Back / ab strengthening while bedbound?
I have to lay in the hospital for a few months. I can lay flat, roll to either side and move my lower limbs as long as they aren't both lifted off the bed. But I'm not supposed to put heavy strain on my abdominal wall muscles - i.e. no crunches or sit ups, no twists, no Pilates type stuff.
How can I exercise my back muscles and prevent my abs from turning into jello without straining the abdomen? Is it physically impossible? It is important that i keep my tone because I will need abdominal surgery later on, and being weak is going to prolong recovery.
I am seriously atrophying here and PT didn't suggest anything. I have a monitor at all times so I would know if I am straining too hard.
