I'm a 13-year-old boy and I want to be fit so bad.

I have started by doing daily warm-ups (which I forget) and eating right (although rarely gets tempted to eat the fast/junk foods). I'm also trying to run but at the moment I'm pretty low in distance , maybe around 300m-500m if I jog but walking is a breeze so I guess I have to start that. I also get strength by doing push-ups but still I could only do 3-5 streak lol!

Here is my goals to fitness atm:
*Eat entirely healthy (no fast/junk/friend/highsugar/highsalt foods)
*Jog/walk alternately 1 km every morning
*Do daily warm-ups and stretching
*Less screen time (0-1 hr every day)
*Do dancing
*Increase push-up count

Why I'm doing this?
*For a healthier body
*Higher energy
*To be physically fit

Although I don't know what I'm going to post next , oh oh... well let's focus on the present. Anyway , I'm going to jog and stretch! Adios !
