There are two entirely separate noise problems and almost all advice conflates them, which is why so much of it does not work.

Problem 1: airborne noise

The motor hum, the belt whir, the fan. It travels through the air, reflects off hard surfaces, and goes under doors. It is the noise you hear.

Solutions: a closed door, soft furnishings in the room, a quieter machine. Straightforward, and rarely the actual complaint.

Problem 2: structure-borne noise

Your footstrike impact travels into the deck, through the frame, into the floor joists, and radiates out of your neighbor's ceiling as a low thud. It is the noise they hear, and it is almost entirely unrelated to how quiet the machine is.

This is what generates complaints. A whisper-quiet treadmill motor changes nothing about it.

The isolation stack, from the floor up

The floor. Nothing you can change, but position matters — see below.
A high-density closed-cell foam layer. Half an inch to an inch, gym-mat grade. This is the compliant layer that decouples.
A dense rubber mat on top. Heavy, not thick. Weight is what absorbs energy; a thin foam 'treadmill mat' does far less.
The machine, leveled properly on its feet.

That stack costs well under $150 and is the single most effective intervention available. A rubber mat alone helps; rubber over foam helps considerably more, because you need both mass and compliance.

Placement matters as much as isolation

Over a load-bearing wall or a structural beam, never in the middle of a floor span. The middle of a span is a drum skin; the edge is not.
In a corner, which is stiffer than the middle of any surface.
On the ground floor if there is any choice at all.
Not against a shared wall, which couples airborne noise directly into the neighbouring unit.

Behavior beats hardware

Walk rather than run. The single biggest reduction available, and it is free.
Use the machine between about 9am and 8pm. Most noise complaints are about timing, not volume.
Talk to your neighbor first. A two-minute conversation prevents most complaints entirely.
Keep sessions to a reasonable length. An hour of thumping is harder to tolerate than twenty minutes.

What to buy if noise is the binding constraint

Machine	Floor noise	Verdict for an apartment
Magnetic exercise bike	Essentially none	The right answer
Recumbent bike	Essentially none	The right answer
Manual walking belt	Very low, no motor	Good, if you can live with the gait
Walking pad at walking speed	Low on a mat	Workable
Treadmill, walking	Moderate	Workable on a proper stack
Treadmill, running	High	Expect complaints
Air bike	Low impact, very high airborne	No

Frequently asked questions

How do I stop my treadmill disturbing downstairs neighbors?

Build an isolation stack — high-density foam with a dense rubber mat on top — position the machine over a load-bearing wall rather than the middle of a floor span, and walk rather than run. Walking instead of running is the single biggest reduction available and it is free.

Do treadmill mats actually reduce noise?

Yes, substantially, and they are the highest-value purchase alongside the machine. A dense rubber mat decouples the frame from the floor and absorbs impact energy. Thin foam mats sold as treadmill mats do far less — look for mass and density rather than thickness alone.

What is the quietest cardio machine for an apartment?

A magnetic exercise bike, by a wide margin. There is no impact loading at all and the resistance mechanism touches nothing. A recumbent is equally quiet. Among treadmills, a walking pad used at walking speed on a proper mat is about as quiet as the category gets.

Can I use a treadmill on an upper floor?

Structurally, in almost any modern building, yes — the load is well within residential floor ratings. The constraints are the lease, the neighbors, and the fact that upper floors flex more, which increases transmitted impact. Position over a load-bearing wall and use proper isolation.

Is a walking pad quiet enough for an apartment?

At walking speed on a dense rubber mat, generally yes. The motor is small and quiet, and walking transmits far less impact than running. It is the most practical treadmill-type machine for a shared building.
