How to exercise for the best results

In today's solo podcast I get into the vast topic of exercise. With so many different approaches, is it really possible to claim one way is the 'best'? And what 'results' are we looking for anyway?   We talk about the difference between activity, exercise and training, the WHO recommendations and what they really mean, the FITTA principles of exercise, the 5 components of physical exercise, the strength / endurance continuum, and why some people are 'low-responders' to exercise.
