To stay fit, you need to exercise regularly. No matter what kind of exercise you do, as long you do it consistently. Consistency and consistency are the keys to success. You must be consistent if you are to see results.
Begin with a small amount of daily exercise (like walking). Increase the time you spend exercising each day until you can do 30 minutes. This could be running, biking, swimming or weight training.
Try to make sure you exercise on all days of the week. Don't skip any sessions unless you have a valid reason for not attending.
Wear appropriate clothing and footwear when exercising outdoors. It is important to take into account the weather conditions, and how they may affect your ability to exercise safely.
When you exercise, make sure you are drinking plenty of water. Avoid drinking alcohol during this time because it can cause dehydration. Also, don't drink caffeine-rich beverages like tea, coffee, or cola. They can give you energy, but will also dehydrate.
After your first exercise, you may feel tired. Keep going with your workouts and you'll soon feel more energized.
