If the thought of a gym membership or marathon training is too big a fitness goal, simply walking more will still bring benefits for health. One study found that walking at least four hours a week, or just 35 minutes a day, may reduce the severity of a stroke, and walking to work has been linked with a lower risk of cardiovascular disease and death, with an even lower risk for those who also walk in their leisure time. Picking up the pace can also bring extra benefits, with walking at an average pace linked to a 20% lower risk for all-cause mortality compared with walking at a slow pace, and walking at a brisk or fast pace reducing the risk even further, by 24%.
