When you’ve done these homework, you’ll see that you can start with the running and walking intervals. If you are in good physical shape, you can start with the combination of both (running and jogging). You should notice what your body needs.
Well, you have the option to start by counting the time (run 3 min., walk 2 min.) or the meters (run 500m, walk 400m). I personally recommend that you start counting the time that the activity lasts, as I say a little higher, do not pay attention to the meters or kilometers you do. You gotta remember, running doesn’t mean rushing.
Leave all electronic gadgets at home! It’s true that we all like to wear the watch or the app and see how you beat yourself, but for your first sessions I don’t recommend it since it’s the only way to focus on what really matters.
