How an Under Desk Elliptical Works
An under desk elliptical keeps your feet on two pedals that glide through a short stride while you stay seated. Magnetic resistance slows the flywheel with a magnetic field, so there is no pad to wear out and no friction noise. Sunny says it can help circulation, joint range of motion and lower-body muscular endurance.
Can you pedal an under desk elliptical backwards? Yes. Sunny says you can pedal both forwards and backwards on this machine.

Who Should Buy It and Who Should Skip It
Buy it if you want low-impact leg work at a desk or on the sofa.
Best for:
- Home-office workers who sit most of the day
- Anyone who wants low-impact leg work during TV time
- Small spaces that cannot fit a full elliptical
Not a fit if:
- You want a full-body workout with moving arm handles
- You want a long, standing stride
- You want it for a commercial or shared facility
This elliptical is for home use only, and commercial use voids Sunny's warranty.
