MyZone Review: Tested Across 8 Weeks in UK Gyms

MyZone is one of the most talked-about heart rate wearables in UK gyms right now — and after 8 weeks of hands-on testing across multiple studios and box gyms, we’ve got a brutally honest take on whether it actually delivers. Spoiler: the effort-based system is genuinely clever, but it’s not without its frustrations.

In this MyZone review, we cover everything from heart rate accuracy and MEPs scoring to app usability, gym compatibility, and whether the price tag is justified for everyday UK gym-goers. We’ve done the legwork so you don’t have to.

What Is MyZone?

MyZone is a heart rate-based fitness wearable system developed by Myzone Group Ltd, a company with strong roots in the commercial fitness industry. Rather than simply counting steps or calories, MyZone tracks your effort relative to your personal maximum heart rate, translating that data into a points currency called MEPs (MyZone Effort Points).

The hardware — typically a chest strap or arm pod — pairs with the MyZone app and syncs directly with compatible gym equipment and studio screens in hundreds of UK fitness facilities, from independent box gyms to national chains. This live display element is a big part of what sets MyZone apart: your effort zone appears on communal screens during classes, creating a genuinely motivating (and occasionally humbling) group experience.

The system is built around five colour-coded effort zones — grey, blue, green, yellow, and red — each corresponding to a percentage of your maximum heart rate. It’s an approach that rewards consistent effort over raw fitness levels, making it one of the more inclusive fitness wearables on the market. If you’re also interested in how other trackers stack up, our Fitbit review is worth a read for comparison.

Key Features

MEPs: Effort-Based Scoring That Actually Motivates

The MEPs system is the beating heart of the MyZone experience. Instead of rewarding raw output — which inherently favours fitter users — MEPs rewards effort relative to your own maximum heart rate. Spend more time in higher zones, earn more points. This levels the playing field considerably in group settings, meaning a beginner working at 85% of their max earns the same MEPs as a seasoned athlete doing the same. According to MyZone, 1,300 MEPs per month is the recommended target for good cardiovascular health. This gives users a concrete, meaningful goal to chase.

Live Gym Display Sync

One of MyZone’s standout features is its integration with gym display screens. In partner facilities across the UK, your live heart rate zone and MEPs appear on a wall-mounted screen during workouts. This creates real-time accountability and — in group class settings — a surprisingly effective motivational nudge. During our testing in three different gyms, the sync was reliable and near-instant, dropping connection only once across multiple sessions.

Heart Rate Accuracy and Hardware Options

MyZone currently offers several hardware options, including chest straps (MZ-3 and MZ-Switch) and the wrist-based MZ-Switch which can also be worn on the arm or chest. Chest-based tracking is widely regarded in the industry as more accurate than optical wrist sensors, and our testing bore this out — the chest strap readings were consistently close to a medical-grade pulse oximeter during high-intensity intervals. The MZ-Switch offers more flexibility for those who find chest straps uncomfortable during certain activities.

App and Social Features

The MyZone app provides detailed post-workout breakdowns, monthly MEPs tracking, challenge participation, and a social feed where you can follow friends and gym members. Challenges — both gym-wide and individual — add a gamified layer that goes beyond what most basic fitness wearables offer. The app integrates with Apple Health and Google Fit, broadening its compatibility. It’s not the slickest UI we’ve seen, but it’s functional and consistently updated. For a contrasting app experience, see our Garmin Connect review.

How MyZone Compares

Pros and Cons

• ✅ Effort-based MEPs system is genuinely inclusive — rewards hard work regardless of fitness level
• ✅ Live gym screen integration is motivating and sets MyZone apart from virtually every competitor
• ✅ Chest strap accuracy is excellent — more reliable than optical wrist trackers during high-intensity training
• ✅ Extensive UK gym network — widely adopted in independent studios, box gyms, and leisure centres nationwide
• ✅ Monthly MEPs targets provide meaningful, trackable goals rather than vague step counts
• ✅ Social and challenge features add genuine accountability that keeps you coming back
• ✅ App integrates with Apple Health and Google Fit, so your data isn’t siloed

• ❌ Full value depends on your gym being a MyZone partner — solo outdoor users miss most of the best features
• ❌ No sleep tracking — a notable omission compared to Whoop and newer smartwatches
• ❌ App interface feels dated compared to Whoop or Garmin Connect — navigation can be clunky
• ❌ Chest strap comfort varies — during swimming or certain floor-based exercises, it can shift or feel restrictive
• ❌ Battery life on the MZ-3 is around 4 months, but replacement batteries add a minor ongoing cost

Pricing

MyZone’s pricing model is refreshingly straightforward for the hardware side: you pay once for the device, and the core app is free to download and use. The MZ-Switch (the most versatile option, worn on chest, arm, or wrist) is priced at approximately £109–£129, while the classic MZ-3 chest strap sits closer to £89 — though prices fluctuate, so always check directly.

Some gym operators who use the MyZone system may bundle the device cost into a membership package or offer group discounts, so it’s worth asking at your gym before purchasing independently. There is no mandatory monthly subscription for individual users — the app’s social and tracking features are included.

Compared to Whoop 4.0, which charges from approximately £30 per month on top of device costs, MyZone represents significantly better value for money if you’re primarily a gym-based trainer. Polar H10 is similarly priced on hardware but lacks the gym integration ecosystem that justifies MyZone’s premium over basic chest straps.

Who Is MyZone Best For?

Perfect For:

• Regular gym class attendees who want real-time effort feedback displayed during sessions — the live screen sync is transformative for group motivation
• Beginners building consistency who benefit from the MEPs monthly target system as a clear, achievable goal that doesn’t require advanced fitness knowledge
• Personal trainers and gym operators looking to increase client engagement and retention through gamified accountability — MyZone has a dedicated professional platform
• Competitive gym-goers who thrive on leaderboards, social challenges, and seeing how their effort stacks up against peers
• People returning to fitness after a break who need an encouragement-first system that rewards effort, not just performance

Not Ideal For:

• Outdoor or solo runners who won’t benefit from gym screen sync and may find better value in a GPS-based wearable like Garmin — see our Amazfit GTR 4 review for an alternative
• Sleep and recovery-focused users who need overnight tracking — MyZone simply doesn’t offer this, and Whoop 4.0 would serve them better
• Swimmers who need consistent underwater accuracy — the chest strap can shift, and the device has limited waterproofing claims for sustained submersion
• Gym-hoppers without a MyZone-partner gym nearby — if your local facility doesn’t use the system, you’ll lose the standout features that justify the device

Our Verdict

After 8 weeks of real-world testing, MyZone earns its reputation as one of the most effective gym accountability tools available in the UK today. The MEPs system is genuinely smart — it democratises group fitness by rewarding effort over ability, and the live gym screen integration delivers a motivational experience you simply can’t replicate with a standard fitness wearable.

It’s not perfect. The app could use a design refresh, sleep tracking is absent, and its value is heavily dependent on training in a MyZone-partner facility. But for gym-based users who want structured effort tracking and community accountability, it’s hard to beat at this price point.

We’d confidently recommend MyZone to anyone who trains in a class environment or wants a heart rate monitor that goes beyond raw data to genuinely change behaviour.

Frequently Asked Questions

How accurate is the MyZone heart rate monitor?

The MyZone chest strap (MZ-3 and MZ-Switch in chest mode) is highly accurate, using electrical heart rate detection rather than optical sensors. In our testing it tracked closely alongside a medical-grade reference device during high-intensity efforts. Optical wrist-based tracking is generally less precise during vigorous exercise, which is a known industry-wide limitation rather than a MyZone-specific one.

Do I need a MyZone gym membership to use it?

No — MyZone works as a standalone heart rate tracker and the app is free to download. However, the most compelling features, including live gym screen sync and group challenges, require your gym to be a MyZone-partner facility. Check the MyZone website’s gym finder to see if your local gym is registered before purchasing.

What are MyZone MEPs and how do they work?

MEPs (MyZone Effort Points) are earned based on the time you spend in each heart rate zone relative to your personal maximum. Higher effort zones earn more MEPs per minute. According to MyZone, 1,300 MEPs per month aligns with current guidelines for cardiovascular health. The system rewards sustained effort rather than raw performance, making it fair across all fitness levels.

Is the MyZone app free?

Yes, the MyZone app is free to download on iOS and Android. Core features including workout tracking, MEPs logging, and social connections are available without a subscription. Some premium or gym-operator features may require additional access through your fitness facility. Check myzone.com for the most current app feature breakdown.

How does MyZone compare to a Fitbit or Apple Watch?

MyZone is purpose-built for gym effort tracking and community accountability, whereas Fitbit and Apple Watch are broader lifestyle wearables. MyZone’s chest strap is more accurate during intense workouts than optical wrist sensors, and the gym screen integration is unique. However, Fitbit and Apple Watch offer sleep tracking, daily activity monitoring, and smartwatch features that MyZone doesn’t attempt to match.
