Getting Back Into Shape

Hi All...I read on occasion but don't post too much. Do have a question tho and could really use some advice. In June I broke my leg on a shallow beach break. It was a pretty nasty fracture (tib and fib) and required two surgeries to fix. Long story short, its been over 6 months since I have been in the water and now that I am finally cleared medically to surf, I am well aware of the fact that my fitness level not where it needs to be. My goal is to be back surfing by spring and I was wondering if anyone had any experience / suggestions for getting back into 'surfing shape' after a long layoff. I figure I have about 12 weeks to make it all happen. I know I need cardio because I have gained some weight. I also plan to pick back up a strength training routine, which I did pretty regularly before I got hurt. I'd really like to work in some balance and cross-stepping training, but not sure what really works and what doesn't. I have a Bosu ball, but have never really used it for anything other than crunches. I like a diverse fitness routine, so I am open to any and all suggestions.
On an unrelated topic, just finalized plans with my shaper for a new log...a little incentive perhaps to whip myself back into shape. Going with a 9'6" traditional singlefin noserider (using a Takayama NR2 template with some slight modifications to the tail width.) Picked out my blank and fin (9.5" Fins Unlimited Malibu Classic) last week, so she should be ready in a few weeks...I'm so stoked!!!
Thanks for reading and looking forward to any and all input...Lisa
