By building up to it. You don't run a marathon without first running a mile!
Start slow, and build up a little at a time. It takes time to build your endurance. Trying to do too much, too soon not only doesn't feel good, it can put you at a greater risk for injury.
Start out with 30 minutes, 3 times per week, and as that starts to get easier, start increasing your time.
Make sure you include some strength training in your program. If you neglect strength training, you'll be burning muscle as well as fat, so strength training is critical for the preservation of your lean muscle mass and for boosting your overall metabolism so you can burn more calories at rest!
