When I started working out I didn't do a lot of cardio...?

Question

And now for the past 4 or 5 weeks or so I started doing cardio a lot. I've been running a lot but everytime I get so tired still like i'm not making any progress. I even sweat a lot more then I use to when I didn't do cardio much. Even sometimes just in the heat I sweat just standing there, I never use to be like this. Does anyone know why this is happening to me?

Answer 1

You sweat more as you get in better shape. Your body is just working to keep your muscles cool.
