Not like we do, but through their day to day activities they get all the exercise that they would need.
They produce lots of blubber to protect themselves from the cold and the extreme pressure at lower depths. Jellyfish drift, whales swim. This is partially true but the main reason whales have a lot of blubber is a question of buoyancy. Fat is much less dense than muscle and bone and without it the whales would sink very fast.
