Overview
A leg exerciser from Under, model TY59, weighing 7.51 kilograms with magnetic resistance rated to a 15 kilogram max setting, finished in black.
The magnetic resistance system sets it apart from simpler friction-pedal exercisers, typically giving smoother, quieter adjustment across resistance levels. At 7.51 kg it is heavier and presumably sturdier than lighter pedal exercisers, trading portability for stability.

Who it's for
Suits users wanting adjustable, quiet resistance for seated leg exercise, such as rehab or desk-based movement, who do not need to carry it around often. Less suited to anyone wanting the lightest, most portable option, since this weighs meaningfully more than basic pedal exercisers.
