Whether you're want to track how many steps you do every day, get into running or just monitor your health in general, it's important to choose a fitness tracker that suits your needs. 

To help you on your search, we put fitness trackers to the test, considering everything from how easy they are to set up and use, to how long the battery lasts, whether they motivate us to exercise more and what features they have that makes them stand out from other options on the market. 

We tried out popular brands such as FitBit and Apple, and tested each watch over a number of days while doing a range of activities, from walking to running to at-home workouts, to bring you a round-up of the best.

There’s a reason the best Fitbits have been worn religiously for over a decade and that’s because they're so user-friendly, even for technophobes. That’s definitely true for the FitBit Charge 4 - in fact, it’s the main reason we rate it so highly. 

This fitness tracker focuses on boosting your health and emotional wellbeing – essential to balance if you want to push your fitness boundaries further. 

It’s definitely worth the investment, considering it’s waterproof and has a heart-rate monitor, built-in GPS and the ability to track your sleep. But the main reason it scores so highly is that it’s really easy to use. There’s no user manual in the box as you simply don’t need one. The functions are easy to select by simply swiping up, down, left or right. It tracks all the basics when you exercise and you can even set goals before you set off, to really boost your workout. 

Plus, not only can you review your sleep, track your menstrual cycle and take time out for a quick breathing meditation reset, but the ever-expanding Fitbit community means you can share as much or as little of your progress and wellness with other like-minded individuals. This means you’ll always feel like part of a team, even when you’re doing at-home workouts alone or tackling trails on your own.

This includes Siri and the ability to reply in iMessage on the move. But that’s not all – add into the mix a medical-grade ECG heart monitor, automatic detection to know which sport you want to track and a nudge if you haven’t moved enough each hour. Plus, this wearable watch also looks out for your health, with a menstrual cycle tracker and decibel monitor, so you know when you need to protect your hearing. The only thing missing is its own sleep tracker, although you can download an app for that.

Battery lasts: 7 months
Water-resistant: up to 10m
Available colors: Black & red

Reasons to buy
+Easy set-up+Good for group fitness
Reasons to avoid
-Connection issues-Can be uncomfortable

Not everyone wants to wear a fitness tracker around their wrist, and if this sounds like you then you're going to love our top budget pick.

Instead of wearing it around your wrist, the red Myzone MZ-3 strap fits around your chest and connects to your smartphone via Bluetooth. This type of external strap can give ultra-accurate heart rate readings. What's more, your workout score on this fitness tracker is based on the effort you put in and the heart-rate intensity you reach. This type of tracker is addictive and focusing on heart rate is a great way to boost your fitness, whether you're doing a walking workout or trying your hand at something new like boxing for women. Plus, the fact it only needs charging every seven months means if you are using it in the gym, you can keep it in your sports bag so you'll never forget it. 

The only downside to this fitness tracker is that it doesn't have GPS, and if that's a deal-breaker for you then it's best to stick to a smartwatch instead.

The technology is medical-grade and trustworthy. And it's a great pick if you're looking for a stylish way to track your daily activity. 

There’s a special hand on the analog watch face that tracks daily steps, which moves as you do and then automatically resets at midnight. You’d be surprised how much it can spur you on to do those last few hundred steps to stay on target – helping you keep your heart healthy in the process.

Unlike the other fitness trackers, this watch runs on a coin cell battery which you'll have to manually change every time your battery runs out.
