Health is the capital of revolution. If you are willing to keep fit, it is certainly a good thing. Doing this every day not only exercises your body, but also cultivates your perseverance. Of course, if you really want to review for the exam these days, you can stop, but you'd better not, because it will further develop your lazy habit and you will think about taking so much rest next time. If you don't persevere, it will be ineffective.
