Buying guides and spec explainers
Treadmill spec sheets are written to be skimmed favourably. These guides explain what each number means and which ones you can safely ignore.
Almost every confusing treadmill specification is confusing on purpose. Peak horsepower is a larger number than continuous-duty horsepower and describes a condition the motor cannot sustain. Incline is quoted as a percentage because 15% sounds steeper than its true 8.5 degrees. Deck length is quoted in inches of belt, not inches of usable stride.
The explainers here take one specification at a time and answer three questions about it: what the number actually measures, what value you need given your height, weight and pace, and what goes wrong if you buy under it. Where a figure can be checked at home with a tape measure, the guide says how.
The broader buying guides sit above the explainers and put them in order — what to settle first, what to compare second, and what to leave until you are choosing between two specific machines.
