Today, we look at the Polar Ft4 vs Polar Ft7, two similar models with a world of difference between them.
Heart rate monitors have become an athletic staple around the 1970s when the company Polar developed the first wireless model.
These monitors measure the speed at which the athletes’s heart is beating, which can tell the individual several bits of crucial information about their stress, health, and levels of exertion.
Polar continues to be one of the most major corporations creating and selling portable heart rate monitors.
Aside from the price, the biggest difference is that the FT7 has a larger memory and displays more information surrounding your workout.
As technology progresses, the monitors can now be work around the wrist like a standard watch. Their devices are so well-made that they continue to be used in scientific studies all around the world.
With this in mind, why should an athlete get a heart rate monitor, and which model is best?

Polar Ft7 vs Polar Ft4 Comparison:
As mentioned, these two heart rate monitors are similar but also quite different.
Both have great reviews, but how do they compare in sheer usefulness and technical parameters?
This chart breaks it down.
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.
Polar Ft4 vs. Ft7 Wrap-Up
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.
