You should definitely take it easy for a few months, you only have one ankle per leg and REALLY dont want to mess those up. Do some power/fast walking or swimming for the first few months. Then you should be able to start running and jumping as you would normally, just ask your doctor what he thinks.
You can still do weight training. Building lean muscle helps your metabolism stay higher and burn more even while resting. Maybe try squats as well if your able to do that in a boot.
Can u swim?? That's what I did after my foot surgery.
