How to prepare for a cruise ship gym

Prepare for a cruise ship gym. ost ships have a gym or health center complete with exercise machines and weights. Many people use the "promenade" deck – which usually loops around the ship around mid-decks – for walking or jogging. Some ships find room for a putting green, golf simulator, or a basketball or tennis court (enclosed by ball-catching nets) on deck. Recently some new ships have been built with an ice rink, a rock climbing wall, or a "surf park".
