- For Week 2

-- Personal Sleep Goal
Dedicate 8 hours each night for the next week, just for sleep.

Now that you have an idea of your sleep habits, did you get 7-8 hours of restful sleep each night?

Common barriers for achieving healthy sleep include the following:
•Variable bedtime and wake time;
•Inability to fall or stay asleep;
•Work or family responsibilities;
•Busy schedules of social, work and family life;
•Poor sleep environments with light, loudness and electronics; and
•Caffeine or nicotine use close to bedtime.

-- Personal Activity Goal
How did you do? Take a look at the activity you wrote down from last week. How can you increase your daily physical activity? What do you want to achieve by the end of this challenge?

-- Personal Nutrition Goal
Take a look at what you ate last week. Did you make half your plate fruits and vegetables? Did you choose whole grains? Did you include dairy at most meals?

The Performance Triad challenges adults to enhance their health. Sleep, activity and nutrition are vital components to healthy living. (Editor's note: Information was pulled from the Performance Triad 26-Week Challenge.)

To measure your waist circumference, use a tape measure. Start at the top of the hipbone, and then bring it all the way around, level with your navel (belly-button).

Make sure the tape measure is not too tight and that it is parallel with the floor. Don't hold your breath while measuring.
