Welcome to the deep dive. Today we're focusing on the 4th
Frontier X2 Heart Rate monitor. We're using a really detailed
review from the 5K Runner as ourguide.
Right. And this isn't just, you know, a
typical gadget review. We want to explore what this
kind of advanced wearable tech means for heart health,
especially for active people. Exactly.
(00:20):
Can something like the X2 actually give us useful insights
that go beyond, say, just step counts or basic heart rate
zones? That's the core question.
The reviewer, the 5K runner, actually gave it a pretty high
score, 87%, so generally positive.
Oh good. Score.
Yeah, and they even mentioned a discount 25% off using the code
HE5K RUNNER, useful if you're interested.
(00:42):
Good tip. But really, our mission here is
to understand what this device can tell us about our hearts
during exercise and maybe even, you know, throughout the rest of
the day. OK, so let's start with the
basics. For anyone listening who hasn't
heard of it, what is the 4th Frontier X2?
What makes it stand out? So fundamentally, it's a second
Gen ECG sports strap launched in2023.
ECG, so electrocardiogram. Exactly.
(01:04):
That's the key differentiator. It does the sports tracking,
accurate heart rate like you'd expect, but it also provides ECG
grade monitoring of your heart'selectrical activity.
It's trying to be both a high performance sports tool and a
serious heart monitor. Interesting combo.
What does it look like? Is it comfortable?
Easy to use. Well it uses 2 chest straps
(01:26):
which helps get that really goodskin contact needed for accurate
readings, both HR and ECG. OK, like some traditional heart
rate monitors? Right, and these straps connect
to a small clip on pod. That's the brain, basically.
It has a button, a little colourdisplay and a side charting
port. Pretty straightforward.
And the battery, how long does it last if it's doing ECG?
(01:48):
That's actually quite impressive, the review mentioned
over 24 hours of continuous ECG recording on one charge. 24
hours. Wow.
Yeah. So you can get a full day and
night picture if needed, and it recharges in about 45 minutes
which is pretty quick. So that continuous data that's
not just during the workout then?
No, exactly. It's designed so you can monitor
continuously, and all this data feeds into an app and an online
(02:11):
dashboard, right? The software side.
Yeah. And the reviewer highlighted
that you get detailed ECG waveforms there, plus you can
generate PDF reports, proper reports to share with your
doctor. That's a big part of its value
proposition, that near medical grade output.
OK, sounds quite sophisticated. So the 5K runner liked it
overall, what were the main pros?
They called out what really impressed them.
(02:33):
Top of the list I think were thereal time alerts.
The strap can actually vibrate give you haptic feedback.
Vibrate. Why?
If it detects certain flagged heart events during your
workout, it's a direct safety feature, you know, for immediate
awareness. Whoa, OK, that sounds
potentially really important, especially if you're pushing
hard. Absolutely.
Then there's the full ECG tracking itself, being able to
(02:55):
record for 24 plus hours and easily share that detailed data,
maybe even live or as those PDFswe mentioned.
That's a big plus for proactive monitoring.
Makes sense. What about the sports side?
Is it accurate for training? Yes, the reviewer found the
heart rate accuracy was right upthere with the best, like the
Polar H10. So you're not sacrificing your
(03:15):
training data quality for the Health Monodome features?
So it really does manage both things well then.
It seems so, and they also highlighted some unique data
points that offers things like heart strain and a breath based
training load, stuff you don't typically find elsewhere.
Intriguing. We should definitely trickle
back to those. Compatibility was another
positive. It syncs with Apple Health,
(03:36):
Garmin Connect, Peloton, the usual suspects and the app,
well, maybe a bit busy, which we'll get to was seen as very
rich in data, lots of stats, trends and those Doctor Reddy
reports. So summing up the pros, the
potential to catch things a wrist device might miss, that
near medical grade aspect was seen as a major advantage.
(03:57):
OK, those are compelling positives, but no device is
perfect. What were the cons?
What did the reviewer flag as things to consider?
Well, the elephant in the room is probably the price.
It's around 321 or 428 dollars. Yeah, that's quite a bit more
than a standard HR strap. Definitely.
It's positioned as a premium device no doubt.
(04:18):
Another point, maybe minor for some, is the manual start.
You have to physically press thebutton on the pod before each
workout. You have to remember to do.
It exactly easy to forget if you're rushing.
The reviewer also mentioned the app layout.
While powerful, they felt it could be streamlined a bit,
maybe a bit cluttered initially.OK, a learning curve perhaps?
(04:39):
Possibly aesthetically they called the designer retro.
Maybe not the sleekest look, butthen again it's usually under
your shirt so perhaps not a hugedeal.
True function over form sometimes.
Right and FIC could be an issue for some people.
Getting that perfect consistent contact for both HR and ECG
might take some fiddling depending on your body shape.
(05:00):
That's common with chest straps though, isn't it?
It can be, yeah. And finally, a word of caution
on swimming. It has an IP67 rating, which is
water resistant, but the reviewer suggested it might not
be ideal for serious prolonged swimming.
May be OK for a splash, but perhaps not lapse.
Good to know. So practical points and that
significant cost, right? Let's get back to those unique
(05:23):
insights you mentioned. What are these data points that
really set the X2 apart? OK, one of the really
interesting ones is how it calculates training load.
Most devices just use heart rateright?
Yeah, maybe time and zones, things like that.
Well, the X2 also incorporates your breath rate into that
calculation, The reviewer noted this is pretty novel, but it's
backed by research. The idea is it gives a more
(05:45):
complete picture of your actual exertion level.
Breath rate? How does that help?
Well, think about it. Sometimes an activity might feel
really hard. Your breathing is heavy, but
maybe your heart rate hasn't fully caught up yet, or vice
versa. Looking at both gives a more
nuanced view of the physiological stress.
It provides a different angle onexertion.
(06:06):
That actually makes a lot of sense, especially for maybe
strength training or intervals. Could be, yeah.
Then there's body shock. This metric tracks mechanical
stress, kind of like how a stride pod measures impact for
runners. So looking at impact forces.
Exactly. It's about understanding the
mechanical load on your body, which could potentially help
identify injury risks down the line if you're consistently
(06:28):
overdoing the impact. Another layer of data.
OK. And the third one, heart stream,
that sounds serious. It's definitely leaning into the
medical side. It measures specific changes in
your ECG waveform, specifically the St segment.
That's coming. Getting technical now.
What's the St segment tell us? Basically, it relates to how the
(06:49):
heart muscle is repolarizing or sort of resetting after each
beat. Significant sustained shifts in
that segment, especially elevation, can be an indicator
that the heart muscle isn't getting enough oxygen.
Ischemia essentially. Whoa.
And the X2 tracks this during exercise.
Yes, and you can set alerts. The reviewer mentioned setting
one for a .3 millivolt shift. The idea is if you get that
(07:12):
alert during exercise, it's a strong signal to ease off to
reduce the intensity because it's a potential sign of strain.
It's quite different from just tracking pace or power.
That's a real time physiologicalwarning signal.
Precisely, It's moving beyond performance into monitoring the
heart's actual functional response under stress.
OK, this is fascinating tech, but how accurate is it?
(07:32):
Especially these more advanced metrics?
Did the reviewer test the reliability?
They did for standard sports HR,so just your heart rate during
exercise. They compared it directly with
the Polar H10 and a Garmin HRMPRO Plus.
Both known for accuracy. Exactly, and the X2 held its
own. The readings were consistently
aligned. They noted a few minor glitches,
(07:55):
but suspected that might have been due to the interference of
testing multiple straps simultaneously.
So for basic HR seems very reliable.
OK, good. What about HRV heart rate
variability? Lots of people track that for
recovery. That was a bit more nuanced when
compared against the Polar H10 using the HRV 4 training app,
the results weren't perfectly correlated.
(08:15):
Why might that be? The reviewer suggested it could
be down to differences in exactly when the readings are
taken or maybe set up sensitivities.
It wasn't bad, just not a perfect match.
They felt it was still functional for tracking your
trends over time, which is how most people use HRV anyway.
Right. Looking for changes rather than
absolute numbers makes sense. And the big one, the ECG itself,
(08:36):
how did they assess its accuracy?
Detecting arrhythmias and thingslike that?
Yeah. That's obviously hard for a
reviewer to personally verify without having a known condition
to test against, so they couldn't definitively say yes.
It caught my specific arrhythmia, but they did state
that the ECG data it produced looked legitimate.
The waveform seemed clean and detailed enough to be genuinely
(08:59):
useful if shared with the Doctorfor interpretation.
OK, so it looks like real ECG data, yes?
And here's a really crucial update that happened after that
review. In April 2025, the FDA actually
granted approval for the 4th Frontier X Plus, which uses the
same core technology as a prescription medical device.
Wait, FDA approved as a prescription device?
(09:22):
Yes. That's a huge validation.
It means regulatory bodies have assessed the technology and
deemed it accurate and reliable enough for medical use under a
doctor's guidance. That really bolsters the claims
about its accuracy. Wow.
OK. That FDA approval definitely
adds significant weight. So this brings us back to that
connection between this kind of tack and the science of exercise
(09:42):
and heart health. Exactly, and it's particularly
relevant when we look at the research around intense
endurance exercise and conditions like atrial
fibrillation or AF. Afib right?
I've heard there can be links. There can be.
It's complex though. Research like a review titled
Atrial Fibrillation AF in Endurance Athletes a Complicated
affair often describes a sort ofU-shaped curve.
(10:06):
U-shaped meaning. Meaning moderate exercise seems
to reduce your risk of AF, whichis great news for most active
people. But very intense prolonged
endurance exercise, especially over many years, particularly in
men, has been associated with a potentially increased risk of
developing AF. So too much of a good thing
potentially for this specific issue.
(10:27):
That's what some evidence suggests.
The research explores possible reasons.
Things like the hearts left atrium stretching or changing
structurally, shifts in the nervous systems, control over
the heart, maybe even some inflammation or scarring in the
heart tissue and some athletes. That sounds a little concerning
if you're a serious endurance athlete.
It's something to be aware of for sure, but it's crucial to
add context. The same studies often show that
(10:49):
even if endurance athletes have a higher incidence of AF, their
overall cardiovascular risk profile is usually much better
than sedentary people. OK.
So lower risk of stroke or otherheart problems overall.
And generally, yes, possibly because exercise helps control
other risk factors like blood pressure, cholesterol, weight,
(11:09):
and so on. It's a nuanced picture.
Right, not black and white. Not at all.
And this is where a device like the 4th Frontier X2 could
theoretically be very valuable with its real time alerts and
continuous ECG capability. It might offer a way to get
earlier warnings or detection ofevents like AF in this specific
population. So providing data that might
(11:30):
otherwise be missed. Potentially having that
detailed, continuous insight into how an athlete's heart is
responding to intense training could be really informative for
both the athlete and their doctor, especially since, as the
research points out, the standard risk scores doctors use
for stroke risk haven't really been validated specifically in
(11:50):
athletes, so more data could be helpful.
That really highlights the potential bridge between
performance tech and preventative health monitoring.
So pulling all this together, the review, the tech, the
science, who do you think this device is really for?
Who benefits most? Based on everything, I think a
few groups come to mind, Definitely active individuals,
(12:11):
maybe over 40, who are just generally more conscious about
heart health and want that extralayer of monitoring for Peace of
Mind. Yeah.
I can see that. Then you've got the you know,
the biohackers. People who love deep data, who
want ECG level insights into their workouts and daily
Physiology. Daily Enthusiasts.
Exactly. Also potentially people caring
for relatives with known heart conditions.
(12:32):
The monitoring and easy report sharing could be really
practical there. Good point having that data for
doctor visits. Right.
And more broadly, really anyone who is just actively heart
conscious. Maybe they're managing a
condition. Maybe they just want the most
detailed picture possible to discuss with their doctor and
make informed decisions. The X2 offers data beyond
typical trackers. So it's not just for the Super
(12:54):
elite athlete trying to optimiseperformance, but has wider
applications for health focused individuals too.
I think so, yes. It really seems to sit in that
interesting space between high end fitness tech and near
medical monitoring. OK, so as we wrap up this deep
dive on the 4th Frontier X2, what's the main takeaway
message? Well, I think the 4th Frontier
(13:15):
X2 really stands out as a uniquepiece of kit.
It seems to successfully blend that high accuracy sports
tracking we need for training with genuinely insightful near
medical grade ECG monitoring. A dual capability.
Exactly. Now you have to weigh that
against the significant price and maybe a couple of small
usability quirks like the manualstart or the app layout.
(13:36):
The trade-offs. Right.
But the potential upside? Getting that deeper, continuous
view of your heart's health, especially if you're active,
seems pretty substantial. It offers insights that most
other wearables just don't. So for listeners who are really
intrigued by understanding theirheart's response months in much
more detail during exercise and just daily life and who value
that kind of validated detailed data, the X2 could be a really
(14:00):
valuable tool. I think it could be, yes,
especially knowing that it's core ECG technology now has that
FDA approval backing its accuracy for medical use.
That adds a lot of credibility. Definitely.
It really makes you think doesn't.
It it does, and it leaves us with a final thought.
Perhaps as this wearable tech keeps getting smarter, keeps
giving us more and more detailedphysiological data, how is that
(14:22):
going to change things? How will this constant stream of
personal health information reshape how we understand the
long term impacts of exercise oflifestyle on our hearts and
bodies? And maybe more importantly, how
will it empower us as individuals to take more
proactive, informed steps towards preventative health?
The fascinating question it feels like we're just at the
beginning of seeing how this technology could really
(14:44):
transform personal health management.
Absolutely. It's a space that's evolving
incredibly quickly. Definitely one to watch.

practical there. Good point having that data for
doctor visits. Right.
And more broadly, really anyone who is just actively heart
conscious. Maybe they're managing a
condition. Maybe they just want the most
detailed picture possible to discuss with their doctor and
make informed decisions. The X2 offers data beyond
typical trackers. So it's not just for the Super
(12:54):
elite athlete trying to optimiseperformance, but has wider
applications for health focused individuals too.
I think so, yes. It really seems to sit in that
interesting space between high end fitness tech and near
medical monitoring. OK, so as we wrap up this deep
dive on the 4th Frontier X2, what's the main takeaway
message? Well, I think the 4th Frontier
(13:15):
X2 really stands out as a uniquepiece of kit.
It seems to successfully blend that high accuracy sports
tracking we need for training with genuinely insightful near
medical grade ECG monitoring. A dual capability.
Exactly. Now you have to weigh that
against the significant price and maybe a couple of small
usability quirks like the manualstart or the app layout.
(13:36):
The trade-offs. Right.
But the potential upside? Getting that deeper, continuous
view of your heart's health, especially if you're active,
seems pretty substantial. It offers insights that most
other wearables just don't. So for listeners who are really
intrigued by understanding theirheart's response months in much
more detail during exercise and just daily life and who value
that kind of validated detailed data, the X2 could be a really
(14:00):
valuable tool. I think it could be, yes,
especially knowing that it's core ECG technology now has that
FDA approval backing its accuracy for medical use.
That adds a lot of credibility. Definitely.
It really makes you think doesn't.
It it does, and it leaves us with a final thought.
Perhaps as this wearable tech keeps getting smarter, keeps
giving us more and more detailedphysiological data, how is that
(14:22):
going to change things? How will this constant stream of
personal health information reshape how we understand the
long term impacts of exercise oflifestyle on our hearts and
bodies? And maybe more importantly, how
will it empower us as individuals to take more
proactive, informed steps towards preventative health?
The fascinating question it feels like we're just at the
beginning of seeing how this technology could really
(14:44):
transform personal health management.
Absolutely. It's a space that's evolving
incredibly quickly. Definitely one to watch.
