In a full-body routine, you train every major muscle in your body, like your chest, back, arms, hamstrings, and abs, in each workout. They incorporate exercises that engage many of those muscle groups in one movement, like squats, deadlifts, and overhead presses, all of which are also called compound movements. Compound movements demand a lot of energy and burn more calories, but they also beat up your muscles and typically require you to rest more between each set of exercise and whole workouts.
The upside is that when you work out the same muscle groups by doing the same or similar exercises multiple times each week, you improve your overall body strength, rather than just in one area.
Circuit training, metabolic intervals, and compound lifts engage more muscle groups, skyrocket your heart rate, and burn more calories. Hitting your full body all the time from a conditioning aspect is great; its the model CrossFit follows.
