It seems popular lately to spread the idea that we do not need steady state cardio (walking, jogging, swimming, etc.) in order to achieve fat loss. Many a Gym Bro insist we only need to lift weights—the heavier the better— to lose body fat, claiming excess post-exercise oxygen consumption (EPOC) will do the trick. But these Gym Bros wrongly apply the EPOC science. Remember: you never see an overfat marathoner; but you see plenty of overfat lifters. Anyway, read this short linked first-person account of a fat loss journey involving cardio exercise.
