Start a Workout Directly From Your Watch

Open the Workout app on your Apple Watch by pressing the Digital Crown (the button on the side) and swiping to find it, or ask Siri "start a workout." The app shows a list of workout types: Running, Walking, Cycling, Swimming, Elliptical, Rowing Machine, Stair Stepper, and others depending on your watch model. Tap the one you're about to do.

Once you tap a workout type, the watch shows your current heart rate and a three-second countdown before it starts recording. You'll see real-time data on the screen — distance, time, calories, and heart rate — as you move. When you finish, press the red stop button, then choose "End" to save the workout or "Discard" if you want to delete it.

The watch records your workout automatically and stores it in the Health app on your iPhone. You don't need to do anything else — it syncs on its own when your watch is near your phone.

Key Takeaways

  • Press the Digital Crown on your watch, find the Workout app, and tap the activity type you're about to do — the watch starts counting down and begins recording when ready.
  • Your watch displays distance, time, calories burned, and heart rate in real time while you exercise.
  • When you finish, press the red stop button and tap "End" to save the workout to your Health app.
  • Workouts sync automatically to your iPhone's Health app without any extra steps from you.
  • You can also start a workout by asking Siri "start a [workout type]" without opening the app.

What Happens If Your Watch Model Doesn't Have Your Activity

Older Apple Watch models (Series 3 and earlier) have fewer built-in workout types than newer ones. If you don't see your specific activity — say, rock climbing or pickleball — use the closest match. Running works for sprinting, Walking covers hiking, and Cycling covers stationary bikes.

If you want to track an activity that doesn't fit any preset type, choose "Other" at the bottom of the workout list. Your watch will still record time, distance (if you have GPS), and heart rate, though it won't calculate calories as accurately as it would for a named activity.

Using Your iPhone to Start a Workout

You can also start a workout from your iPhone's Workout app instead of using the watch itself. Open the Workout app on your iPhone, tap the activity type, and tap "Start." Your watch will vibrate and show the countdown, and it begins recording on both devices at once.

This method is useful if you're setting up a workout before you leave the house or if you prefer the larger screen to select your activity. The watch still does all the recording — your phone is just a remote control to start it.

Pausing and Resuming a Workout

While a workout is running, swipe left on the watch screen to see the pause button (a double vertical line). Tap it to pause. Your watch stops the timer but keeps the workout open — you can resume by tapping the play button, or end it by tapping the stop button.

Pausing is useful if you stop for water, traffic, or a rest. The watch doesn't count paused time toward your workout, so your pace and calorie burn stay accurate to the time you were actually moving.

Viewing Your Workout History

After you save a workout, it appears in the Workout app on your watch under "Recent." Tap any workout to see details: total time, distance, calories, average heart rate, and elevation gain if you were outdoors. You can also see all your workouts in the Health app on your iPhone by opening it, tapping the "Browse" tab, and selecting "Workouts."

Your iPhone's Health app shows more detail than the watch screen, including a map of your route (if you had GPS on), splits by mile or kilometer, and how your performance compares to previous workouts of the same type. This is where you'll see trends over weeks and months.

Customizing Workout Settings Before You Start

Before you tap "Start" on a workout, you can set a goal. Tap the three dots (or swipe down, depending on your watch model) to choose between Open (no goal), Calories, Time, or Distance. If you pick Distance, you set how far you want to go; if you pick Time, you set how long you want to exercise.

When you reach your goal, your watch vibrates and alerts you. You can keep going after that — the goal doesn't stop the workout, it just marks a milestone. This is helpful if you're training for a specific distance or trying to hit a daily time target.

Troubleshooting: Workout Won't Start or Save

If the Workout app won't open, restart your watch by holding the side button until you see the power-off slider, then slide to power off. Wait 10 seconds and hold the side button again until the Apple logo appears. This fixes most app freezes.

If a workout won't save after you tap "End," check that your watch has enough storage. Go to Settings on your watch, tap General, then About, and look at Available space. If it's very low (under 500 MB), delete old workouts or photos from your watch to free up room. If the problem continues, unpair your watch from your iPhone (Settings > Bluetooth > your watch > Forget This Device) and pair it again.

Frequently Asked Questions

Do I need my phone with me to record a workout?

No. Your Apple Watch records workouts on its own using its built-in GPS (on GPS or GPS + Cellular models) and heart rate sensor. Your phone doesn't need to be nearby. The workout syncs to your phone later when they're in range of each other.

Can I edit a workout after I save it?

You can't change the distance, time, or calories in the Workout app itself. However, you can delete a workout and record it again, or use the Health app on your iPhone to manually add a workout if you forgot to record one. Open Health, tap the Browse tab, select Workouts, tap the plus sign, and enter the details.

Why does my watch show different calorie counts than my phone?

Your watch calculates calories based on your heart rate, age, weight, and the activity type. If you updated your personal information on your iPhone but not on your watch, the numbers may differ. Go to the Watch app on your iPhone, tap Health, and make sure your weight and age match what's in the Health app.

What's the difference between "Other" and a named workout type?

Named workouts (Running, Cycling, Swimming) use activity-specific formulas to calculate calories and pace. "Other" records time and heart rate but estimates calories less accurately because the watch doesn't know what you're doing. Use a named workout whenever your activity matches one.

Can I see my workouts on my Mac or iPad?

Yes. Open the Health app on any Apple device signed into your iCloud account, and your workouts appear in the Workouts section. Your data syncs across all your devices automatically through iCloud.
