Post-OP boredom

Hello everyone out there, this isn't less blog but more a question. I'm a very active woman and I'm missing doing any kind of sports. I'm in the fifth week since my OP now and I feel getting that itch more and more. I need to do some workout. I can't do the usual stuff I do, since those are sports which would not be advisable to do so soon after that surgery, like cycling, sports climbing, inline skating or diving.
But I also need to do some less strenous sports to get back into shape again and getting my fitness back. I can't just lounge around.
I'm sure I'm not the only active woman being post op here, so maybe you have ideas or an advice what I could do while recuperating?
