Exercise MYTH #4: You must exercise continuously for 30 to 40 minutes to benefit your heart.

The TRUTH: Every bit of exercise adds to a heart benefit.

The enemy wants you to subscribe to the self-defeating All-or-Nothing Principle. The All-or-Nothing Principle: 'If I can't exercise continuously for 30 to 40 minutes, I'm not going to do it at all.'  We have been created to do what we CAN do. Research supports the fact that every bit of exercise accumulates to an overall health benefit. Conversely, every bit of sedentary lifestyle accumulates to damage your health and your heart.
