The most effective type of exercise for weight loss is a combination of cardiovascular training and strength training. Cardiovascular activities, such as running or cycling, create a caloric deficit essential for weight loss by burning calories. Meanwhile, strength training builds muscle, which increases resting metabolism, facilitating more calories burned at rest. High-Intensity Interval Training (HIIT) is particularly effective, as it incorporates bursts of intense activity followed by rest, maximizing calorie burn both during and after workouts. Ultimately, the most successful exercise for weight loss is the one that is adhered to consistently and tailored to an individual's preferences.
