Ruptured but recovering

So, being from the South, I love to eat.  I won’t diet too much but shy away from too many sodas and chips and candies.  What does everyone do to stay fit?  I called the doc to see if I can swim but i’ve yet to hear back.  Any suggestions?  Who’s got Achilles-in-boot workout plans? 

I do some weights and machines, but I need cardio back!

So, after 2 weeks in a splint followed by 2 in a hard cast i am in my boot now.  Oh what a feeling!  Due to the need for me to make some money (bills and such) I have decided to drive.  I am extra carefull and use my left to brake.  I take the boot off and put a sandal on to drive.  I try to bend more at the knee than use my ankle and pronate.  Hopefully I am not doing any damage.  Any thoughts?
