1. Improving Fitness Levels Mr. DiCicco

2. Exercise Metabolism  Aerobic: (cardio) low intensity physical activity that lasts a long duration  muscles have enough oxygen to produce all the energy they need  waste products: carbon dioxide and water.  these byproducts are easily expelled through the simple act of breathing.

3.  Anaerobic: high intensity physical activity that lasts less than 2 minutes  muscles do not have enough oxygen to create the energy you are demanding from them  Byproduct: lactic acid  Lactic Threshold: Too much lactic acid will make you slow down  Pain, weakness, aching in muscles  Uncontrollable breathing

6. Improving Cardiorespiratory Fitness  A combination of aerobic and anaerobic exercises are key to improving one’s cardiorespiratory endurance  Aerobic Adaptations:  Stronger heart  More blood  More mitochondria  Anaerobic Adaptations:  Increasing lactic threshold

7. Improving Muscular Strength and Endurance  Mostly achieved via anaerobic exercises  More muscles work, stronger they become  Achieved through resistance/ strength training  Free weights  Exercise machines  Own body weight

8. Improving Flexibility  Stretching is the primary way to improve flexibility  Yoga  Pilates
