Fat burning exercise - Day 3

Today is a rest day, Rest is physically necessary so that the muscles can repair, rebuild and strengthen.
Building recovery into any training program is important because this is the time that the body adapts to the stress of exercise and the real training effects takes place. Recovery also allows the body to replenish energy stores and repair damage tissues. Exercise or any other physical work causes changes in the body such as muscle tissue breakdown and the depletion of energy stores ( muscle glycogen) as well as fluid loss.
Recovery time allows these stores to be replenished and allows tissue repair to occur. Without sufficient time to repair and replenish, the body will continue to breakdown from intensive exercise. Symptoms of over training often occur from a lack of recover time. Sign of over training inludes a feeling of general malaise, staleness, depression, decreased sports performance and increased risk of injury, among others.
