Amazon's Prime Day sale is on its last leg today, wrapping up tonight at midnight PDT (3 a.m. EDT). We've been combing the entire site for the best, most worthwhile deals on our favorite products, and more have been popping up over the course of the two-day sale. And we just found one of the best ones yet: A chance to save $140 on one of our favorite under-desk treadmills, the WalkingPad S1.
You may already know where we stand on sitting all day at home or in the office, but if you don't, here's the abridged version: we tend to prefer against it. Taking some time to stand and move your legs during the day can pay dividends for your training, and having an under-desk treadmill can make logging some midday steps easier than ever.
The S1, one of our favorites, offers a super sleek profile that'll undoubtedly save you some space in your work area. On top of that, it can fold in half, allowing you to tuck it away more tidily than ever without worrying about a dedicated spot for it. Bonus features on the S1 include a child lock that remembers your stride and doesn't turn on for anyone else's, as well as an automatic speed-changing mode that adjusts to your walking pace hands-free.

The high-sensitivity sensor under the belt works by dividing the track into three distinct sections: The front end is the acceleration zone, which indicates that you're moving slower than the belt speed, the rear end is the deceleration zone, which indicates the opposite, and the middle is the "uniform velocity zone," which detects when you've settled into the right pace. There's no input needed other than your steps, and you can speed up and slow down on a whim, no problem.
Ultimately, seeing a 20 percent markdown on a treadmill isn't a treat we get often, especially on higher-quality models like this one. It's the biggest discount the S1 has gotten from Amazon all year, and we estimate that it'll be a long while before we see the price that low again.
