There are so many options all around. If you can't walk outside try walking in a mall. If you have a gym can you take classes? Maybe yoga, aerobics, tai chi? There are so many options available. I used to be similar to you and now I can't wait to try new activities. I barely have enough time right now to go out hiking and I am already thinking "hey, maybe I should get roller blades or tennis rackets... or... or... or..." I am always on the look out for people outside doing active things and thinking... will I like that?
I have even considered taking up golf... weird... I never liked it much. Also the more active you get the more you will start looking for new ways to be active. On occasion I am lucky enough to head out of work early on Fridays (when all my work is done) and when I do this I head downtown to the waterfront and spend an extra hour or two walking along the boardwalk.
Oppurtunities are all around you (especially in the summer). Just stop and take a look. I got a great work out this weekend going to the zoo and walking around. :-)
I love taking a nice walk in the park or around my neighborhood. My husband and I have also started playing tennis at the park and badminton in the back yard. There's so many options!
If it's too hot to go outside, I recommend using free weights inside and do lunges, squats, bicep curls, etc. You can also do jumping jacks, push-ups, crunches, etc. I LOVE doing workout DVDs as well. You can find some pretty cheap and they are really enjoyable! I really like Tae Bo and anything that requires dancing. You don't even feel like you're exercising! Let us know what you find to do! ~Sara :o)
