The Good

  • Challenging For All Levels
  • Sturdy, Yet Comfortable
  • Dual-Purpose USB Port
  • Unique Features

The Bad

  • Occasional Static Electricity

Challenging For All Levels: With a 3.25 CPH motor, 15 incline levels and speeds up to 12 mph, the LifeSpan TR4000i provides a challenging workout for even the most hardcore runners.
Sturdy, Yet Comfortable: This model’s steel frame provides structural support to the 20-inch wide running surface, while eight compression shock absorbers across the deck reduce the impact on your back, knees and joints.
Dual-Purpose USB Port: A dual-purpose USB port allows you to upload your exercise data to LifeSpan’s online health-management program and charge all of your devices. Tracking your progress has never been easier. Coupled with its MP3 compatibility and built-in speakers, this unit has it all.
Unique Features: Intelli-Step keeps track of every step with remarkable accuracy, while the TR4000i’s Intelli-Guard suspends belt movement for 20 seconds if you need to step off the deck.
Occasional Static Electricity: Some people have had problems with static shock from this model. While this isn’t a deal breaker, it does provide a bit of an annoyance while exercising.
