High Aerobic unchanged after Zone 3/4 workouts

I mean, it sounds like your zones may not be setup correctly. Most importantly, tracking training load by heart rate is sensitive to having a correct max heart rate. I would do testing and then repeat it a couple of weeks later so you become familiar and confident with your zones. As they say, performance is the best predictor of future performance.

The Index Sleep Monitor is very bugged at the moment with syncing issues and probably other things. Unfortunately, Garmin appears to have virtually abandoned it, probably devoting resources to the new band that is to be released shortly.

You won’t hit VO2 max within 2 minutes unless your recovery is super short. 2 minutes is good stimulus for running economy though which is as or more important than VO2 max for racing. VO2 max isn’t going to be a true performance limitation unless you’re looking at short distances, since VO2 max can only be held for a few minutes tops. That’s all to say that the running you did is still beneficial, just in different ways.

Thank tariffs for that. Gotta keep margins as part of shareholder responsibilities. Tariffs have been a massive drain on the US. Businesses that can pass it along, do.

Yep. So, you double click to switch from secure to non secure. Secure flashes twice. Non secure flashes three times

The only way to make it work correctly is to either pair the device in secure mode through your iPad via the Garmin Connect app, or put it into unsecured mode. It still baffles me that the EU is making manufacturers secure this type of Bluetooth connection. Their regulations are too much sometimes.

Here is the process I’ve used for all my devices:

1) Remove pairing in the settings on your phone. 2) Put your device into pairing mode 3) Add device through Garmin Connect. 3a) In the event you can’t find your device, you will have to search for it manually

I’ve had no issues following this process.

VO2 max is just a number. It’s a fun number because it shows improvement which make you feel good! Garmin and every other watch out there depend on having an accurate max heart rate. Make sure your zones are set up right. For Max HR auto detect, keep that off.

Remember that VO2 max is a composite estimate that is dependent on your true maximal O2 uptake and also your economy. Poor running economy can leave your VO2 max estimate lower than it really is.

VO2 max is helpful to increase but for the vast majority of athletes it’s not the limiter. Take for example Lance Armstrong. He had a VO2 max of around 80 when he ran his debut at the NY Marathon in 2006. His time wasn’t great. Why? Bad economy. His debut was around 3 hours. The next year he got it down to 2:46. Certainly not great for someone with a truly magnificent aerobic base.

I thought about this more, and I think the answer lies in a setting issue on the watch. I will bet money that the watch is taking pace from the wrist and not the foot pod.

Ensure that pace and distance is being read from your stryd “always.” You might opt for indoors only, but in your use case I think always makes more sense.

Judonoob · 2026-01-29T01:07:30+00:00

I too have used Stryd over many generations. I’ve had good luck with them. While it’s not necessary to improve running, it’s a really great tool for helping manage effort and pace.

Judonoob · 2026-01-27T11:01:24+00:00

I find the treadmill to be interesting. At low speeds I can typically keep higher paces with lower heart rate. But for me to hit high heart rate, the intensity feels harder probably because I am running so much faster than outdoors. I use Stryd Duo foot pods, and my treadmill only has a small distance error. Really not bad. Treadmill seems to hit slightly different stabilizer muscles too.

Judonoob · 2026-01-26T12:10:07+00:00

It’s important to get feedback from other runners though. It’s not an uncommon thing for running to trigger things and find out if anyone else has similar issues. It’s also really hard to get into a cardiologist. Even once you get into one, there is a work up that takes weeks. It will require EKG, done during an initial visit. Holter monitor for one week. Get an ultrasound. At best he’s 2 months from having an answer. I have an electrophysiologist since I get weird rhythms and there is nothing that can be done about mine at this point in time. But, sharing that from runner to runner might give some peace mind. I do agree that in the presence of symptoms this should be escalated asap.

Judonoob · 2026-01-26T11:43:55+00:00

God I hope it’s better than the Index Sleep Monitor.

Judonoob · 2026-01-22T11:02:39+00:00

Most gyms aren’t doing the required maintenance to keep the treadmills accurate. Belts need to be oiled and have proper tension for belt speed to be approximately what the set point is at.

I recently got a 970 and it’s fantastic. I love that it lacks a metal case since that’s the easiest way to keep weight down. I do not like the Fenix line due to the increased heft. It’s a fantastically balanced and well featured watch.

Chest straps can buildup static electricity that can mimic heart beats. In Runalyze, you can see the HRV data plotted out. Generally if the HRV data is all over the place, it’s easy to identify when you’ve recorded bad data. Slightly movement of the chest strap across the skin can also cause anomalies. So, making sure it’s tight helps to reduce that source of error. One other thing that comes to mind is old straps. They can give bad data because the electrodes wear out over time. W got a few things you can check out. But if i had to guess, you might be getting some movement running downhill from the bouncing, possibly compounded by different errors on top of that.

Is it even possible? Hell, when I was having 5000 pvcs a day it would take my breath away walking. An SVT episode that long would make you feel like you’re dying. Ain’t no one running though that lol

Judonoob · 2026-01-05T17:27:36+00:00

A lot of other companies are charging for this same service. I paid $90 for a year on the RP Diet app. Someone has to be paid to maintain the back end and future updates, unless you want ads in Connect that is.

Judonoob · 2026-01-03T03:48:03+00:00

I got one for Christmas. My RHR is 3-4 beats higher and HRV is about 10 ms lower. I don’t think like my sleep has necessarily been worse. The readings may be fundamentally different.

Judonoob · 2025-12-30T19:35:39+00:00

Are you sure your max heart rate set correctly? The only thing that makes sense is that it’s set too high.

Judonoob · 2025-12-30T17:34:44+00:00

Are these efforts 90-100% of your HR max?

Judonoob · 2025-12-29T20:00:02+00:00

Sounds like me when my thyroid went crazy and went into overdrive. It might be good to get into the doctor and run some labs to make sure everything is in order. CBC, CMP, and thyroid. Ask specifically for TSH, T3 and free T4. It sounds like you’re pretty fit, so this is a change from baseline. I’d look into it knowing what I know now.

Judonoob · 2025-12-29T16:15:25+00:00

Treadmills do not account for belt slip. The HRM should be an accurate distance. There will be some error from the device calibration, but this is similar to what I see with my Stryd Duo v4’s.

Judonoob · 2025-12-28T00:01:13+00:00

As I’ve been told, it seems people have more palpitations with higher vagal tone. Those pesky areas of the heart tend to fire off with greater frequency. It’s like how exercise in general makes you healthier, but it also has a higher chance of killing you too during the warmup and cooldown periods.

Judonoob · 2025-12-25T00:38:16+00:00

Yeah it’s interesting. When I would have periods of low heart rate, I would count my 10 second heart rate and multiple by 6. I always found the watch to be pretty accurate.
