From smart watches to smart mirrors, technology has taken over the fitness industry with as much verve as it has taken over every other industry. And, in some cases, it’s made it easier to train, lift, stretch, run, sleep, rest, and reset every day in 2025.
This year, Mashable tested a lot — and I mean a lot — of fitness tech. I trained for and ran the New York City Marathon with seven fitness trackers. We tried all the smart rings including, and beyond, the Oura ring. We tried every sleep tracker we could get our hands on and put every pair of headphones we could find in our ears for a good workout. We tested the fitness mirrors, and we built out tech-forward home gyms.
Here are four of the best bits of fitness tech from 2025.
Apple Watch Ultra 3
The Apple Watch Ultra 3, released in September, was one of my favorite trackers I tested while training for, and especially running, the New York City Marathon. Its screen is massive, which can be annoying for daily wear, but rules for trying to read metrics during a workout. The battery life is significantly improved over its predecessors, and it’s surprisingly comfortable.
While the workout metrics are straightforward, they’re also very reliable. If you’re looking for fitness tech that also doubles as lifestyle tech, the Apple Watch Ultra 3 is the way to go.

The Whoop MG
The Whoop MG 5.0, released in May 2025, was rated the best sleep tracker by Mashable’s Samantha Mangino, who noted that while there’s a lot of data a sleepmaxxer might not be into, it’s remarkably comfortable and is “best for someone who wants to be told what to do regarding sleep.”
Anyone who wants to prioritize their fitness knows that sleep is the number one thing you can do to make your workouts go the extra mile. I wore the Whoop during my marathon journey and found that its tracking is elite for other athletic endeavors as well, such as indicating how strong your body battery is and providing recommendations for enhancing your recovery.
It doesn’t have a screen, so there’s no GPS or heart rate feedback data during workouts, but that also means there’s no annoying text notifications while you’re hanging out with family.
While the subscription model is financially frustrating, Whoop’s depth of recovery data makes it arguably one of the best tools for understanding your body.

Beats Powerbeats Pro 2
These headphones, released in February, were reviewed by Mashable’s Samantha Mangino and Alex Bracetti as the top headphones for working out. The duo said these are “best for fitness users who want the most boxes checked.” The controls are accessible, there’s convenient multi-platform support, they’re durable, have engaging sound and noise cancellation, are comfortable and fit well, and offer long playtimes.
Simply a lovely app to track workouts and talk about them with friends. Nothing about Strava is particularly new for 2025, but its integration with fitness trackers works seamlessly, and you really can’t get mad at its dedication to consistency.
