Concept2 Forum

One user particularly likes to row at vigorous intensity for a minute or so, clocking 1700-1800 Cal/hour, without any regard to technique. His body, his choice. Want to know if such intensity be bad for any machine parts.

Thanks

Nah, you can pull close to 1 min splits and nothings happens. Which is way beyond 1700/1800 cal

Erhh... that is a pace around 1:33 minutes/500 meter, equal to less than 440 watt.

Your other users are so slow, that this appears extraordinary to you?

Some people are above 1000 watt on these machines. 440 watt is nothing.

Going by the C2 calculators, that's an average of 1338Watts - he likely peaked higher.

No way is any human going to break a Concept2 - they're massively overbuilt.

Yes the Concept 2 rower can handle it but only IF it is well maintained.

The one way or clutch bearing in the flywheel needs a bit of lube every few years and all the fasteners that hold the front leg in particular needs to be checked for anything loose.

The crud needs to be kept off the slide and the seat rollers cleaned.

Seen plenty of these Ergs totally destroyed in the Gym environment where nobody ever does any maintenance on them.

I think it is way more than 440 Watt. Calculation below.
1700 Cal/hour = 1700*4184 Joules/hour = 7112800 Joules/hour = 7112800 Joules/3600 sec = 1975 Joules/Second = 1975 Watts
Am I doing something wrong here?

But from your reply and others as well, I get it, that the capacity is way more than any kind of failure at 1700-1800 Cal/hour.

Thanks

The pm does cal differently, you get cals for free. I believe 300. So 1700 on the pm is 1400 on the handle. Set the pm on watt to see that number.

Probably 1700Cal/hour refers to the energy consumption in the human body. Because the human body has an efficiency between 25 and 35% only that fraction is going into the rowing machine. The rest is turned into heat. So 1700 Cal/hour is around 400 watts to the C2.

Yes, you are doing something wrong. Very wrong, actually: You are setting the efficiency of the human body to 100%.

C2 sets the efficiency of the human body to 25%. And then they slap on another 300 kcal/hour to cover the muscle work, which is not getting into the handle.

What...... the...... actual..... heck???? That dood is crazy beef cake! He looked WAY too big for that machine! That was nuts to see!
