Workouts (Apple)

Workouts (Apple) is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Workouts (Apple) rather than just read about it. In short: Workouts is a fitness companion and activity recording application developed by Apple Inc. for Apple Watch devices, used to start workout tracking and view metrics while an exercise activity is in progress. The app was first introduced alongside watchOS 1 on April 24, 2015, and is tightly integrated into the operating system's health tracking features.

Key takeaways

Workouts (Apple) belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Workouts (Apple) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Workouts (Apple) from memory before moving on to harder problems.

Reference excerpt

Workouts is a fitness companion and activity recording application developed by Apple Inc. for Apple Watch devices, used to start workout tracking and view metrics while an exercise activity is in progress. The app was first introduced alongside watchOS 1 on April 24, 2015, and is tightly integrated into the operating system's health tracking features. All workout history and deeper workout metrics can be viewed from within the Fitness and Health apps on a connected iPhone.

Overview The workouts app displays a list of activities and exercises for a user to begin recording, although the watch is also capable of detecting when a workout session begins on its own and notifying a user to start a workout. During a workout, the app will display the time elapsed since recording of the chosen activity began, the user's current heart rate, and the active and total kilojoules burned during the workout. Other metrics can vary depending on the type of activity, such as displaying the total altitude of a cycling workout or the total laps of a swimming program. Additional metrics may also be displayed by connecting the watch to bluetooth-enabled third-party exercise machines or accessories using the GymKit API. For water-based activities, the watch may ask for the length of the pool an activity is being conducted in, and will also set the device's water lock feature automatically once a workout has begun. During cycling activities, the workout can appear as a live activity on a connected iPhone, which can be used to display the workout metrics on a larger screen if the device is mounted to the bicycle. Since watchOS 9, swiping up on the metrics display will show a user's heart rate zones, which are five calculated segments which indicate the intensity of a workout based on their maximum heart rate. Workout views can also be customised to display a range of metrics in order to suit a user's needs and preferences. Workouts can be paused or segmented for breaks and changes in activity, and media controls can be accessed within the app itself during a workout. Workouts are displayed in different colours depending on the chosen goal - green for open activity, yellow for timed activities, blue for set distances, red for kilojoule targets, and purple for custom interval programs. The "Multisport" workout option allows users to switch between the indoor and outdoor versions of the swimming, cycling, and running activities in any order.

Types of workouts As of watchOS 10, the list of supported workout activities available for recording includes:*Indicates a water-based workout **Only available to wheelchair users

GymKit API GymKit is an integration API that was launched with watchOS 4.1 on 31 October 2017, which allows developers and manufacturers to enable bidirectional sync between the Apple Watch and certain cardio equipment. Once paired, compatible machines can display workout data and performance during workouts and send additional data to the Fitness app.

Worked examples

Example 1 — a first encounter with Workouts (Apple)

Start with the simplest possible case. Write down what Workouts (Apple) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Workouts (Apple) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Workouts (Apple) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Workouts (Apple)

In research: Workouts (Apple) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Workouts (Apple) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Workouts (Apple) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fitness apps, Health software, IOS-based software made by Apple Inc., so understanding it makes those chapters shorter.
In everyday life: Look for Workouts (Apple) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
