I’ll chip in here since I have been rowing for years. I can’t claim expertise, just experience. I’m also interested in learning from thinhorn and others.
I come from a rowing family, but I was an endurance runner (too small for an oarsman). Just like running, you have to vary the time, pace, and intensity if you want to get better.
My exercise budget is one hour calisthenics, weights, and high intensity cardio, with at least one hour of hiking/walking. I am currently 47, 5’10”, 187. Goal is to be 5’10, 172 by age 49.
I personally do Peloton workouts using the app and a thing that holds my phone on top of my Concept2. I find it easier to push myself with a cute Asian or pretty English girl telling me what to do.
Sunday - no rowing (long hike day)
Milestone Monday - 5000 for time (goal of Tabata Tuesday - 20 minutes Tabata
Wild Wednesday - 20 minutes HIIT
Thirty for Thursday - 30 minutes endurance
Friday ends in Five - 15 minutes HIIT
Satisfying Saturday - 20 minutes easy row
I’m considering making Friday an even longer row (Forty for Friday). I need to see how my body responds over time to what I’m currently doing.
These are shifting numbers (they should get better over time), but my paces are currently:
Resting - 2:15 to 2:20 per 500
Easy - 2:11 to 2:15 per 500
Moderate - 2:07 to 2:11 per 500
Challenging - 2:03 to 2:07 per 500
Max - 1:57 to 2:01 per 500
My goal is to get my moderate to around 2:00 per 500 with the other paces roughly 10 seconds faster or slower per level. Prior to breaking my leg, my Moderate was 2:05 and my Max was 1:45 to 1:50.
Edit - my memory is apparently garbage, so here are some pictures from my morning workout. I am pretty happy with this performance (bearing in mind I did 25 minutes of calisthenics and weights beforehand).
There was an interruption a couple of minutes into the row this morning and I had to pause for one minute.
