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.
When water evaporates, the water vapor mixes with the air. Eventually the air has as much water vapor as it can hold. When this happens, no more water can evaporate from the clothes. Wet clothes dry faster on a windy day. This is because the wind blows the water vapor away.
