Scheduled rest and recuperation time is vital for your workout program. As mentioned earlier, high intensity training can cause a need for longer recovery time. In fact, even moderate aerobic training or resistance training can create a need for more rest. Many people fall into overexercising due to good intentions but poor information. Many reason that if three training sessions per week are necessary for good fitness, then six must promote super fitness.
Rest builds up the body to a higher level of strength.
During the rest periods, your body also recovers the energy it lost during a workout and builds up some extra energy for future workouts. Without enough recovery time, you run the risk of overtraining. Overtraining is characterized by persistent soreness or stiffness, a rise in the resting heart rate, fatigue, lack of motivation, irritability or depression. If these symptoms are ignored, an injury will eventually force you to rest, and much longer time will be needed than if you were already scheduling recovery time. It is important to cooperate with your body's cycles of work and recovery.
