Re: Max heart rate

Has anyone done enough work with HR Zone training to experience whether the %MHR or %HRR is a better indicator of the aerobic threshold and anaerobic threshold, etc? I think not. There is a lot of literature, mostly with elite athletes, showing that tons of intermediate intensity is not great, and ...

Re: Investigating Race Starts

Yeah, that's why I was nowhere near RowPro or any proper race software for these tests. And the flipside to what you're saying is the people who time their first stroke just enough before the start that they don't miss the start at all, but not to much that it's a false start. It was really interes...

Re: Investigating Race Starts

My understanding is that the PMx monitor underestimates the power of your first several strokes, because it uses some default parameters for drag. So in trying to optimize your performance, you are actually trying to do two things, which may be incompatible: maximize your actual energy output, and m...

Re: Problem with my Rowing Machine

Here's a thread discussing the issue: https://www.c2forum.com/viewtopic.php?f=10&t=205309 Bottom line: The clutch is press fit into the flywheel, and it can be replaced with effort, but Concept2 will sell you a new flywheel assembly for $90. Before you do either, remove the flywheel assembly, clean ...

Re: What do you lube your chain with

I don't think WD40 is a good idea, because it evaporates quickly. Concept 2 recommend (and sell) 3-in-1 oil. They also say that motor oil or mineral oil will work. When I got my Model D in 2003 they supplied "Concept 2" chain oil, which I still have some of. When I got my wife's Model D in 2013 they...

Re: PM5 Workout Deletion

I'm a little late to the party, but the Concept 2 Utility lets you delete all workouts, or all workouts prior to a particular date. It also lets you bulk copy them to a computer file.

Concept 2 Utility is free ... you need a USB printer cable and a laptop to use it.

Re: Most Beneficial Rowing Workouts for a Runner

I have only anecdotal evidence re: crossover. I used running and rowing interchangeably when training for 10km run (PB 39:55) and marathon (PB 3:39). So I'm hardly elite. But I found the rower comparable to a run of the same time & distance.

Re: New ErgData issue

I got the exact same issue! It works if I do “just row” but any set distance causes some hard error screen crash. It’s not the firmware - mine is up to date. It’s the stupid app change which wasn’t needed. Was perfectly happy with the old one. You can still get the old one. Check out "ergdata for P...

Re: Trying to understand drag factor better

I totally agree that "longer oar" ("taller gear" on a bikeERG) is a better analogy than "heavier boat." I didn't know about the Model D magnet. That's the magneto that charges the battery? I guess I what I didn't know is that Model C didn't have one. How does it sense angular velocity? But I have a ...

Re: Trying to understand drag factor better

dragforce is determined by a constant x velocity. Inconsistency in that system, or many variation in speed, is very ineffective. To be pedantic, drag is not proportional (i.e. constant x) velocity. It is proportional to some power of velocity, and I think C2 uses square as the power, but I'd have t...

Re: Trying to understand drag factor better

The angular mass of the flywheel is fixed, as is the gear ratio. So on your initial pull from stationary, it will feel equally heavy with equally long oars regardless of your damper setting. Only as speed increases will the damper setting have effect. Unfortunatly, your interpretation is incorrect....

I think the jostling from walking helps. I think the name comes from farmers carrying toolboxes.
On reflection, I think the name might come from carrying buckets of water or feed. Same idea.
