Forerunner 45 and 55.
• The Forerunner 645, 645 Music and 935.
• Older models, such as the 230, 235, 630, 735XT and 920XT.

Not sure which one you have? Garmin's Connect IQ store lists every compatible watch on the app's page. See every supported model.

Does it work on a Forerunner without a touchscreen?

Yes. The 245, 255, 745 and 945 have buttons only, and BulkForged needs nothing else.

• START confirms and moves on: it begins a set, moves from weight to reps, logs the set, and skips the rest timer.
• UP and DOWN change the weight or reps.
• BACK steps back. From the set overview it opens the workout menu, where you can jump to another exercise.

On a Forerunner with a touchscreen, a swipe up or down also changes a number.

Is anything different on the Forerunner 245?

One thing. The 245 keeps the workout on the watch. It sends it to your phone once, when you finish.

On every other Forerunner, the 245 Music included, your phone shows the workout live while you train. The watch can also join a workout you started on the phone.

How is it different from the Forerunner's own Strength activity?

Garmin's Strength activity counts your reps from your wrist. After each set, you fix the count and add the weight. Where it lives depends on the model:

• Forerunner 965: press START and choose Strength. The first time, it asks which wrist the watch is on.
• Forerunner 970: press START, then choose Activities, Gym and Strength.

The 965's manual also warns, "Leg exercises may not be counted." We read both manuals on 7 October 2026.

BulkForged starts from your plan instead:

• Before each set, it shows the exercise, the weight and the reps to aim for.
• You confirm the weight, then the reps you did.
• The rest timer starts on its own and buzzes when it ends.
• The workout runs offline and uploads when the watch has a connection.

How do I set it up on a Forerunner?

1. Install BulkForged on your Android phone from Google Play, and the free watch app from Garmin's Connect IQ store.
2. In the phone app, open Settings, then Account & watch, then Add your watch, and tap Generate pairing code. Pairing needs a BulkForged account.
3. On the watch, open BulkForged and choose Pair watch. Press UP or DOWN to set each digit of the code, and START to move to the next one.
4. Start a routine from the watch.

Does the workout show up in Garmin Connect?

Yes. A workout you run on the watch also saves to Garmin Connect as a strength training activity, with heart rate and calories. Your sets and weights stay in BulkForged. More in what's saved where.

What does it cost?

The watch app is free, and so is BulkForged's Basic plan: every workout, your history, your routines and your records. Coaching, which sets your next targets for you and shows why each one moved, is a paid plan after a 14-day preview. See what each plan includes.

Is there an iPhone app?

Not yet. BulkForged is Android only today. iPhone is coming soon. Join the waitlist.
