Continuous horsepower (chp) is the power of the treadmills during regular usage. Horsepower (hp) indicates peak power, but treadmills, which are used continuously over time, are better served by describing continuous horsepower. The two are not equal: if you see the same number next to both acronyms, the continuous horsepower is more powerful because it’s describing power over time instead of just peak power. Runners should seek out more power, around 3.0 continuous horsepower, while walkers will be satisfied with around 2.0 continuous horsepower.
