your question is too broad. When designing a fitness program, there are a few factors that play into it:
– the results of the screening
– the goals of the client
– the environment in which the client wishes to train
Program designs are different for a marathon or short distance runner, for a person recovering from an injury and a budding athlete.
I’m with Karin on this one. Once you have these factors in place then you can create a personalized program for the client. Yes, there are guidelines to follow provided by various certifications and organizations, but at the end it all comes down to the 3 factors Karin mentioned. I hope this helps with answering your question.
