A mechanical engineer's guide to evaluating home treadmills: continuous horsepower (CHP), deck suspension, roller diameters, and subscription traps.
Buying a home treadmill is fraught with marketing gimmicks. Manufacturers advertise inflated "Peak Horsepower" and dazzling touchscreens while cutting corners on motor continuous duty ratings, roller sizes, and frame welds.
Continuous Horsepower (CHP) vs. Peak HP
Always inspect the Continuous Duty Horsepower (CHP) rating, not Peak HP. A continuous rating indicates the power the motor can sustain under continuous load without overheating. For serious runners, demand at least 3.0 CHP. For walking or light jogging, 2.5 CHP is acceptable.
