What are the key factors that make cycling a more effective form of cardio for weight loss compared to other activities like running, swimming, or high-intensity interval training (HIIT), and are there any specific cycling techniques or workouts that can be tailored to maximize caloric burn and fat loss? Additionally, how does cyclings low-impact nature impact its effectiveness for weight loss, particularly when compared to high-impact activities like running or jumping? Are there any studies or research that demonstrate the optimal intensity, duration, and frequency of cycling workouts for achieving significant weight loss, and what role do factors like diet, sleep, and overall lifestyle play in supporting cycling-based weight loss efforts?
