Life Fitness F3 Overview

Most people shy away from folding treadmills because they are wary that they may not be as sturdy or durable as their non-folding counterparts. The Life Fitness F3 is one of the best foldable treadmills we’ve come across, truly a rare breed. It has high quality engineering and amazing electronics. Above all, the FlexDeck shock absorption is something that also sets itself apart from other foldable treadmills at this price point.

The Life Fitness is truly high quality, they didn’t skimp on a single quality when building this foldable treadmill. It also includes a 5 year warranty, which should instill confidence as most foldable treadmills have much shorter warranties.


The F3’s crowning achievement is its FlexDeck cushioning, which is also available on the F1. In addition, the F3 has up to 20% power incline, and which is one of the widest incline options in the Life Fitness lineup. The F3 is also energy smart! If the machine is plugged in but not in use, it automatically reduces its power draw. The motor also adjusts to the users weight, so it won’t work harder than it has to. If there’s any drawback to the F3, it’s that it shares the same deck size as the F1, which is too small for users with a wide gait.

  • 55” x 20” running deck
  • FlexDeck cushioning shock absorption system
  • 20% power incline capabilities, which is the highest of the Life Fitness line
  • Easily foldable for storage and travel
