Diagnose first
Separate impact, vibration, and mechanical sound.
A dropped dumbbell, a rocking machine, a clicking selector, and a spoken workout are different noise problems. Impact and vibration can travel through the floor-ceiling assembly and through connected building elements rather than staying inside the room.
National Research Council Canada research distinguishes direct transmission through a floor-ceiling assembly from flanking transmission through connected paths. That is why a product or surface can behave differently in two rooms and why a single mat cannot establish apartment suitability.

Largest lever
Change the event before changing the floor.
Set loads down under control, avoid dropped repetitions, choose step-based or cycle conditioning instead of repeated jumping when the building is sensitive, and use exercise variations that do not require explosive floor contact. These choices reduce the source event rather than asking a thin surface to contain it.
The current lower-noise setup uses adjustable dumbbells, bands, and an indoor bike because they can support controlled sessions. This is a planning judgment, not a measured claim that those products are inaudible.

At the station
Remove rocking, contact, and avoidable clatter.
Place equipment on a stable, level surface; keep it from touching walls or loose furniture; tighten and maintain it according to the manufacturer; and organize selectors or accessories so they are not dropped between sets. Test at the time of day the room will actually be used.
The IC4 product page lists 100 levels of magnetic resistance. That specification describes the resistance system, not a sound rating. It cannot support a promise that pedaling, adjustment, rider movement, or floor transmission will be silent.

Floor boundary
Use a mat for its stated job, not as a soundproofing claim.
The standard Manduka PRO is listed as a 6 millimeter closed-cell exercise mat. It can define a floor station and separate the body from a hard surface, but its manufacturer page does not establish impact-insulation performance for weights or machines.
NRC guidance notes that floor toppings do not produce the same impact-sound improvement on every floor type. If meaningful vibration control or impact flooring is required, the whole floor, ceiling, topping, equipment, and transmission path need appropriate evaluation.

Boundary
Let the building set the final rule.
A lease, quiet-hours policy, neighbor response, or structural concern can make an otherwise useful setup inappropriate. The absence of a complaint during one test also does not prove that every session, load, or time of day will be acceptable.
For persistent transmission, heavy equipment, structural loading, or a requirement for soundproofing, consult the landlord, building manager, engineer, or acoustics professional. Workout Authority should never convert a lower-noise plan into a guarantee.
