So name's Alex, and for the past couple of months I have been going on daily walks over at the local park. I go every morning before the start of the day. Now, just to give you guys an idea of what that entails, I have to walk up a steep hill from house up to the park. This leaves me pretty winded to begin with, but then I also walk a full lap around the entire place once I get there. Now, the park is huge. The biggest in city. It has a massive baseball field (which is really just a field and a freakishly wide expanse of grass), a soccer field, a picnic area, play areas, a small basketball court, two parking lots, a tennis court, etc, etc, so on and so forth.
Anyway, there is a trail that loops around the outermost portions of the park, and that is the trail I take every day. I don't even skip weekends.
I don't post this to toot own horn, far from it. It's not a big accomplishment, and I just wanted to give you guys an idea of workout routine. But I know it's not enough.
I want to start adding running to the mix. I've heard of interval training, and I wonder if that is the best way to go. I recently saw a woman running with her dog, and she was doing exactly that: running around one side of the park, walking on the other side, running again, etc. It seemed like a really smart idea to me. But I'm no expert, obviously.
And I do wonder... are these workouts pointless considering how I spend the remainder of days eating, sitting around, etc? I do go grocery shopping a lot though, so I still keep active (kind of, not really), but I do have to wonder. And worry. Are morning workouts still the way to go?
I just want to lose weight. I don't care about building muscle or getting rock hard abs. I'm just tired of being fat. I'm not obese, but I am definitely fat, and I just want to be skinnier and more fit for once. Is running every morning, with or without the interval training, enough to achieve this goal? Or do I need to do more? And how exactly does interval training work? Do I just run as fast as I can, then take a break by walking, then rinse and repeat? Or is it more of a jog?
Gah, so many questions

Finally, and I almost forgot to mention this, but eating right has never been a problem for me. I don't even drink soda or eat candy (I just don't care for either that much... lucky me, I guess?), and breakfast usually consists of a granola bar and milk, lunch consists of a sandwich and chips, and dinner consists of meat, rice (I'm Chinese), and vegetables. I could go into more detail if you guys want, but once again, I just want to give you guys an idea just in case. I've never had to post something like this before on a forum, haha.
