Calories: The Original Renewable Energy

The key to any workout regimen is burning calories. Discover how that happens with Groupon's exploration of the body's inner furnace.

In all of weight loss, there may be no concept less aptly named than the calorie. That's because a calorie is a unit of scientific measure—specifically, a measure of the energy needed to raise the temperature of 1 gram of water by 1 degree Celsius. Though the calorie unit we associate with food actually refers to kilo calories—meaning when we say, “2,000 calories a day,” we actually mean 2,000,000. And if the number of calories we ingest is bad news, the upside is that we are burning them all the time.

A certain amount of calories—about 60–75 percent of the calories you burn each day—are needed to sustain the body's unconscious functions, such as breathing and circulation. Known as basal metabolic rate, the specific percentage depends on factors such as size and body composition, gender, and age (typically, as people get older, fat makes up a larger portion of body weight, causing calories to burn more slowly). Digestion makes up about another 10 percent of the calories burned, leaving physical activity to account for the rest.

During exercise, the muscles contract, causing the body's adenosine triphosphate (ATP) molecules to break down as the heart continues to pump faster and faster—increasing the body’s demand for more energy. Once the muscles have depleted the day’s caloric intake, they turn to other calorie sources to fuel the fire—making weight loss possible as the body begins to sacrifice fat cells to the god of the treadmill.

KO Studio

Coach Henry Castro believes the key to staying in shape is simplicity, not flash-in-the-pan fads. At KO Studio, Castro and his team dedicate themselves to helping clients reach their fitness goals the old-fashioned way. In 30-minute KO Box-Fit classes limited to six students, exercisers practice a challenging, fast-paced blend of techniques, which constantly change to catch muscles off guard like throwing a surprise party for your triceps. More advanced courses up the intensity, and include a 10-week kickboxing and boxing program specifically designed for women.
