Workout Features
More Accurate Workout Data
Thanks to the improvements made to heart rate measurement hardware and GPS hardware as well as optimizations to algorithms, the accuracy of heart rate measurements and GPS positioning for professional workouts has increased greatly. For example, the accuracy of heart rate measurements has reached 5 bpm during workouts such as interval running and marathon events, the accurate route positioning is able to locate a single running track, and the real-time pace accuracy and distance accuracy have reached industry-leading levels.
Workout Modes
The watch supports GNSS positioning and provides multiple professional workout modes, such as running, cycling, swimming, triathlon, mountain hiking, and trail running. A variety of workout modes are available for your customization. You can add your desired workout modes to or remove unwanted ones from the list of frequently used modes.
Professional Running Data
The watch can record a variety of professional workout data, such as duration, distance covered, calories burnt, cadence, stride, heart rate zone, aerobic training stress, anaerobic training stress, VO2Max, and recovery time, to make exercising more scientific. Huawei’s science-based fitness system provides evaluations and suggestions for entry-level runners.
Multiple Heart Rate Zones
The maximum heart rate varies depending on the workout mode. Maximum heart rates can be set using different labels to accurately calculate calories burnt in a certain workout mode.
Heart Rate Zones and Pace Zones
Five levels of workout intensity are defined using the heart rate zones and pace zones, corresponding to five states of energy consumption.
Physical Status
After Outdoor run mode is enabled for a period of time, the watch calculates and informs you of your current physical status, so that you can adjust your workout strategy in a timely manner to avoid injuries.
Heart Rate Recovery
It’s the difference between your peak heart rate during exercise and your heart rate soon after you stop. The speed and degree of heart rate recovery after exercise can be used to measure adaptability to a training load and physical fitness.
Resting Heart Rate
The resting heart rate refers to the stable heart rate measured when a person is awake and relaxed. Long-term regular exercise can enhance heart functions and lower the resting heart rate.
RAI — Huawei’s Brand-New Running Capability Evaluation System
Running ability index (RAI) uses running records to evaluate the runner’s running performance, quantify their capability, and determine their level. For example, after the runner completes a race or training session, the index helps rank (grade) them among all runners, so that they can get a better understanding of how well they are doing and whether they are making progress. Real-time RAI represents your current status, which is the level of running capability after you’ve finished running that day (so it will fluctuate). Recent RAI is calculated based on your recent real-time RAIs and evaluates your recent running status. This brand-new running capability evaluation system uses an upgrade algorithm to calculate the RAI based on the relationship between the heart rate and pace after each training session, even if the runner does not push themselves to their limit. This keeps you informed of your running status.
Training Status
Training Load
Training load equals training time multiplied by training intensity, and is an accurate reflection of the training amount and the impact of training on the body.
VO2Max
VO2Max indicates the highest level of oxygen uptake and utilization per kilogram of body weight per time unit during a long period of intense exercise. It reflects the body’s ability to intake, transport, and utilize oxygen, and is therefore an important indicator for assessing the ability to do aerobic exercise.
Training Performance
Aerobic training stress indicates the benefits of aerobic exercise for the body during a single workout. Long-term aerobic training can effectively improve this index. Anaerobic training stress indicates the benefits of high-intensity training for the body during a single workout. High-intensity interval training can effectively improve this index.
AI Running Plan
The watch supports more personalized, user-friendly, scientific, and professional smart running plans customized based on your training goals and times. Such a training plan automatically adjusts the training content and the difficulty level of subsequent courses based on your completion status, training status, and feedback, and provides summaries to help you reach your goals more quickly, on a weekly basis.
Personalized training plan
Differentiated training plans are developed based on information such as runners’ personal information, running goals, and running capabilities, allowing personalized and more effective training.
Intelligent adjustment of training content
With the help of the smart running plan algorithm, the watch intelligently adjusts the course schedule for the next week and pays attention to the runner’s status at all times. This algorithm combines the weekly training records and user feedback, removing unnecessary choices and preventing the plans from being rigid and difficult to follow.
Data-based guidance
Based on professional theories such as Daniels Running Formula, the watch provides suitable guidance on running methods, workout intensity, and workout load. Plans can be managed through the phone app and then pushed to the watch for easier use. The watch reminds you of your heart rate zone and pace zone in real time, providing precise guidance and preventing you from exercising incorrectly.
Real-time guidance from the watch
The training content is pushed to the watch. When your motion switch and intensity exceed a certain range, you’ll receive voice and card notifications.
Gradual capability improvement
The principle of scientific training is followed to gradually increase the training volume and improve training.
Periodic training
Based on the classic running training system, running involves several phases, including the preliminary, improvement, consolidation, and reduction phases, which are effective at helping improve the performance of runners.
Strength training for runners
Training plans may include suitable strength training to lay a foundation for improving performance.
Daily running plans for ordinary users
Daily scientific plans are developed for ordinary users to maintain and improve their physical fitness.
Advanced plans for runners
Advanced plans are developed to better prepare runners for a race, by helping them controlling their training pace (such as arranging pre-race training reduction) on the basis of targeted training.
Auto-detect Workouts
The watch identifies and reminds you to start the workout mode corresponding to your current workout status. You can either ignore the reminder or touch it to enter the corresponding workout mode. Currently, this feature is only available for Indoor run, Outdoor run, Indoor walk, Outdoor walk, Elliptical, and Rower.
Workout Route Sharing
You can import other users’ workout routes and export yours to share with others via the Huawei Health app.
Route Back
If you get lost in an outdoor adventure, all you need to do is enable the route back and real-time voice guidance features, and then you’ll be guided back. When you get lost in environments such as deserts and hills, switch to straight line navigation to quickly return to where you came from. The watch calculates the navigation distance and displays the remaining distance and estimated arrival time.
Activity Rings
The accelerometer and gyroscope are used to identify and monitor your diversified exercise status throughout the day. The number of steps, calories burnt, activity intensity, and number of standing times can be collected and displayed. It is encouraged to complete the activity rings on a daily basis by setting reasonable goals and smart reminders as well as incentives, thus cultivating exercising habits. This will also help build product loyalty.
