Good news! New research shows workout effectiveness is not about how long you exercise, but how hard the workout is. The Danish study found that those who exercised to the point of perspiration reduced their risk of developing metabolic syndrome by 35 to 50 percent. On the other hand, those who walked for an hour each day experienced no reduction in risk of MS, which includes high blood pressure, glucose levels, and large waistlines.
Even better news: We’ve featured tons of workouts that take 20 minutes or less to get you the intense workout you need in the short time you have. Take your pick!
