Aww, you can do this. I'd start by:

a) setting down goals - small manageable pieces
b) weigh in each week with us http://www.dailystrength.org/c/Diets_Weight_Maintenance/forum/16363172-weekly-weighin-may-5-11
c) start with the exercises you love. I've lost plenty without a gym.
d) do some dance for as long at a time as you can stand it? 20-30 minutes at a time? There are so many options. SO, narrow it down into what you like doing.

No matter what you choose, just get started. on the diet, cut all refined sugars and flours, and sodas, drink plenty of water and do cut all the processed foods, especially anything with corn syrup.

You really CAN do this. You can really be at your best at your age and should be. :) One pound at a time. Just stick to your goals and know you may fluctuate from time to time and it's ok.

It's definately worth investing in an Xbox Kinect or Wii game like Dance Central 3 or Just Dance 4!! I've also heard that simply playing some music and wiggling around whilst doing household chores works effectively too! Washing the car, going for a walk, etc :)

Good luck!!

Is there any kind of free fitness options near where you live? Any public parks or college campuses with parcourses, where you go from one station to the next and do some exercise outside? You can also borrow exercise books and videos for free from the public library. I'm hoping some folks will jump in and give you some recommendations for specific online resources.

What about swapping? Is there something you could swap in exchange for working with a personal trainer? Like maybe babysitting or something?

Where exercise is concerned, my best advice is to do what you enjoy. You'll be more likely to stick with it if you do something that is fun for you.

Try not to get overwhelmed by numbers or length of time - Lori is exactly right - set some small, manageable goals, work on them, achieve them, and then set some new ones. That will help keep things moving along.

I agree with Beesley, if you don't enjoy it you won't stick with it for very long. There are so many different ways to exercise and many of them don't cost a thing. I love to swim and hike. I do have to pay an annual fee to the pool ($80 a year) but I also love to hike and live by a ton of trails, this only cost me a pair of shoes. Look online to see what options are in your area. The problem I've found with gyms is that once you pay the fees you may still have to pay for the individual classes. My aunt is on a fixed income and she was able to find an affordable water aerobics class at the local YMCA.

The whole process CAN be overwhelming, but I think the key is to start by setting small and reasonable goals. Example: Lose 5 pounds this month, or in 6 weeks, or whatever. Don't be too hard on yourself if you don't happen to hit your goal in the amount of time you set.
Workouts don't always require money! Grab your headphones and go for a walk. Walking is great exercise, as is swimming..also widely accessible, especially as the warmer months roll around.
This is a great group for learning and for support. Hope you find lots of both! Good luck!
