Keeping that extra weight off

Been trying to jog between 2-3 times a week.Last week I managed to jog 3 times cos I had that sudden motivation to wake up early.But the maximum I could go without stopping is only 4km.Im trying to train my stamina cos after all I have stopped exercising for a period of time.
And I super love the feeling after I'm done jogging.Even though it was really tiring,I feel healthier and won't crave so much of unhealthy food.Every single run gives me a sense of achievement.
But Im still waiting for my armband to arrive.I ordered it from qoo10(Prefer to say gmarket) and it would be so much more convenient for me.It's such a trouble to hold on to my phone when running.A hindrance too.
I couldnt wake up early in the morning so Im gonna jet off later in the evening.
