Aerobic • • • • Long duration Uses large muscle groups Does not require more oxygen than can be taken in Examples include jogging, biking, rope jumping 2.

• • • • Anaerobic Short duration High intensity Requires more oxygen than can be taken in Examples include sprinting, weight lifting

Both are effective for managing stress and expending stress products

Intensity Frequency Duration

Assess fitness (e.g., take the Rockport Fitness Walking Test) Begin each session slowly and gradually

For Maximum Benefit:

 1. Intensity – Target Heart Rate  _____ 220 – age = maximum heart rate  Beginners – work out at 60% of maximum  Advanced in good shape – work out at 80% of maximum  Can you carry on a conversation while exercising….

For Maximum Benefit:

 2. Frequency  At least every 48 hours (3-5 days a week)  3. Duration  20 – 30 minutes minimum (depends upon level and intensity)

Types of Training

 START ANY NEW PROGRAM SLOWLY!!!!

 Interval training- changing intensity for short time  Continuous training-steady 60-80% for duration  Circuit training- aerobic and weight training  Competition vs. enjoyment
