Polar FT4 Review:

POLAR FT4M Heart Rate Monitor One Color One Size

 The Polar Ft4 is one of the highest rated products from the company. The monitor’s face is broad and looks like a square with rounded side edges.

The screen itself is square and displays information in blocky, black letters for easy reading. It can be found in multiple colors, including pink, blue, and green.

The Ft4 tracks continuously, meaning the data is stored.

A user can therefore figure out their average rate during any activity, how high the rate gets during exercise, and what their lowest point sits at.

Runners can additionally set target zones to reach with different parameters.

The Polar Ft7 displays more information, has a better memory, and can connect to more machines. 

It is also lighter and people tend to find it more comfortable. However, it is also more expensive than the Ft4.

For some runners, spending a little bit more money might be too much to spend on a heart rate monitor, while it might work for some others.

Benefits of a Heart Rate Monitor

According to Live Science, heart rate monitors serve an important function when it comes to exercise. The majority of workouts and exercises can be divided into separate intensity zones which determine how hard a person is working.

Athletes and runners can estimate which zone they are in by checking their heart rate, which is a more objective estimate than checking how hard someone is breathing.

The American Heart Association knows that people should maintain a certain heart rate for optimum health. Going too high puts people at risk of damage, death, and heart attacks.

Going too slow indicates that a person is not working hard enough and might not receive the benefits of exercise.

A heart rate monitor can help a person determine whether or not they are in that sweet spot in the middle.

Runners can figure out their maximum heart rate by following instructions from the Mayo Clinic, which state that a person’s maximum should be no higher than their age subtracted from 220.

The chart below demonstrates some of the maximum rates for athletes of different ages.

AGE

MAXIMUM RATE of Beats per Minute (BPM)

25

220-25=195

30

220-30=190

35

220-35=185

40

220-40=180

45

220-45=175

50

220-50=170

So, a heart rate monitor keeps people in a healthy athletic range.

It can also tell a runner whether they are actually working hard enough to make a difference in overall athleticism and endurance, or whether they are going too easy on themselves.

Conclusion

In general, the Polar Ft7 is a better fit for runners because of its extra features, greater memory, and ability to transfer information.

It’s not too much more expensive than the Ft4 to be outrageous, but many people might be unwilling to spend over $100 on a heart rate monitor, and that’s okay.
