I still insist on doing exercise every day. For a weak person, it is not advisable to start with difficult items, such as push-ups, but you can choose your favorite, lighter exercises, such as jogging, walking, kicking, jumping rope, sit-ups, balls, etc. in the first place. Pay attention to keep a certain amount of time, not less than half an hour a day. For soothing exercise, you can extend the exercise time to sweat is better. Second, you insist, often insist, it is best not to interrupt. It is difficult to do this. You must be conscious and have perseverance. If you are interested in these exercises, you will stick to them. In addition, are gradually increasing the amount of exercise, consolidate the results, broaden the range and scope of movement, choose the right project for you, long-term practice. In addition, exercise should be targeted, for the weakness of the body, you need to choose the right type of exercise, such as weak, should do more aerobic exercise, such as jogging, gymnastics, taijiquan, yoga, etc..
