Taking out your phone between sets is a small hassle that adds up. Unlock, open the app, put it down again — and logging starts to feel like a chore. With an Apple Watch, a glance at your wrist shows your next target, and one tap logs the set. Here are some tips for logging strength training with Apple Watch.
Why log from your wrist
- Fewer interruptions between sets: no phone to take out, so your rest rhythm stays intact.
- Fewer missed records: you log right after the set instead of trying to remember it later.
- Heart rate and calories are captured automatically: Apple Watch tracks them during the workout.
Tip 1: Set targets in advance and log with one tap
Entering numbers on a small screen over and over is tiring. Instead, put per-exercise targets (weight, reps, sets) into your menu ahead of time. The Watch's logging screen then opens with the target values pre-filled, so a set that went to plan takes a single tap on "Log." You only adjust the numbers when something differed.
Tip 2: Fine-tune with the Digital Crown
To change a value, turn the Digital Crown rather than tapping +/− buttons. Select either the weight or reps field first, then turn the Crown. Your finger doesn't cover the screen, so you can watch the number as you adjust. Weight changes by the exercise's "weight increment" setting — if your machine moves in 2.5kg steps, set it to 2.5kg and each notch of the Crown matches a real plate change.
Tip 3: Leave the detailed input for the iPhone
Things like RPE and notes don't suit a small screen. Keep the Watch to weight and reps, and add RPE and notes later from the iPhone's record-editing screen after your workout. Treating the Watch as "the minimum now, the details later" makes logging easier to keep up.
Tip 4: Time cardio with the stopwatch
For running, cycling, and other cardio, open the exercise, tap "Start," and tap "End" when you're done. The duration is saved in seconds, along with heart rate and calories. Timing continues even if your wrist drops and the screen turns off.
Tip 5: Treat heart rate and calories as a guide
Apple Watch's calorie figure is an estimate based on heart rate and wrist motion. Compared with continuous movement like running, strength training tends to be estimated less accurately. It's useful for gauging whether today felt harder than last week, but it's best not to treat it as a precise number.
Using the iPhone and Watch together
You can finish a whole workout on the Watch alone, or join a workout you started on the iPhone partway through. For example: check the menu on the iPhone, log on the Watch inside the gym, then review on the iPhone afterward. Whichever device you log from, it all comes together as one workout.
