How can I train for endurance if I’m often at sea?

I'm working on a ship in crowded conditions for months on end. I want to go hiking and trekking on my time off. What's the best way to maintain endurance without being able to walk or run at sea? Bonus if I can do it in 30 foot swells.

First, recognize what you have. Are there stairs on the ship? Do you have some exercise equipment? Is there a track around the outside of the ship? Take a look around to see what’s available. Even if it’s just you in a room, you can still use your bodyweight to perform challenging circuits, including skipping, marching in place and jumping rope.

Think of this as an opportunity to change your routine and focus on the basics. Ask yourself which exercises you can modify to do in place, such as lunges. List all the moves you can think of and create a bodyweight circuit. After your circuit, hit the stairs for at least five minutes.
