The Basics on Exercising for Weight Loss

The reason why many people fail in their weight loss goals is because they over-analyze what they are doing, get disheartened, then quit. Here I will let you know in simple terms what you need to do to succeed with a new exercise program.
Firstly, you just need to move. Walk around the house, up and down the stairs, to the shops, it all counts. If you move more now than what you did before then you are in front.
If you are unfit start with short walks. You would have read that you should exercise for at least 30 minutes per day but if that is too much for you, you are better off starting with 5 minutes, then building it up to 30 minutes. Alternatively, you can complete 3-4 * 5 minutes walks per day, which will bring you results faster. If you can sustain 30-60 minutes then try to change the course you walk/run each day of the week. This will at least change the scenery. Also, find a friend who is fitter than you to exercise with. They will provide motivation and be less likely to quit on you.
Now having a program will do little good if you aren't training regularly. Forget the excuses. If you really want the results, you will find a way:
Knee/ankle injury: swim
Have kids: take them with you or find a friend who also wants to exercise and look after each other's kids whilst the other exercises.
Don't have time: well find 30 minutes. I'm sure you could find the time to do something to save your life (and one day it may come to that)
Don't have energy: you will find that you will actually have more energy once you increase your fitness level
You will have days where you just don't want to exercise. We all have them. These are the days when you must train. If consistency is the key to success, then training on the days you don't feel like it is paramount, because you will have more of those than days you feel like it. The way accomplish this is to have shorter or less intense sessions on these days. Now of course you can't be having these types of sessions every day but if you can push through your un-motivated periods doing this then you will succeed.
So that is it. Find a form of exercise you enjoy, start at a sensible intensity, and do it consistently!
