Essentially what rndmguy said, but I am going to add on. Can you swim? I imagine that it would be a fairly low intensity exercise, but still be enough to get you fit. Also, try squats while you are in the water to strength train. Aqua-aerobics are often prescribed to those who normally have issues like that.
