It depends what results you are looking for. I suspect 3 weeks ago you couldn't do week 3 day 2 so there's some big results. If you are looking for weight loss, it's 90% diet. Running helps a bit but you can't outrun your fork. Eating a proper diet will lose the weight. Running will make you better at running. The two together make you a goal achieving winner!!
But as for results, you had some successful results the day you stepped out the door, started the app and began to level up your life!
