I. Cardiovascular Endurance II. Muscle Endurance III. Muscle Strength IV. Flexibility V. Body Composition *You should be exercising 60 minutes a day 5 days a week

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 into the “Training Zone”?

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 weighing 2. Skin fold/caliper 3. Body fat percentage machines Everyone needs body fat for: Insulation Body temperature regulation Storage for energy Men need at least 3% body fat Women need at least 12% body fat Activities that have an effect on body composition?
