I have a threadmill that I am beginning to use. In the pass I would go to the mall to walk. I was wondering which is the best? For me with the threadmill I don't have to leave the house. With going to the mall I was able to meet people. I would like to what is best for my body.

both will get you the same results ... the only difference is that it is oftentimes easier to become injured on a treadmill because it's a machine ... make sure you have good supporting shoes, even for walking, and take time to get used to it ... meeting friends is always important ... maybe you can schedule a walking date with these friends, say, once a week or something ...

Both are just the two sides of the same coin but the main difference is the environment. What i pesonally suggest you is go ahead with walking soo that you can feel the fresh air with the cool breeze. Just think over it.
