If you're going to keep up working out even in cold weather.
I went for a run this morning. Did not regret it.
This is my only working advice for making it when it comes to winter workouts: Give yourself the liberty/permission to complain, sulk, bitch, moan, curse or even switch to walking once you've run a kilometer. Miraculously, I've never had to. Once the gear is on and that first kilometer is completed, you just keep going. You never regret a completed workout. Feel free to slap me for being this...way.
Below - a regular morning post the first km, once I've seen the light.
ps. why do cardio at all? Because it works.
