What do you think about exercise? For... against... not sayin'? Exercise is important...even more so in our day and age. With all of the fast food, easy fix boxed foods, and preservatives our children are ingesting more "fake" foods than ever. Couple that with all the computer use, video games, and cable tv... and we have a monster on our hands.
Our children need to be taught that exercise should be a part of their daily lives, whether they are homeschooling or not. They should see us doing it regularly, and they will emulate our example. Your middle school student needs a healthy amount of exercise each day, even if it is only a walk. The typical 8th graders muscles are growing rapidly, and thus needs to be stretched and worked. Not to mention the fact that at this age, habits are forming that will become part of their daily lives.
Get up and Get fit... make exercise a daily habit!
