Exercise Facts
Only about 1/3 of adults regularly work out, says the Centers for Disease Control. Everyone should exercise at a moderate level for 2 1/2 hours per week, or 1/2 hour per day, five days per week. If you can talk while exercising but can't sing, you can consider the activity moderate. If you find it hard to speak more than a few words while exercising, you are most likely exercising at a vigorous level and only require 1 1/4 hours weekly, or 15 minutes daily.Read more: http://www.livestrong.com/article/330179-exercise-heart-disease-statistics/#ixzz1PGc55psj
