Awesome! Thanks for all the help guys
So you guys were right. Swimming and road biking are out. Recumbent bike is in!
Stationary or spin bikes are a way better option for cardio.
You will be hard pressed to find enough road of an even grade without traffic or signals to get in a proper cardio workout in most areas, especially metro ones.
Also, i think a beard is mandatory for a recumbent, ymmv.
You may also be able to get away with a kickboard and some wrist/hand support for swimming to mix things up and the ellipticals etc still seem like viable options for you.
You can try some Kung fu stance training. I took KF years ago and they would put you in horse stance or some other stances for long periods. I'd be sweating like I was being sent to the chair just standing still.
