This Star Trac treadmill is a solid machine that will give you hours and hours of heart-pumping cardio workouts.
Reviewers rate the E-TR off the charts for performance, reliability, and comfort, so the only question to ask is, do you really need a commercial treadmill (designed to be used 16 hours a day) for your home gym?
Companies like Landice, Life Fitness, and Precor offer better warranties, but this E-Series beast has the biggest motor of them all. There’s really no downside to it, just don’t pay too much: we’ve seen the Star Trac E-TR treadmill selling online for as high as $6,699 and as low as $4,995 so shop around with that price disparity in mind.
