Rothstein Quoted in Conditioning Story

April 23, 2024

Peloton’s blog, The Output, interviewed Alex Rothstein, M.S., instructor and coordinator for the Exercise Science, B.S. program, about metabolic conditioning (metcon) workouts. As he explains, the body relies on three metabolic systems—phosphagen, glycolytic, and oxidative—to store and make use of energy. Metcon workouts, which often utilize circuits of strength training, cardiovascular exercises, and high-intensity intervals, challenge all three of these pathways in one efficient workout. 

“Metabolic conditioning workouts often alternate different exercises or groups of exercises to work between high and moderate intensities and work the aerobic and anaerobic energy systems,” says Rothstein. “All three systems are always working but the percentages of energy that come from each vary depending on our body’s needs.”
