Any level of exercise reduces coronary heart disease risk, but the more the better according to the latest research. Walking briskly for 150 min/week cuts your risk by 14%. That's only 20+ minutes a day! Boost that up to 300 min/week or 45 min/day and you'll reduce your risk by 20%.
PositiveTip: Take a brisk walk today, no matter how short or long...and make it a daily habit.
