1. A fitness device, comprising:
an exercise assembly including a first rotary motor and a linear motor, wherein a user can apply an exerted force to operate the exercise assembly according to various movement trajectories of multiple training movements, such that the exercise assembly is driven by the linear motor to move linearly along an axis, and is driven by the first rotary motor to rotate;
wherein the first rotary motor outputs a rotational resistive force in response to the rotation of the exercise assembly, the linear motor outputs a linear resistive force in response to the movement of the exercise assembly, the rotational resistive force and the linear resistive force are combined to form an integrated resistive force, and the exerted force is greater than the integrated resistive force when the user operates the assembly.
