It is very important to rest muscles between workouts. In fact, resistance training breaks down muscles causing microscopic tears. It is only during rest when the muscle-building process is stimulated and the regeneration of new tissue occurs. But when muscles are not allowed adequate rest and recover time, the regeneration process cannot occur. This can have several side effects such as increased soreness, decreased strength and performance, and may lead to injury. A general rule of thumb is to allow muscles 48 hours rest between strength training workouts.
Resting muscles between workouts is extremely important because exercise causes muscles to break down. You should allow 48 hours between workouts of each muscle set. This means you can work out one area, like the upper body, one day and another section, like the lower body, the next day. Bleeding and tearing at the microscopic level takes place after a good workout. It may take several days for the muscle to heal. If you work muscles especially hard, you should only work them once a week.
