Hellooos..

I'm 21 years old and about a year ago, I was 75kg. I went overseas and i naturally lost about 12 kgs through cycling and good dieting. I've been back for 4 months now and my weight has more or less mantained as it is. However, I've got this problem with my weight coz it's constantly yoyo-ing. Meaning it fluctuates. I measure like every 2 weeks or so and sometimes I can be 65kg in this week and be like 62kg in the other.

I haven't done any exercise since I came back from overseas until the past month where I picked up jogging. Now I go about 6 days a week for about an hour or so around.. I'm guessing 8km/h? I'm not really sure. And through the past month, nothing much has changed. Weight as i've said, fluctuates. Inches hasn't changed much. Maybe as much as 1/2 an inch only?

The main reason I go jogging is because I made a promise to my dog to bring him out more often than I did before. So I'd hope that if anyone has suggestions to what I should do, could include the activities which I can do it with my dog. >.<
