What it is Filled
An exercise machine is a mechanical apparatus designed to support, guide or resist repeated bodily movement for physical training.
In scope
- Exercise modalities, supported movements, and the machine's intended training function
- Mechanisms that guide movement or generate resistance, assistance, or powered motion
- User interfaces, body supports, fit adjustments, and access requirements
- Operating modes, workload settings, feedback, and stopping behaviour
- Mechanical condition, installation constraints, protective features, and evidence governing use
Out of scope
- Loose free weights, resistance bands, and exercise mats without a machine mechanism
- Individual exercise prescriptions, diagnoses, and decisions about medical suitability
- Fitness facilities, membership services, and staff qualifications
- Product ranges, commercial offers, and procurement transactions
- General transport vehicles and industrial machines whose primary purpose is not exercise
- External training applications and personal activity records beyond their interfaces with the machine
Why it exists Filled
Enable an AI agent to recognise an exercise machine, record how it supports and loads bodily movement, judge its operating condition, and determine which uses or interventions are permitted.
Distinguishing features Filled
- Its intended function is bodily exercise; producing movement or requiring physical effort incidentally does not establish membership.
- A mechanical arrangement constrains movement, moves a contact surface, or transmits a controlled exercise load; a loose weight or passive mat alone does not meet this test.
- The exerciser interacts with designated supports or moving interfaces, such as pedals, handles, belts, seats, or levers.
- Membership does not require electricity: user-powered mechanisms and powered mechanisms can both qualify.
- An ordinary bicycle provides transport, while a stationary exercise cycle provides exercise through a stationary pedalling and loading arrangement.
What robots and AI may and may not do Filled
Must not
- Push a user to continue when they report pain, dizziness or chest symptoms.
- Operate or recommend a machine with a known fault, missing guard or frayed cable.
- Leave a running treadmill or loaded machine where children can reach it.
- Share a user's body or performance data without consent.
Only with a human decision
- Designing a programme for a person with a medical condition or recent injury.
May
- Guide a user on using an exercise machine within its settings and the user's stated limits.
- Log workouts and report machine faults to the operator.
- Remind users to adjust seats, pins and weights before starting.
Moral aspects Filled
- Exercise benefits health but overexertion can injure, especially for beginners and older people.
- Children are seriously hurt by home treadmills and weight stacks each year.
Who is affected
- Users
- Children in homes and gyms
- Gym staff
Owners Filled
Steward
The owner or operator of the gym or home where it is installed.
