As TechRadar's resident fitness guinea pig, I'm on the hook every time a new fitness gadget needs to be tested in-house. Consequently, I've tried loads of new fitness gadgets, from the best heart rate monitors to smart rings, and if I'm not at my laptop in TR Towers, I can usually be found in the gym or on a run.
However, by far the most common categories are fitness trackers and smartwatches, wrist-based devices used to track exercise, sleep and recovery. So far, I've tried 10 of these in 2025.
