In my experience, doing 3-6 reps is the sweet spot for this type of training. As this is done in a circuit fashion with incomplete rest, you'll be unable to perform the same loads as during traditional lifting sessions.
The water on your body changes to a gas called water vapor. Water turns into a gas through a process called evaporation. Heat makes water evaporate faster. All air has some water vapor. Tropical rain forests and deserts are both hot.
So, as the fast molecules escape, the temperature of remaining water drops. That's why evaporation cools. See Figure 2, top drawing. Water boils when evaporation occurs throughout the pot â not just on the surface â and forms bubbles that are buoyed to the top where they escape.
