Finish screen for today’s 5000 meter rowing session.
Today’s aerobic workouts consisted of first doing 5K on the rowing machine. The 5K was wrapped around three intervals of 500 meters each, like yesterday’s rowing 5K. It was RPE Level 4.
After the rowing, I did six intervals of 500 meters each, on the SkiErg. The target pace for each of the 500 meter intervals was going to be 2:10 to 2:11, but after the first interval at target pace, I faded during the second interval and went a lot slower during the final 5 of 6 intervals. The SkiErg session was RPE Level 10 for sweating but RPE Level 7 for breathing.

Today’s Morning Readiness reading,Last night’s sleep was fairly good quality, 5 hours 35 minutes.
Last night’s sleep had a long interruption of about 90 minutes but total time was sufficient at 8 hours 45 mins.
Today’s main session was a 10K done at RPE Level 2. There were 8 additional, shorter sessions. A screen recording was made for row-along. The screen recording is here: Indoor Rowing 10K 583 Calories 01312019

There was a wide-awake-in-the night sleep interruption, but I was able to get back to sleep, sleep in late and make up for accumulated sleep debt with 9 hours 5 minutes sleep.
Today’s workout started as a speculative half marathon rowing session. After 30 minutes I decided that 40 minutes would be enough. The session was done at RPE Level 3 but if the entire half marathon had been done, it might have been a level 4 or 5 by the finish. It was preceded by a SkiErg warm up and followed by 109 Calories on the SkiErg.

This is a graph of this morning’s heart rate samples, taken every few minutes by the Apple Watch. You can see that at about 5 AM heart rate spiked a bit and stayed elevated from 5 AM until this screenshot was taken at about 9 AM. HR returned to normal sometime before noon.
There is no HRV analysis reading for this morning because I was having a bit of Afib at the time the HRV reading should have been taken. Afib during an HRV reading skews the reading and basically makes it worthless. So the EliteHRV app was skipped for today and instead I savored and drank black coffee.
The Afib started early this morning after I woke for a bathroom call at about 0500 and returned to bed. So… rather than lay awake, I got up. Sleep had been good until then but total sleep was a little short, at 5 hours 50 minutes.
Sleep was good and without interruptions from about 11 PM to 5 AM.
I felt okay, so I assumed the HRV reading would have been a “GO” for doing any workout. The goal for today’s aerobic activity was to burn 800 calories. The goal was reached with 3 sessions on the SkiErg and one on the rowing machine.
From first to last they were (1st): A 99 calorie warmup on SkiErg at RPE Level 3, (2nd): 1K on SkiErg at RPE Level 5 (3rd): 2K on SkiErg at RPE Level 6, (4th) 540 calories in 8,995 meters on rowing machine at RPE Level 5.

Today’s workout consisted of 5,027 meters on the SkiErg followed by 5,027 meters on the rowing machine. All done indoors, of course.
Today’s EliteHRV Morning Readiness reading was okay for any workout, though the HRV score wasn’t as high as yesterday’s.
The day began with a green light from EliteHRV (see above) and a good night’s rest of 7 hours 40 minutes (see below)
The first of the two workout sessions was set up to be 10K on the SkiErg. That’s what yesterday’s SkiErg session was supposed to be also, but I quit that one yesterday after about 2 miles. Today I got further with it and quit today’s 10K on the SkiErg after a little over 3 miles, logging 5,027 meters.
So for today’s rowing session, I set the rowing machine for the exact same distance, 5,027 meters to compare results. You can see from the session reports that I went a lot faster, with a lower heart rate, rowing than SkiErg-ing.

This morning’s EliteHRV readiness reading was good, but the most remarkable thing was the HRV score of 54. This was the first time HRV score has ever been higher than mid 40s.
Last night’s sleep was interrupted by a long stretch of insomnia from about 2:30 to about 5:00 AM. One thing I did during that insomnia was to resort to an emWave2 device and breathe following its breath pacer, which resulted in a longest-ever “meditation” of 36 minutes in a state of “coherence”. I wonder if that was a factor in getting the higher-than-ever HRV reading with EliteHRV today?
Today’s main indoor rowing session was indoor skiing on a Concept 2 SkiErg. I connected it to RowPro for the sake of logging it and getting a bigger screen display of data. Since RowPro is only designed with rowing machines = boat avatars in mind, it looked like I was rowing a boat on the digital river. Something was going on with the stroke rate not translating well to the display and instead of displaying what should have been a stroke rate in the 20s or 30s, it was all over the place and very frequently displaying a false stroke rate of over 100 SPM. But the other data looked okay.
I preset the distance to 10,000 meters on the SkiErg, but by the time I reached between 2K and 3K I was breathing hard and sweating profusely, though my average pace was a mere 3:00 minutes/500m. So I guess it will take a lot of getting used to as an unfamiliar workout for my underused upper body.
Instead of going the full distance of 10K, I stopped skiing after about 2 miles, which was 3,250 meters. Since I’m brand new to the SkiErg, I started out with the lowest possible damper setting at 0 (zero) and that was a Drag Factor of about 51 according to the PM5.
I rated both the SkiErg 3250 meters and the rowing machine 1,000 meters as each RPE 5.
After the shortened session on the SkiErg I switched to the familiar Concept 2 Model D and rowed 1,000 meters plus a 750 meter warm down.
This morning’s EliteHRV Readiness reading was optimal for any kind of rowing…
Today began with a good HRV reading, so there were no restrictions regarding rowing. Also, it followed a good night’s sleep, which was another plus.
Seven hours and forty minutes of good quality sleep last night.
Today’s indoor rowing consisted of two sessions. First, a one minute session which was done just for the sake of putting anything in the rankings for the 1 minute sprint category. Second, was a longer session of 8,224 meters, which was done just for the sake of logging more calories for a current Concept 2 challenge.
The one minute session was preceded by a 750 meter warmup and followed by a 750 meter warm down. The one minute sprint was done with a target pace that would rank me at about the lower 25% of those who had ranked 1 minute sessions to date. That was a pace target of about 1:49/500 meters. I didn’t want to row any faster than that, because the warm up was too short and I wouldn’t really be warmed up enough for an all-out 60 second sprint.
After the one minute sprint was finished, I did an easy 750 meter warm down and that is when the “heart strangeness” happened. It felt like a bit of fluttering and heart rate spiked and remained higher than it should have been for the easy warm down pace. Another strange thing about that strange heart rate behavior during the warm down was that when it spiked, it spiked up to 150 BPM, which is exactly as high as heart rate managed to climb, before the ultra-short 1 minute sprint was finished. Was that a coincidence? Or was that the heart’s way of saying it wanted to sprint for longer than one minute? One minute wasn’t enough indulgence in sprinting? The heart is eager, and “rarin’ to go” racing?
That “strangeness” happened in uncharted territory, because the warm down was tacked on to the 1 minute RowPro session and RowPro does not include tacked-on warmups or warm downs in its charts for the main session report. Below is a screenshot of what heart rate looked like when it spiked during the warm down.
Heart rate had been in the mid- to low-120s during the warmdown, until abour 426 meters remaining, when it spiked up to 150 even though rowing effort remained at a constant, easy level.
A screen recording was made of the entire 1 minute session including its warmup and warm down, so if you view the screen recording, you can see how it acted in real-time on the RowPro screen. The one minute session screen recording is here: Indoor Rowing 1 minute sprint 01122019
For those of you who’d like to row-along with it, a screen recording was also made of the 8,224 meter session and it is available at this link: Indoor rowing 8224 meters 01122019
After the warm down following the 1 minute sprint, I thought I’d have to stop rowing for the rest of the day, but within a few minutes the Afib went away and heart behavior returned to normal, so I did the 8224 meter session in order to bring the day’s total to 10,000 meters and burn a few more calories.

On the brink of death or what? This morning was the worst reading I’ve ever had.
Yes, this morning’s EliteHRV reading was the WORST EVER reading since I’ve been taking the daily Morning Readiness reading. But I ended up discarding it, because though my actual HRV reading might have been poor, it also might have been good… the results were skewed and basically worthless because there were too many data glitches. See additional screenshot below, for what EliteHRV said about today’s reading.
The “artifacts” were due to the fact that I was having a little bout of heart flutter AKA atrial fibrillation.
I got plenty of sleep last night, at 8 hours and 20 minutes. But you can see that heart rate was elevated from about 5:30 AM through the entire remaining time of last night’s sleep – that’s when the heart fluttering happened.
Other than the fluttering heart, I felt okay. It stopped fluttering around midday and I decided to row late in the afternoon, at a moderate pace.
Today’s rowing session was 17,000 meters done for the sake of burning calories. The hope was to burn at least 1,000 calories and that goal was almost reached, with a total of 988 or 989 calories. (The finish screen reported 988 calories and the report says 989 calories).

Today’s Readiness was taking with a grain of salt as I mentioned in yesterday’s post… but the grain of salt was later dispensed with after I received more knowledge about the app from a reliable expert on the matter.
There was no indoor rowing goal at the start of the day, except to do some rowing before eating anything. The goal of burning more than 1,000 calories rowing today was decided upon after rowing a 60 minute session, warming down, looking at the total calorie count and noticing it was less than 1,000. One of the current Concept 2 challenges is called “The Big Burn”. The object of that challenge is to burn at least 20,000 calories on a C2 machine this January.
This morning a friend explained how to easily check to see whether or not the EliteHRV app had detected any “signal artifacts” during its morning reading. If it has detected any artifacts, the reliability of its reading is in question, according to his analysis. Checking simply involves clicking/touching a few particular places on the app, but I had been unaware of that.
The happy news was that there were no artifacts and the morning readiness reading today is worthwhile as a training signal.
Another important training signal, quantity of sleep, was also “GO” for training today, at more than 8 hours sleep.
Resting heart rate was a little high at 55 BPM. That was not a drastic difference from normal and was probably due to the virus that tried to get a foothold the previous day. So I took the RHR as a “GO” training signal also.
There is another possible training signal that I don’t know what to think of yet, so I guess I’ll just have to keep watch on it from day to day to form an opinion. It is a relatively new data feature of the sleep logging app I use (SleepWatch): Average heart rate during sleep. It seems to me that average sleeping heart rate would be influenced by things like how much a person ate before bedtime, how much time passed after eating and before going to bed and room temperature, to name a few things that come to mind. I don’t know if it is as relevant as RHR or relevant at all, as any kind of a training guide or signal.
There is a screen recording of the main piece, a 60 minute rowing session today. For those of you who’d like to row along with it, the link for the screen recording can be found here: Indoor Rowing 60 minutes 01052019
Screenshots for the 60 minute piece are below. It was done at about RPE Level 5. The other two shorter shorter pieces were done at RPE Level 1 and I won’t bother posting anything about them. But they are visible to anyone who has a Concept 2 logbook account and who is logged in to the online logbook.
I didn’t get a very early start today and my legs felt a bit tired, so I put off rowing until after noon. For the sake of getting more critical repair and replacement work on my mitochondria, especially the heart mitochondria, I also put off eating until after rowing was finished. So the time before breaking fast was more than 20 hours, which was a solid 8 hours of special benefit to the mitochondria. Happily, both heart rate & rhythm behaved perfectly.
Today’s EliteHRV Morning Readiness reading allowed for any distance or effort level.
Today’s rowing was mainly for the purpose of catching up on more of the “lost meters” this season. Last season my daily average meters was more than 10K. So far this season the daily average is a little over 5K, so I have a lot of catching up to do between now and the end of the season (April 30th).
More than enough sleep (8 hours 40 minutes) last night contributed to today’s favorable EliteHRV reading.
We got a late start this morning, so there wasn’t as much time for rowing as hoped. The two main indicators I use to tell me if its okay to row hard and/or long distance were both favorable. Those indicators are the EliteHRV Morning Readiness reading and whether I got sufficient sleep. The one that I currently give the most weight to is the EliteHRV Morning Readiness reading.
Since both indicators were “GO FOR IT!” I rowed 24,000 meters. None of it was hard rowing but the distance was sufficient that I feel relaxed for sleep this evening.
The four sessions rowed today were, in chronological order: (1st) 2K distance for warmup, (2nd) 10K online with two other guys, at an easy “overdistance” pace (which in this case meant a pace that would raise HR to no more than 55% to 70% of maximum). After the online 10K, there was a (3rd) 10 minute warm down which was 2,000 meters. Later in the afternoon, I decided to do (4th) another 10K and the plan was to do 2 or 3 intervals of 500 meters each and a final interval of 1,000 meters, with the pace of each interval at about 2:00/500m.
A view of the Concept2 online logbook showing the listing of today’s 4 rowing sessions.
But the heart acted up in its strange fashion and became too irregular to register a heart rate for a lot of the time. When it was registering a heart rate, HR was way too high and once got as high as 230 on the RowPro readout from the Polar heart strap. The Apple watch activity tracker, a separate heart rate logging device, showed high heart rate also. So, after a couple of 500 meter intervals at about the target pace of 2:00/500m, I slowed down for the remainder of the 10K. The main goal of completing the distance was achieved. Immediately below this paragraph is a screenshot of data for stroke number 888 through 918 of the strange-hearted 10K.
Strokes 903 through 913 are the highest heart rate I’ve ever seen displayed when my heart acts strangely.
