We have been training on our WalkingPad under-desk treadmills and pushing WalkingPad running treadmills to their limits for a while. WalkingPad treadmills are great for walkers and runners who have small spaces or want to store their treadmills out of sight. They do not incline but connect to the free KingSmith app for more training options. Read our overview of WalkingPad's under-desk and running treadmills to find the right one for you.
