Lesson 7 Exercising Caution

Page 35: PHYSICAL FITNESS WHY SHOULD I CARE ABOUT PHYSICAL FITNESS?

Warm-Up and Cool-Down

• Cooling Down A cool-down helps your body return to normal after exercise. It helps the heart return to its resting rate.

Page 36: PHYSICAL FITNESS WHY SHOULD I CARE ABOUT PHYSICAL FITNESS?

Stretch

• How to Properly Stretch Stretch after a warm-up or cool-down. Stretch slowly, without bouncing. Stretches should be held about 10 to 30 seconds.

Don’t Go Too Fast

Page 38: PHYSICAL FITNESS WHY SHOULD I CARE ABOUT PHYSICAL FITNESS?

Improve Your Form

• Learning the Correct Form You should talk to your teacher or coach before trying a new exercise. He or she can show you the correct form and help you learn it.

Page 39: PHYSICAL FITNESS WHY SHOULD I CARE ABOUT PHYSICAL FITNESS?

Page 41: PHYSICAL FITNESS WHY SHOULD I CARE ABOUT PHYSICAL FITNESS?

Use Your Safety Equipment
