Excessive training is the one in which the amount, the intensity or both are increased too quickly without proper progression. Training too often or with too high an intensity level doesn’t help to improve conditioning or performance and can lead to chronic fatigue or overtraining. If you try to train too often (such as daily), the muscles can become chronically depleted of their energy. If you are constantly in the catabolic state of metabolism (the breaking down phase) through repeated training, your body can’t make any progress towards remodeling, repairing and conditioning. Therefore you have to make sure that your program is periodized and slowly progressive.
