The human body always wants homeostasis‚ a balance within the body‚ and when it is not the body will take actions to place it back into homeostasis. Many people do not understand the benefits of a training plan‚ setting realistic goals‚ and sticking to the plan they create. This lack of understanding results in people not creating a training

1. Introduction ? What Product Life Cycle is about The Product Life Cycle (PLC) is a theoretical concept‚ which put forward that any product idea will go through different stages from beginning to the end. PLC is typically divided into 4 stages and could be illustrated by a bell-shaped curve (see figure 1). The stages are‚ namely: · Introduction · Growth · Maturity · Decline Total sales of the product vary in each of the 4 stages. They move from zero in the introduction stage to high at maturity
