Getting started
How it works
- 01
Choose a program
Pick P90X or Insanity and the day you're starting on. You can start partway through a program.
- 02
Do your workouts
Follow each move on a Garmin watch, or log your sets on the web or your phone. Switchback fills in the reps and weights from last time.
- 03
Track your progress
Every workout, rep, and completed day shows up in your history and calendar.
On the watch
What a Garmin watch shows during a workout.
- MOVE BY MOVE
- Each move on its own screen, in the workout's order — reps, weighted reps, and timed holds.
- LAST TIME'S NUMBERS
- The reps and weight you did last time, filled in when each move starts.
- GARMIN ACTIVITY
- Records heart rate, calories, and training effect, and appears in Garmin Connect like any other activity.
- NO PHONE NEEDED
- Once your program is on the watch, workouts run without a phone nearby.
- BUTTON CONTROLS
- Runs on the buttons of round Garmin watches — no touchscreen needed.
Garmin watches
Works with Garmin watches.
Switchback runs on round, five-button Garmin watches, with support expanding to more models over time. No Garmin watch? You can still track every workout on the web and your phone.
Web and phone
Track your progress and history.
See every workout you've logged, with the reps and weight for each move. A calendar shows the whole program: the days you've done, your rest days, and the day you're on.
Why this exists
Following a program like P90X used to mean a paper worksheet, or a phone I had to check between sets — and none of it counted as a real workout on my Garmin. Switchback keeps your numbers and records a proper Garmin activity.
Pricing

FAQ
Questions and answers.
Do I need a Garmin watch?
No. You can track your workouts on the web or your phone. A Garmin watch adds move-by-move guidance and records the session as a Garmin activity.
Do I need my phone during a workout?
No. Once your program is on the watch, workouts run without a phone. Your logs sync afterward when your phone reconnects.
Is this an official P90X or Insanity app?
No. Switchback is independent and is not affiliated with, sponsored by, or endorsed by Beachbody or BODi. P90X® and INSANITY® are trademarks of Beachbody, LLC / BODi. Switchback tracks a program you already own; it does not include the workout videos or any other Beachbody/BODi content.
Which watches does it work with?
Round, five-button Garmin watches, with more models added over time.
What happens after the free trial?
Your history stays. Guided watch workouts and full tracking pause until you subscribe; nothing you logged is deleted.
