For a beginner at-home workout, get down with push-ups! Do a set before you shower in the morning and another set when you get home from work. You can even do them during commercials while you watch TV!

For an easier version of this exercise, start from your knees. Make sure your back stays flat. You can do these for 20 seconds or until you get tired.

Adults need 30 minutes of physical activity every day. Kids need 60.
