1. Make a plan: First of all, you need to make a fitness plan, including the number of days you want to exercise every week, the time you want to exercise every day, and the goals you want to achieve. This will help you stay motivated and track your progress.

2. Be consistent: Try to do some form of exercise every day, even if it's just walking or doing some simple stretching exercises. Consistency is the key, because regular exercise can help you build muscle memory and adapt your body to your exercise habits.

3. Think about your personal schedule: Think about your personal schedule and see which time periods are best for you to exercise. Some people may be more active in the morning, while others may be more active in the evening or afternoon. Choose the time that is most convenient for you.

4. Rest and recovery: Make sure you have enough rest time between exercises to give your body time to recover and repair. If you do high-intensity exercise for several days in a row, it may lead to excessive fatigue and injury.

5. diversify your exercise: trying different types of exercise can help you prevent boredom and help you get the most benefit from different muscle groups. This may include aerobic exercise, strength training, yoga or flexibility training.

6. Listen to your body's signals: If you feel tired or painful, don't force yourself to exercise. Your body needs rest and recovery, or you may get hurt. If you are not sure when to stop, you can consult a professional fitness instructor or doctor.
