I know, it sounds too simple. But - here are some statistics:
Reduce your risk of breast cancer by 20%, heart disease by 30-40%, and diabetes and stroke by 50% just by walking 30-60 minutes a day.
But that's not all, you can also:
Raise your high-density lipoprotein (HDL) cholesterol (which is the good cholesterol)
Lower your low-density lipoprotein (LDL) cholesterol (which is the bad cholesterol)
Lower your blood pressure
Reduce symptoms of depression and anxiety
Maintain lean muscle
Increase cardiovascular endurance
Reduce the pain and joint swelling that accompanies arthritis
Increase weight loss and reduce body fat
That being said let's remember that this healthy lifestyle you have adopted does NOT have to be as difficult as we sometimes make it. During the next few weeks you will all be busy with family activities, social gatherings, crazy shopping lines and so many other things to push you off track. So rather than trying to find time to get out to a scheduled fitness event, why not put your boots/shoes on, ask a family member to watch the kids for 20-30 minutes or bundle them and bring them. I am sure that your guests would not mind visiting with the kids while you got your fitness in and you will feel much better after, ditch the guilt and gain the peace of mind that you did it!
