This is a vertical pedal stair stepper (often marketed as a "stair climber" for home use). It is a hybrid between a traditional pedal stepper and a vertical climber, designed specifically for home environments.
Here are the specific characteristics of this model:
1. Mechanical Design
A-Frame Construction: The triangular "A" shape provides stability while allowing the machine to be foldable. This makes it ideal for apartments or small spaces where it can be tucked under a bed or in a closet.
Independent Hydraulic Resistance: Most of these models use two hydraulic cylinders (visible under the pedals) to provide resistance.
Manual Power: This is a non-electric machine. The pace and intensity are entirely dictated by your own movement, meaning it doesn't need to be plugged in.
