Do you need a virtual trainer feature? Experienced trainees can typically set their own workout goals based on their needs and fitness levels. That's more of a challenge for novices, however, who might be best served by a heart-rate monitor or fitness app that can create a plan for them.
How often will you use it? Like all products, some heart-rate monitors are more durable than others. If you plan to wear your monitor on a daily basis, investing in a unit that can withstand the wear and tear of day-to-day activities is worthwhile.
Where will you use it? If you plan to run in harsh weather with your heart-rate monitor, it needs to be weatherproof and durable. Most are water-resistant to 30 meters, though few are actually waterproof. Don't plan on taking a Bluetooth heart rate monitor on a swim as Bluetooth signals don't pass through water very well.
Do you want to track long-term progress? Some heart-rate monitors can upload training results to a website, which allows users to graph and track heart rates, workout times and calories long term. With some units, uploading data to a computer or website requires an optional upload module that ups the total cost. Wireless heart rate monitors upload their results to an app, which provides tracking as well.
Do you want to calculate calories burned? If weight loss is your ultimate goal, you'll most likely want to track calorie expenditure during each workout. That's a capability of most, but not all, heart-rate monitor computers.
How hard a workout do you want or need? Training at different intensities and heart rates will produce different fitness results. To burn the most fat, experts at the International Sports Sciences Association recommend working at 55 percent to 85 percent of your maximum heart rate, which is 220 beats per minute (bpm) minus your age. For example: If you're 25 years old, you should keep your heart rate between 108 and 165 bpm during exercise.
Can you swim with a heart-rate monitor? Technically, yes, at least with any heart rate monitor rated to be water resistant to 30 meters, and that includes the Best Reviewed Polar FT60 and Polar FT1, as well as the Timex Ironman Race Trainer (which is water resistant to 100 meters), Suunto Quest and others. However, most manufacturers warn that touching any button while underwater can harm the display's water integrity, and while we see lots of feedback from users saying that they have had great success swimming with their heart-rate monitors, we also note complaints from others that report damage, fogging, etc. after swimming. Using a wireless heart rate sensor and sending data to a poolside device is another alternative, but keep in mind that Bluetooth does not work well under water. Instead, opt for a sensor that uses ANT+ as well. ANT+ is compatible with some current Android smartphones, or you can buy an adapter for use with other Android phones or the iPhone. The Best Reviewed Polar H7 does not support ANT+, but other top choices, including the Wahoo TICKER, do.
