Whether you’re an elite athlete, a weekend warrior, or someone who just wants to hit their 10,000 steps before the dog starts judging you, the world of wearables and fitness tech can be both exciting and a bit overwhelming.
With dozens of gadgets promising better performance, improved recovery and smarter training, how do you know what’s actually worth strapping to your wrist (or chest)?
At LBSM, we regularly see patients who use wearables to monitor everything from heart rate to sleep to stress – sometimes all in the same device. Used well, this tech can massively enhance enjoyment, accountability, and consistency with training. Used poorly, and it can lead to burnout, obsession, or just gathering dust in a drawer.
So here’s our breakdown of the top 10 most popular wearables and apps in the UK fitness world right now, what they’re great at, what they’re not, and how to make the most of them.

What it struggles with:
- Battery life (around 1-2 days)
- Not as sport-specific or durable as some competitors
- GPS isn’t as precise in dense areas or for long-distance trail running

How Can Wearables and Apps Actually Help?
1. Accountability & Motivation
Whether it’s the Apple Watch telling you to stand up, or your mate giving you kudos on Strava, tech can keep you engaged when motivation dips.
2. Better Consistency
Seeing your training history builds momentum. Logging 3 runs a week feels great – especially when you hit a streak.
3. Smarter Recovery
Tools like WHOOP and Oura focus on recovery, which is often the missing piece for those who train hard but stagnate or get injured.
4. Enhanced Enjoyment
Route planning apps like Komoot help you find beautiful trails. Zwift gamifies indoor sessions. It all adds a bit of joy back into your routine.
5. Tailored Performance
Advanced wearables track VO2 max, lactate threshold, and even gait metrics. These can guide personalised plans and prevent overtraining.
Final Thoughts
No wearable or app will make you fitter by itself. But used wisely, these tools can enhance your experience, keep you accountable, and make your training more efficient and enjoyable. Whether you’re aiming for a marathon PB, building back from injury, or simply trying to move more each day – there’s a bit of tech out there that can help.
Just don’t forget – sometimes the best data is how you feel. Listen to your watch, but also listen to your body.
Let us know what you’re using and loving – or if you need help interpreting all those graphs and metrics, we’re here for that too.
