How to build up stamina?

I want to start running this summer and lots of bike riding but I need to build up my stamina and I don't know how. I'm a 16 yr old girl who only has a little space and time to practice.

Also I get sore really easy. so does anyone know a good way to stretch so that doesn't happen?

Running/jogging is the best workout for increasing stamina

Thus, you should start with slow and short distance

As time passes by you should start increasing your speed and the distance...



For example, you can run 1/2 mile in 1st week for 4mph for speed...

A week later, you can run 3/4 mile in 5mph for speed...



Just like this process, you should run depending on your ability...



If you are not used to running, start slow and short distance...

You should run/jog at least 20 minutes daily. It is better to do it at night before you go to sleep.



Remember, you dont have to sprint...
