Any time of the day you can devote to exercising is a good time for getting active,but if you want to make a healthy fitness plan, it may be helpful to keep several points in mind and find out the best time to exercise.

      First, try to know what kind of person you are. Especially, are you an early bird who always wakes up early in the morning, or a night owl(猫头鹰)who almost never goes to bed before midnight? Once you are generally aware of what your sleep characteristics are,you will understand better when your body needs exercise, either early in the morning,sometime during the day, or later on in the evening.

    Second, consider your daily plan. When do you seem to be most busy, and when do you plan your most important tasks? Try to fit in your exercise before or at least around these events if possible, so that you can keep exercising and your life won't be affected(影响)as well.

      Third, think about when you feel you have the most energy. For most people, that time is usually in the morning after a good night's rest, or after a long day of work. After a busy or much stressful day, exercising can reduce your working stress from hard work. 

       Lastly, find out the place you plan to do exercise. Your house provides exercise at any time if you own fitness equipment(设备)，but if there is a gym(健身房)down the street or along the way home from work, it will make it more suitable for you to exercise.

      More importantly, you need to make a plan and try sticking to it for one week. If you do so and can get through the exercise without being pulled in another direction, make it a habit. And once you have set up your fitness plan, don't make any great changes to it unless your doctor allows you to.
