EZ Fold Technology

The EZFold Technology from the LifeSpan brand, as the name implies, makes it very simple to fold for compact storage as well as moving from place to place.

EZFold uses special built in mechanics (hydraulic shock system) to assist with the safe folding and unfolding.

If you are living in a smaller space, you will know the importance of a treadmill that can fold easily. You will want to tuck it into a corner after you have finished your workout activity.

Cushioning and Bounce

This model is equipped with 8 independent compression shock absorbers.  This means that your knees, joints and back will thank you by reducing the stress on your body.

Treadmills that bounce up and down as soon as you start moving are annoying. You don't want to bounce as you are running. This can make the entire machine feel flimsy, and the noise pollution makes things even worse.

You want something that does not bounce a lot, and that is where this treadmill wins.

It does not bounce at all.
