Our Rating

Rating: 94.3/100. The TRM 425 is a luxury treadmill in Precor’s Precision Series, a collection featuring commercial quality treadmills for home use. These treadmills have the same components as Precor treadmills you might use at a health club, but they have lower prices and longer warranties for home environments. (The parts are under warranty for ten years.) The impressive TRM 425 is ideal for power walking and jogging to help you drop weight quickly, tone your lower body and support good heart health.

One highlight of this Precor is its automated ramp, which gives you an incline range of -2% to +15% for extra calorie burn and muscle sculpting. Whatever incline level you choose, shock absorbers support your comfort and help you train for longer time periods; the cushioning is advanced with extra firmness provided at your point of push-off. Combined with Precor’s special stride technology, it noticeably reduces the stress of cardio training on your joints compared with outdoor exercise. Another perk of this treadmill is the programming, which supports two user IDs and has nine preset workouts.
