Best features: Garmin HRM Pro - Heart rate monitor
Garmin HRM Pro transmits real-time heart rate data over ANT+ and Bluetooth connectivity, giving you ample training options. It enables you to track heart rate 24/7 on compatible Garmin devices, online training apps, and fitness equipment at the gym.
In addition to heart rate, the HRM Pro captures running dynamics that can help you improve your form. That includes vertical oscillation, ground contact time, stride length, vertical ratio, and more. This device can store heart rate data during swimming or other activities while your Garmin wearable is out of range, then sends that data to your wearable once the activity is finished.
It also functions as an activity tracker and can store steps, calories, and intensity minutes, then syncs those stats to your watch or device. This monitor features a small, lightweight design with a soft, comfortable strap. The user-replaceable coin cell battery lasts up to one year, depending on usage.
On the downside, this monitor is pricey, but you're paying for the additional running dynamics and activity tracking on top of heart rate monitoring.

Best fitness tracker: Fitbit Charge 5
Fitbit Charge 5 is by far Fitbit's most advanced tracker to date. It offers comprehensive health and fitness monitoring, including features to help you stay on top of your heart health like ECG, 24/7 heart rate monitoring, and heart rate variability tracking.
Keep a finger on your pulse — literally, with a compatible ECG app that assesses your heart for rhythm irregularities. It'll track and store these results so you can share them with your doctor if you need to.
The heart rate variability feature helps you understand if your body shows potential signs of stress, illness, or fatigue based on your past month's trends in the variation of time between each heartbeat.
Get the most out of your workouts with Active Zone Minutes — a feature that gives your wrist a buzz when you reach your target heart rate zones. Charge 5's has a built-in GPS that records your workout routes and then shows you how your heart rate changed along those routes in your workout intensity map in the Fitbit app.
It delivers up to seven days of battery on a full charge depending on your usage. On the downside, it's a bit pricey compared to the other trackers on this list, but you're getting a lot more than just a heart rate monitor, so we feel it's worth the higher cost.
