True Fitness has four categories of home treadmills. The series names are M, ES, PS and Z. All have heavy-gauge steel frames that are robotically welded, so there’s no need for owners to occasionally tighten the bolts. Horsepower is strong, ranging from 3.0 to 4.0. Their top speed is 12 mph. Except for the M Series, all have incline or incline/decline to replicate outdoor surface conditions and better promote muscle toning.
All of the True treadmills frames have lifelong guarantees, and the more expensive treadmills have 10 years of parts protection plus 30 years of motor protection.
