Hi Mariela! This circuit style Boot Camp workout is a total body conditioning workout which I've designed to increase your overall stamina. Its about 60 minutes in length and consists of a warm up, 8 fitness cycles, and a stretch. Each cycle has four fitness components which will always repeat in order (but never repeat the exercise). The four components are cardio, lower body, upper body, and core and each component lasts one TOUGH minute. You will have a brief recovery after each component to recharge your body and switch your equipment(when required). The exercises are basic but the output is INTENSE. It may take a few attempts to find that perfect weight, intensity, and technique, but once you find it get ready to take on this workout with the eye of the tiger ;-)! Now is also a good time to mention that this workout is called Boot Camp strictly for its intensity and quick changes as opposed to relating to an actual military type workout.
