The Treadmill Motor is what turns the belt as you run. We recommend at least 2 HP (Horsepower) motors, 2.5+ HP for jogging, and 3.0+ HP for running.

Treadmill Deck dimensions are measured in inches: Width x Length. The wider and longer the deck, the safer it is (55-60 inches long recommended for running).

The Treadmill Belt is the surface you run on. The thicker the belt, the less impact on your joints. At least 2-ply (1 inch) recommended.

Our Rating

Rating: 86.3/100. The Life Fitness F1 Smart Treadmill is one of the better folding treadmills on the market. Unlike cheap folding treadmills, the F1 offers the quality of a good traditional treadmill. It weighs a hefty 259 pounds but can easily be folded and wheeled away after workouts. Its full price is $2,298.

Key points are a 2.5 HP motor, an impressive FlexDeck cushioning system, a 55″ track, a power incline with range of 0.5% to 12%, and wireless heart rate monitoring. Additionally the F1 Smart Treadmill is iPod-compatible and can connect with popular fitness apps.

The Life Fitness F1 is very similar to the F3, which costs $299 more. The F3 has a more powerful motor and includes a choice of two consoles, each with at least 12 preset workout programs.


The Life Fitness F1 is a sturdy folding treadmill priced at $2,298. It easily outperforms typical folding treadmills and fares well against traditional treadmills too. The F1 has good motor power, very effective cushioning and wireless heart rate monitoring. It has seven preset workouts and can recall your preferred speed and incline for Quick Start walking, jogging and running. Additionally it can connect with popular fitness apps; one option is using LFConnect to transfer workout programs to the treadmill. Overall the F1 Smart Treadmill is intended for shoppers who would take advantage of the mobile options. For other shoppers the F3 with plenty of built-in workouts is a more popular choice.

Workout Programs

The F1 treadmill computer has an LED display with blue lighting. It has seven preset programs to simplify training with specific goals for calorie burn, distance and other variables. The Quick Start feature recalls your preferred settings for speed and incline. The big strength though is connecting with mobile apps for guided training and automated data tracking. The LFConnect app is one option for accessing additional treadmill workouts.

Life Fitness F1 Smart Features

Whether folding or non-folding, Life Fitness treadmills use FlexDeck cushioning. The FlexDeck system helps reduce the impact of exercise on your joints, which lowers the risk of injury and promotes your endurance. It reduces the stress of exercise by up to 30% compared with asphalt surfaces.

The comfortable running surface can also be power-adjusted to simulate uphill running. The track can incline if half-degree increments up to 12 degrees.

A dock for your iPod is placed at the lower center of the console. The F1 is compatible with iPod Nano 5th generation + below, iPod Classic, iPod with Video and first and second generation iPod Touch.

To help you train efficiently, the F1 can track your heart rate wirelessly or with touch sensors.

A “green” feature on Life Fitness treadmills is their self-adjusting motors. This treadmill can run constantly at 2.5 HP, but if you weigh less it will use less energy.

This treadmill is a space-saver; it’s designed to let you easily fold the deck upward. Transport wheels are attached.

Warranty & Guarantee

The Life Fitness F1 Smart Treadmill warranty includes:

– Frame: Lifetime

– Deck: Lifetime

– Motor: 10 years

– Parts: 5 Years

– Labor: 1 year


The F1 Smart Treadmill is a very good folding treadmill with a long warranty on its parts. Its 2.5 HP motor and 55″ track are ideal for walkers but could be limiting for runners. This unit doesn’t offer the built-in workout variety of the F3, but options are endless if you connect mobile fitness apps.

The F1 is high quality but faces good competition from the F3, which costs little more. We also like the feature-rich NordicTrack Commercial 2950, which has a stronger motor and a lower sale price.
