For over all core fitness and increased stamina and aerobic workout without putting pressures on older joints as mentioned above . You cannot get better than swimming.
You need to get the heart rate up and keep it steady 45 mins to 1 hour is good
Clearly if your younger fitter then other exercises are there
Also yoga to help stiff ligaments and muscles move
On long trips I have exercise bands that can go around the mast or many other variations to get a full work out.
Half an hour strong swimming is quite tiring, I would target that if you are not a regular swimmer. Also some pools' Covid restrictions mean you can only book half hour sessions.
