fitness on a sail boat

[leahangel777]

im 46 and living in a 38 ft monohull sloop
sailboat
when the weather is good i can walk or jog the beaches
or do yoga on the deck

but how can i keep the exercise up in a confined place ??
it drives me nuts to be cooped up in a small area for a long period

can you suggest some exercises for the therabands i have those
and about 2 feet of space to work in
in the cabin

thanks
