Best And Worst Fitness Devices Of 2025
Generally, You Should Be Looking For Devices That Are Both Accurate And Reliable. Normally, I Would Say The Garmin Forerunner 570 Is A Great Choice Because It Has An Exceptionally Accurate Heart Rate Sensor. Usually, This Sensor Is Near-Perfect, And In Tests Against A Chest Strap, The Readings Were Almost Identical, Which Is Pretty Impressive.
Most Accurate: Garmin Forerunner 570
Obviously, The Garmin Forerunner 570 Impressed Me With Its Elevate Version 5 Sensor, Which Was Unexpectedly Accurate. Naturally, This Level Of Accuracy Is Important For Athletes Who Need To Monitor Their Heart Rate Closely. Typically, The Forerunner 570’s Readings Were Almost Identical To Those Of A Chest Strap, Which Is The Gold Standard For Heart Rate Monitoring.
Coolest Concept: Core 2 Thermal Sensor
Apparently, The Core 2 Thermal Sensor Is A Game-Changer For Runners Dealing With Summer Heat. Usually, This Device Clips Onto Your Heart-Rate Chest Strap And Measures Your Body Temperature Using A Temperature Sensor And A Heat-Flux Sensor. Normally, It Provides Real-Time Feedback On Whether You’re Getting Enough Heat Training Or Need To Take A Break, Which Is Invaluable For Athletes.
How It Works
Generally, The Core 2 Thermal Sensor Is Easy To Use And Provides Accurate Readings. Normally, You Just Clip It Onto Your Chest Strap And Start Your Workout, And It Will Provide You With Real-Time Feedback On Your Body Temperature. Obviously, This Is Important For Athletes Who Need To Monitor Their Body Temperature Closely.
Runner-up: Data Fitness Connector (DFC)
Usually, The Data Fitness Connector (DFC) Is A Useful Device For Peloton Bike Owners Who Want To Track Their Workouts Without A Subscription. Naturally, This Small Box Connects To The Back Of Your Peloton Bike And Transmits Power Data Via Bluetooth To Your Fitness Watch Or Phone. Typically, It Doesn’t Provide Speed Or Distance Data, But It Effectively Logs Your Workouts And Provides An FTP Estimate, Which Is A Good Alternative To The Peloton Subscription.
Best Upgrade and Best Overall: Coros Pace 4
Obviously, The Coros Pace 4 Is The Best Overall Fitness Watch Of 2025. Generally, Coros Watches May Lag Behind Garmin In Features, But They Make Up For It With Affordability And Reliability. Normally, The Pace 4 Introduces Several Upgrades, Including An AMOLED Screen, Improved Battery Life, And A New Button And Microphone, Which Enable Voice Pins And Voice Training Logs.
Runner-up: Pixel Watch 4 Charging Features
Apparently, The Pixel Watch 4 Introduced Ultra-Fast Charging, Which Is A Significant Upgrade. Usually, The Watch Can Charge From 3% To 97% In Just 31 Minutes, Making It The Fastest-Charging Smartwatch On The Market. Naturally, It Also Comes With A New Magnetic Dock-Style Charger That Is More Convenient Than Previous Versions.
Best Whoop Alternative: Amazfit Helio Strap
Generally, The Amazfit Helio Strap Is The Best Alternative To Whoop. Normally, While Garmin And Polar Also Released Screenless Fitness Trackers, The Amazfit Helio Strap Stands Out For Its Affordability And Reliability. Obviously, At Just $99, It Offers Similar Functionality To The Polar Device But At Half The Price, Which Is A Good Option For Those Who Want A Screenless Tracker Without The Whoop Subscription.
Biggest Disappointment: Powerbeats Pro 2
Usually, The Powerbeats Pro 2 Was The Biggest Disappointment Of The Year. Apparently, The Idea Of A Heart-Rate Sensor In Earbuds Is Intriguing, But The Execution Fell Short. Naturally, The Sensor Doesn’t Make Good Contact With The Skin Unless Your Ears Are A Specific Shape And Size, Leading To Unreliable Heart-Rate Data For Some Users, Which Is A Significant Drawback.
