Chest press weight stacks by brand: Technogym vs Life Fitness vs Hammer Strength

What a stack weight tells you, and what it does not

A stack weight is the total of the plates in the stack. It tells you the heaviest setting, not the force at the handles: pulleys, cams and lever arms sit between the pin and your hands, and every brand builds them differently. So the same pin number on two brands is not the same press.

Converting a load between two chest presses needs a force curve for both machines, measured with a force gauge or estimated from a mechanical model. None of the chest presses below has one yet, so the comparator answers "No data yet" for every pair. We prefer that to a guess.

How every figure is labelled

MachineConvert never invents a number. Each figure carries one of three levels, with its source link and the date it was read:

Measured

Read on the machine itself with a force gauge, following the measurement protocol, with a proof (continuous video or photos) and the date.

Manufacturer

Quoted word for word from the manufacturer's official page or document, in the units printed there, with the link and the date it was read. A stack weight says what the plates weigh, not what you feel at the handle.

Estimated

Computed from a mechanical model of the machine (lever, cam or pulley) built from sourced inputs. Each estimate shows its method, its error band and a derivation page, and is marked as not verified by measurement.

MethodologyData rules

Help fill the gaps

If you have access to one of these machines and a force gauge, a measurement is the fastest way to turn "No data yet" into a real comparison. Every submission is reviewed before it is published.
