What is the appropriate PROGRESSION?
How can the difficulty and intensity be increased or decreased?

Progression is taking a movement and using different methods of exercise technique to increase muscle and/or cardiorespiratory intensity to cause overload, which in turn increases the level of function and fitness. A quick example in land exercise would be to progress a jumping jack by adding higher jumps and forms of plyometric actions to increase intensity. In Aquatics you could progress a jack by scooping more water with the hands and raising the knees on the in and out to increase intensity.

With a little thought virtually all movements can be safely progressed to increase the intensity of a class or training. In addition, progression adds variety through your teaching techniques and exercise choices.
