Most people are doing cardio… but not doing it effectively. 🤷‍♂️ Intensity and …more

original sound — @kailiefitness

what it claims

To burn more with cardio, raise the incline and resistance rather than just the speed — a steep, effortful walk taxes more energy than an easy jog.

Adding incline or load to a walk measurably raises energy expenditure at a matched pace — well documented in lab studies, the same principle behind weighted rucking.

Adding incline or load to a walk measurably raises energy expenditure at a matched pace — well documented in lab studies, the same principle behind weighted rucking. Incline walking also recruits the lower body more than flat walking, supporting the core point. Where it slips: calling most people's cardio 'ineffective' or 'a waste of time' overreaches — flat walking, even at modest doses, is linked in large device-based cohorts to lower mortality. The mechanism (intensity and resistance raise energy cost) holds; the definitive tone about what 'doesn't work' is oversold.

Other advice in the Register that leans on the same research.

To significantly increase endurance and strength without gaining muscle mass, practice a one-mile (1.6 km) walk/jog once a week while carrying a kettlebell weighing 30% of your body weight, switching arms regularly.

Adding weight to your backpack (weighted walking) allows you to optimize the efficiency and intensity of your walking session.
