I'm almost at the four-month mark post-concussion. I've been walking more and more, and am now doing short daily walks of 15 mins each (still going at a slow pace). Later this week I'm going to try for 20 mins per day. And so on. This has been a *very* gradual process for me. This is in addition to pottering around the house (doing some modest cooking, washing dishes, organizing, etc).

Early on, walking could be treacherous - at times it seemed to trigger (or at least contribute) to fairly substantial setbacks. I seem to be gradually tolerating more and more, and haven't had a major setback since mid-July (I've taken things slowly - excruciatingly so, at times - during the last month and a half). I still get symptomatic, and the symptoms can be constraining and unsettling, but they aren't nearly as severe or long-lasting as they were.

My goal is simply to keep building endurance and stamina. Once I can handle more walking, and go at a more normal pace, I would like to add other types of exercise, such as stationary cycling, gentle swimming, and very light forms of resistance training.

For what it's worth, my concussion specialist (who has an outstanding reputation) told me that running should probably be the last form of exercise to add to the mix. I said, you mean because it's jarring and could trigger symptoms? He said yes.
