I have heard the phrase "sitting is the new smoking" more times than I can count, and as someone with a sedentary job, I can sometimes leave the office feeling a little bit lazy for having sat down all day. And when I’m sitting all day, in the afternoon, I start to feel pretty sluggish.

I tried just standing at my desk in the afternoon, but I just noticed that my posture was suffering. I heard that one of the best under-desk treadmills can enhance productivity and get you moving, so I tested the WalkingPad Z1 and everything changed. I’ve been hitting 10,000 steps every single day without leaving my laptop and avoiding the afternoon slump.
