This document provides an introduction to different types of fitness training methods. It discusses interval training, which involves bursts of high intensity exercise alternated with low intensity recovery periods. Tempo/continuous training builds stamina through moderate runs at a consistent pace. Circuit training combines strength, cardio and muscular endurance exercises in circuits with short rest periods. Weights training uses free weights or machines to progressively overload muscles to build strength. Plyometric training develops power through explosive movements like jumps and throws. All training should follow the F.I.T.T. principle of frequency, intensity, time and type of exercise.
