Exercise is a very good thing, and may help recovery. But in any case, check with your dr. to see if any kind of activity is off limits until a certain level of recovery is reached, as doing the wrong thing surely leads to problems. I was also involved in athletics/track when I broke my leg and couldn't wait to start running again. I even found and was cleared for some exercise of my fractured leg while I still in a cast (sitting leg lifts, and that helped with quads).
The only cautions---1. Anything that causes sharp pain at or near the fracture needs to be stopped immediately. 2. Be careful of diet. Very, very careful. If you get involved in any strenuous training, you'll find others aches and pains may develop, as nutrients as rapidly depleted. I came down with ugly cramps for days, and that meant I had to adjust for certain vitamins, potassium....so be careful about diet.
A few things many people don't even think of can really help with a work-out-- For instance, if you can handle crutches, taking longer walks translates into an upper body work-out.
