Sherry, why don’t you try resistance training using elastic tubing or light weights. You can still engage in endurance exercise but the emphasis should be on muscular endurance.
Muscular endurance training will transfer well when you get back on your feet.
Muscular endurance training involves training with light weights and high repetitions in the 12-25 range. This will also stave off muscle loss.
Can you engage in any core training? BTW core musculature are the muscles that run from your neck down to your glutes (front, back and sides.
As far as eating is concerned, I would encourage to take advantage of all the wonderful summer fruits and vegetables and limit your intake of processed food.
I wish you a speedy recovery! 8))
