• II. Muscle Endurance

• III. Muscle Strength

• IV. Flexibility

• V. Body Composition

*You should be exercising 60 minutes a day5 days a week

Cardiovascular Endurance

• A. Requires using the heart and lungs over a period of time.

• Check your RHR (Resting Heart Rate): Check your pulse for 6 seconds and multiply by 10.• What is a healthy RHR?• MHR; (Maximum Heart Rate) 220-age.• THR; (Target Heart Rate) 70-85% of MHR, this is

also known as the “Training Zone”. • Examples of activities that will get your heart

Reps.• Football• Mountain Biking

Muscle Endurance• Ability of a muscle to

work over a period of time.

• Low weight/High repetitions

• Sit-ups• Wall-sit• Long distance

Bicycling

• Total amount of bone, muscle, and fat in the body.• 2 weights: Total body fat percentage & lean

muscle tissue.• Ways to determine body composition:1. Underwater weighing2. Skin fold/caliper3. Body fat percentage machinesEveryone needs body fat for:• Insulation• Body temperature regulation• Storage for energyMen need at least 3% body fatWomen need at least 12% body fat• Activities that have an effect on body

composition?
