The training threshold is defined as the minimum amount of exercise that must be completed to help improve the physical fitness of a person. The exercise is not considered to be an effective one when the minimum training threshold is not achieved.
Many people may choose to work out, but these people may not be hitting their goal of a training threshold. They are generally not able to achieve any type of improvement on their physical fitness when they only work out for short periods of time. The training threshold for people is different depending on their gender, their body type and the amount of fitness they have had in the past. For example, the training threshold for a 300-pound woman who has not worked out in 15 years will be much lower than the training threshold of a 150-pound man who religiously runs 5K races and goes to the gym on a daily basis. Finding the training threshold is an important aspect for many new athletes and for trainers of these athletes. It must be a safe level that will not cause the person to work too hard and damage their body, but it must be able to provide the person with the aerobic activity that is needed to improve physical fitness.
