Running

Running destroys 600–800 calories per hour at a 10-minute mile pace for a 155-pound person, making it one of the highest-burning aerobic exercises. Its high impact drives bone density gains and requires zero equipment, beating #4 Swimming on cost and accessibility. A 2021 meta-analysis found running reduces visceral fat 15% faster than moderate cycling, highlighting its edge for visceral fat loss. For optimal weight loss, incorporate interval speedwork to amplify the afterburn effect.
