If you have 25 lbs. or less to lose, you can do it in two months. Any more weight than that is not healthy to lose in such a short amount of time. You will need to be willing to eat right and exercise on a daily basis. You will need to be fully committed, as some days you will find that you are tired and don't want to exercise. You must do it anyway.
Eat right and drink eight glasses of water per day. You can exercise all you want, but if you don't incorporate good eating habits it won't do you any good.
Create an hourlong exercise routine that you can do in the morning, five to six times a week. If you don't have time in the mornings then you will need to set your alarm clock for an hour earlier than you usually arise. You cannot lose weight without making some changes.
Begin with five minutes of stretching. Stretch your arms, legs and neck. This will get you ready for your cardio workout.
Do cardio for 30 minutes. You can use a workout tape or sign up for a class at the gym. You could also just go running for 30 minutes. Cardio is important for burning calories.
Spend 20 minutes doing strength training. Strength training will build up your muscles while toning up the areas that are losing weight.
Finish off with another five minutes of stretches. It is important to once again stretch your muscles so that you don't pull one when you go on with the rest of our day.
