Independent testing
How much independent testing exists for each elliptical
Of the 8 ellipticals we track, 2 have been physically measured by at least one independent lab. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| ProForm Carbon EL | 1 | 1 | 2 |
| Sole E25 | 1 | 1 | 2 |
| Bowflex Max Trainer M9 | 0 | 0 | 1 |
| Horizon EX-59 | 0 | 0 | 2 |
| NordicTrack AirGlide 14i | 0 | 0 | 1 |
| NordicTrack Commercial 14.9 | 0 | 0 | 1 |
| NordicTrack FS14i FreeStride Trainer | 0 | 0 | 1 |
| Sole E35 | 0 | 0 | 2 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Ellipticals buying guide and the reviewers we cite.
