Hi Genie!

Congratulations on starting a program. One piece of advice on the exercise bike -- work on your position. While the exercise bikes are a bit less adjustable than actual bikes a proper position helps avoid a lot of pain and makes the workout more effective.

Basically the rule is that if you put your heel on the pedal at the bottom of the pedal stroke you knee should be straight -- since both legs are a bit different, set this for your shorter leg. Next, the saddle should be far enough back that when the pedals are parrallel to the floor your knee should be directly over the ball of your foot. Finally, you pedal with the ball of the foot (not the arch) on the pedals.

Come spring, you might want to get an actual bicycle instead of that pool. It's a lot of fun out on the roads/trails/paths -- more fun than inside (I know as this is my Tour-de-Garage season).
