To be effective, fitness training should prepare the athlete for the demands that are placed on them in their chosen sport or activity. This means selecting the right types of training and following established training principles. This programme examines aerobic and strength (resistance) training and uses these types of training to help illustrate the following principles: - Specificity - Progressive overload (incorp. FITT) - Threshold - Warm-up/cool down - Reversibility - Variety - Assessment. Fitness training prepares the athlete, as they select the right type of training and follow established training principles.
