Does exercising for 30 minutes 3x per week improve health outcomes?
For years we’ve been told that 30 minutes 3x per week was all we needed to do to improve overall health and body composition. However, according to most research, this minimal amount of activity does very little to improve either health or body composition. New government guidelines suggest that to improve health, one should shoot for 30 minutes of exercise every day. And to improve body composition 60-90 minutes a day is required. Now, before you go whining about time – North Americans plop down in front of the TV for an average of 19.8 hours per week. Surely we can make the time for 3.5-7 hours of exercise per week.
