For Individual or Group Training, learn how Physiological Capacity "Exercise Age" affects heart rate response and the appropriate choice of modifications made while paying close attention to specific heart rate ranges and training details that make safer and more efficient use of time spent training. This guide will educate you on the physiological adaptations that occur in a diverse training regimen and will help any individual to bridge the gap between science and practical application. The types of exercises covered are Strength, Balance, Coordination, Power, Speed, Agility, Cycling, Running, Rowing and High Intensity Interval Training (HIIT)
