New.. and I feel lost

You could try walking every day and progressively adding 5 to 10 min each week. If 30 minutes feels too much to start off with try 15 to 20 and progress from there.

The idea is that you start no matter how little but that you start and keep going.

Have you got some friends you could set up walking dates with? I highly recommend that as a place to begin.

I find controlling my eating is the hardest part so good on ya for concurring that!

For exercise I'd say start small and try to find something that is fun. if you enjoy it you're more likely to keep it up. I LOVE playing kinect games- dance, sports, whatever, its all fun to me. I also have the Turbo Jam dvds and really enjoy that kind of exercise. And yoga, makes me feel soo good after (I have hip/back problems and it helps so much!) Do you have the treadmill or bike close to your tv? maybe try doing them during a half hour episode of your favorite show. Just start small and don't get discouraged, if you don't enjoy something try something else.

Hey, I'm Fiona
I believe that good eating won't do anything without good exercise as well. I would say to use the machines you have at home, at least 30 min each per day , 3 times per week and see if anything changes. If not, you can add other exercise routines in between. There are so many on Youtube. I'm currently doing Hip Hop Abs, P90x ( Only When I feel good about my self ) , and three other workout videos that I found on Youtube which work pretty well. I do these everyday. I know that the videos on youtube work well since they cause my whole body to be sore the next day ! When I eat, I keep in mind of approximately how many calories I am taking in, Then when its time to exercise, I try to burn 600+ over the amount of calories that I ate. That is called the daily Deficit. When you burn way more calories than what you take in, you will start to lose weight. Please give your self enough time to loose the 100 lbs, if you do it too quickly many things can go wrong with your body okay? If you exercise daily, the amount of calories that you burn will increase. Since I'm sore from yesterday, When i exercise later on today, my body will have to use more energy so that i can do the exercises which will help me to burn more calories. Did any of what I said make sense? lol. Anyhow, Fruits and Veggies <--- They should definitely become your bestfriends. They provide so many nutrients and less calories than any other foods. They contain great sources of energy which will have you up and going, ready to exercise. When exercising, and you feel the need to give up, just think about why you're doing it, what your reward is going to be, and how happy you will become.

Hi Renee, have you readed New Rules Of Lifting For Woman? Its a great book and it could guide you.
Try something simple, like walking. Or running. But remember to take it slowly-you dont want to hurt yourself. Or maybe 30 Day Shred by Jillian Michaels.
There is tons of fun things you can do, have it

If you're not used to exercising at all, take the advice to start walking. Here are some tips and plans:

Walking is great exercise for beginners; it's not too hard on the joints and you can vary the intensity. You can do it on the treadmill, but unless you really don't have anywhere to walk outside, I recommend getting out, because it's a lot less boring.

If you can walk for an hour or two and want to kick things up a notch, you could try running. The Couch to 5K program has been successful for many, many beginning runners:

Since you have an exercise bike, cycling is also good, though it will take your butt a couple weeks to get used to the saddle (and most exercise bikes have saddles that are far too wide). It's low impact, and after you get your fitness to the level where you can cycle indoors for 30-60 minutes, you can have a lot more fun by cycling outside. (I cycle indoors during the winter, just to keep my fitness level up for long outdoor rides in the spring, but I don't enjoy it much.)

To get started: Position the saddle high enough up that your knees are almost but not quite straight when they are at the bottom of the pedal stroke, but your hips don't rock from side to side when you pedal (if they do, the saddle is too high). Set the resistance low enough so that you can do a full revolution of the cranks at least once every second (your cadence, the number of full revolutions you can make in a minute, should ideally be around 60-90: the idea is that each pedal stroke doesn't take much energy, but you're doing a lot of them).

Start off easy, with 10 minutes on the bike, then take a day off and try again. If you have DOMS - delayed onset muscle soreness - that sets in 12 to 30 hours after the exercise, don't worry; you can work through it and it will subside. (DOMS is characterized by soreness when you touch or exert the muscle, especially when you stretch it out or contract it fully; it tends to go away when you start working the muscle again. It's a symptom of the muscles repairing themselves from the last exercise bout. Acute pain that gets worse when you use the muscle, on the other hand, can be a sign of injury.)

After you're used to the bike, you can gradually increase the length and intensity of your efforts. Aim for an effort where you can talk but it's hard (not impossible) to speak in complete sentences.

I know there are a limited number of things that you can do due to your weight. My baby sis is in the same place. Look on YouTube. They have a TON of exercise videos to choose from and you can watch them before you decide to do them so you know if its the one for you. The elliptical seems to be the 'go to' one for my sister. But any type of low impact exercise to start is great. Weight lifting will be a good thing to look into also it will help you gain muscle to tone and keep your body fit . I hope this helps. Good Luck
