strength training equipment where the resistance means is a load that is an integral part of the device that can be varied by the user without adding or removing components to and from the equipment
Note 1 to entry: An example of equipment where this component is relevant is shown in Figure 1.
externally loaded equipment
strength training equipment where the main resistance means is a load that is not an integral part of the device which can be varied by the user by adding or removing components to and from the equipment
Note 1 to entry: Components to be added or removed are, for example, weight discs or bands.
permanent or adjustable constructive element creating a pre-set minimum stop position that provides the user with clearance to avoid entrapment without any further action of the user
rest or holder for a barbell or for a carriage on guided equipment (3.9), which needs to be engaged by the user, from which the user can begin the exercise motion or end at the completion of the exercise
component of strength training equipment that allows the user to activate resistance means for a specific exercise
Note 1 to entry: An example of equipment where this component is relevant is shown in Figure 2 a).
force or torque exerted by the user to perform the exercise
structure protruding from the frame of externally loaded equipment (3.2) for the purpose of holding weight either for a resistance means or for storage
Note 1 to entry: An example of equipment where this component is relevant is shown in Figure 2 b) and 2 c).AS ISO 20957.2 pdf download.
