Motor, deck & running area
The motor and deck decide how a treadmill feels and how long it lasts under daily commercial load.
Motor (CHP)
Look for continuous horsepower (CHP), not peak. Commercial treadmills typically need 3.5–5.0 CHP for sustained use.
Deck & cushioning
A thick, well-cushioned deck protects members' joints and the machine's lifespan under heavy daily footfall.
Running area
A longer, wider belt (55cm+ wide, 150cm+ long) suits taller users and running gaits.
