When I was a coder I was riding my cheap bike to move in the city everyday in Montréal (even by -35°C). And bike is very good for cardio which is a main way of staying in shape. I was taking 30 min to skate from time to time in winter near jobs, and running in summer on the mont royal.
Thanks to this I have free gym 12hr/day in my new work as a mover that I got by looking in shape.
Your body is as much an asset as your mind. Invest in it because else you will have debilitating pain sitting on your chair when you will be ~40 yo.
