There are no serious consequences. It is ok to have a rest for two days. The rest time of fitness muscle groups (for exercise muscles) is generally 24 -72 hours. If you don't rest for 24 hours, your muscles will not return to their best state and you will feel tired. If you exercise a certain muscle group for more than 72 hours, don't focus on exercising this muscle group the next day. For example, if you exercise the biceps brachii, triceps brachii and pectoral muscles of your arm today, you will feel tired the next day. On the third day, exercise biceps brachii, triceps brachii and pectoral muscles (for example). Take a day or two off every week. Rest is not recommended, take a rest. You can relax by playing badminton, volleyball, running, walking and yoga.
