Hi Gaye,
I can tell you what worked for me. I had simultaneous bilateral THR in May '05. DH and I are fitness enthusiasts and are very athletic although my hips were starting to slow me down. I had been doing plenty of PT to try to help with the pain, but finally surgery was the only option. I had 2 months from the time I found out I needed surgery to the date of surgery. I cut way back on cardio and stretching and really hit the weights hard. I worked on my whole body:core, upper and lower. As a result I went into my surgery as strong as I have ever been in my life. The hard work paid back big time. I was able to come home in 2 days (a hospital record), never used a walker and was forgetting to use my crutches in 4 days when I went room to room. My PT was just ticked pink and would bring her colleagues to check me out. The home health nurse they sent to me was less enthusiastic, in fact horrified at what I was already doing, but after she called my surgeon several times to "tell on me" he told her I was fine and probably didn't need her anymore.
I worked hard to get in such good shape, but I would do it again in a heartbeat if I need surgery again. If you are not familiar with weight training, I would hire a personal trainer to get you started. It can really help. And of course, maintain a positive attitude about your surgery, you are about to get your life back!
