In this short fitness advice video, the speaker contrasts cardio and weight training for fat loss. He explains that cardio burns calories only while you are exercising, likening it to a light switch that turns off when the activity ends. In contrast, lifting weights builds metabolically active muscle tissue, which requires more calories to maintain even at rest, thereby increasing daily calorie expenditure. He concludes by recommending that viewers incorporate three to four sessions of heavy weightlifting each week to build muscle and enhance fat loss, rather than relying solely on cardio.
