Cardio Equipment on Board

[Katiusha]

Does anyone carry dedicated cardio equipment on board for use while on passages? If so, what kind and what make? Do you find it reliable in salt air?

I've been taking the dinghy ashore and running, using gyms at the marinas, swimming, biking, etc. But it would be nice to have something on board...

We don't have enough space for a full-blown treadmill (also running while on the ocean might not be wise) or an elliptical. So I was thinking a foldable mechanical stairmaster, rowing machine, or installing mounts for my bike. The last one is the easiest, but I don't really like bicycling for cardio. Not sure what other compact cardio equipment is there...

How do you deal with doing enough cardio during passages? During rough weather you don't need any other exercise, but for those trade wind passages...

Thanks in advance
