Total lower-body results: Tone, strengthen and define your calves, hamstrings, quads, glutes and even your core! As promised, the Cubii easily fit under my desk, and the chair stopper prevented my chair from rolling away. I regularly go to the gym and use my stationary bike each morning, and have reasonable fitness levels.

When it came time to actually use the device, I was impressed by the smoothness of the elliptical motion and how quietly the flywheel operates.

Nevertheless, if the benefits of the Cubii are in line with your goals and you can afford to purchase the device, it’s worth giving the Cubii a try.For the 30-minute fitness test I did with Cubii, my average heart rate was 90 bpm and my maximum was 116 bpm, recorded in the five minutes I was on the highest resistance and pedaling my hardest. Assembling the device was fairly straightforward and took less than 10 minutes, though you do need a screwdriver to install the pedals.

Similarly, if you tend to fidget or get restless, the Cubii could help you get the wiggles out while working or watching a movie. My only complaint on the tech side is that you have to manually input your resistance level on the app, which is rage-inducing if you forget and spend ten minutes pedaling at level eight but only get the credit for level two.

The downside—which, if you've ever used an exercise machine you can probably guess—is that the lower the setting you use, the fewer calories you burn. The Cubii elliptical is a relatively new product that offers an aerobic workout from the comfort of your desk, couch, or chair. Still, maintaining that pace while working became a problem—I kept finding myself getting distracted and then several minutes later realizing I'd stopped pedaling. It’s also fairly quiet, so you can use the machine without getting distracted by the sound of a fan or wheel. Due to the angle at which your legs and feet fit into the pedals, the Cubii will primarily engage the muscles in your lower legs like your calves and tibialis anterior, which is the muscle that runs along your shin.
