Instructables

The rowing machine is one of the less familiar fitness machines for cardiovascular training. Exercisers seem more likely to opt for the famous treadmill or the exercise bike. Nevertheless the rowing machine is as well and maybe even better than other fitness machines. On a rowing machine you strengthen your arms, legs, stomach, back and other muscles. In addition a rowing machine is less stressful on the joints and it can make a welcome change in your fitness program.

The total cost of this rowing machine is around  100 dollar. I didn't make this to save money, I just like to make my own.

Very cool. Wish I had the space in my dorm for one...
On another note, is there any possibility of getting this in some sort of CAD format?

It's seems that with a modification to the "frame", that you would be able to stand this unit up on end to save space when storing the unit..

Sorry, i didn't make any drawings.

Just finished building your rowing machine for my wife. She is quite happy with it.
It took a little while to convert from your metric to our silly english dimensions. Your pictures and directions were very helpful. A very clever and sturdy design.
Thanks!

Silly English dimensions? You thick twat.

that's a beautiful build, but this kind of rowing machine is cheap to buy. I have wanted a sesrious air-resistance maachine fora ges but can't afford a good one, and the cheaper versions just simply don't work. anyone know how an air resistance unit is made? what's in there? I am thinking that basing it around a bike wheel gives you an axle, bearings, a freewheel mechanism and opportunities to drive the wheel a bit like this project, or from a chainset. add air resistance fins and enclose in a perforated cylinder? it would take up more space than this.

great instructable! just thoght i should mention in the picture, your rowing wrong. the handle should be at the third rib from the bottom.
This is wonderful! I love rowing and was looking around for machines and none of them seemed good enough for the price they asked. This looks like a really fun project for me to bring that down, and still have a quality machine. Really appreciate the post!

And let me take this chance to introduce myself to the community - this will be my first project. Thanks to all those that make this site wonderful; it is everything I need for living on my own now :)

Very nice. It's just what I was waiting for. I'm trying to produce a sketch (using SketchUp) before starting construction, an I got a little confused with some dimensions. Is that possible that there are some mistakes regarding the location of 10 cm pieces on the base and the location of the vertical frame (120 cm)? Thanks for your answer.

Excellent build, looks like quality work. My only recommendation would be a back stop for the seat for newer rowers. I had a problem when I started (and still sometimes do) with whenever I sat down the seat always glided to the back and it was only because of the backstop that I didn't fall off. The bungee thing is also brilliant, the sound of the fan blades spinning up was always annoying at high resistance.

Amazing! Now we have some good competition for this contest! :) I'm sure you will win the Grand Prize, but I'm going for the first place! Great job again, and good luck!

Very probably one of the most well written, and detailed Instructables I've seen since being exposed to the site. Fantastic work, sir! This just made it to my list of projects!

That's a great looking rowing machine, it's probably not economically convenient to make your own, but I bet it's all compensated by the satisfaction of such a beautiful DIY final result.
HHarry (author)  BeFit3 years ago
Precisely!

Wow. really great write up and machine!
HHarry (author)  Nick.D3 years ago
Thanks, for me writing was the hardest part.
Very nice job. Another advantage of bungee-power over pneumatic resistance is that bungees are always quiet. They do not screech when they wear out and are cheap to replace. This is going on my eventual projects list - I lost my rowing machine during the last move.

Thanks, it was pretty easy to make to. The only thing I would recommend: if you're used to exercising on a rowing machine, use thicker bungees.
This is just awesome! Very nice build.

That's awesome. My back and legs are tired just looking at it. Excellent work!
