A group instructor can do just one assessment in any single class. For example, you can do a step test at the beginning of the cardiovascular workout, with an extended warm up effect as a bonus. I like to casually discuss the results during the cool-down. I usually teach group classes at the same time slot five days a week. I choose one sport per week and use some of the basic movements, conditioning exercises, and drills in the session.
Men seem to like the format.
I often ask the members which sports they are interest them. Personal trainers with clients in sports training must have a thorough of knowledge about the movement needs. This is serious training. If the client is in serious competition you will want to establish good communication with the client's coach. If you find that you really enjoy this type of training you can consider expanding your skills and help local athletic teams.
