While I’m not a doctor, I have (unfortunately) a lot of experience coming off injuries and I have learned the hard way that its best to not try to plan too far out. Rather, plan a week of activity at a time and judge how you feel after each work out to decide if you complete the next day’s workout or if you rest. Then, if you completed the whole week’s workout, do a small increase for the next week.
You will come back stronger and faster if you take it slow and cautious rather than deciding a priori on a plan for returning to your prior fitness levels.
