Enjoying Exercise Rest, and Sleep

Exercise is fun, it can be work or play. Exercise makes our muscles strong. We could not move without muscles. The stronger our muscles are, the better we can work and play.

Remember that food only builds muscles. Food plus exercise builds strong muscles. When we exercise outside, we also get fresh air and sunshine. Sunshine kills some germs. Sunshine hepls our skin to make vitamin D. This vitamin helps us to grow and to stay healthy. But, we can not exercise all the time. we need to take time to rest, too. The harder we exercise, the more rest we need. We need to sleep about 10-12 hours each night. When we are a tiny baby, we needs the most sleep.
