Injury set-back

leefudge7

Hi all . I have been using My Fitness Pal for a while now, and find it a great way to keep track of my diet and exercise. But a couple of weeks ago, I slipped and fell on my right knee, resulting in surgery and now having to wear a splint for 4-6 weeks. So I am being very careful with my food choices. But I'm concerned that I can't go to the gym , or anywhere actually, because I can't bend my right leg. I would appreciate some advice on what exercise I can do at home.
