Yes, I know, I live far north where the sun sets early and comes up late, we also have harsh winters, so its a challenge.

But building muscles and stamina is critical for recovery and walking/workout is something almost everyone can do. Running is much much harder, it takes a heavier toll on the body and when starting out your more likely to get sick etc.

When you set the routine (takes a month), you will long for walk every day, everything seems to calm down allot during and after the walks.
