The HealthMax Pro has six adjustable hydraulic resistance cylinders.  The bench and leg press cylinders are mounted to offer adjustable positive resistance in both directions of your exercise stroke.  The butterfly cylinders provide the standard one way resitance. 

As you progress and become familiar with the Basic 10 Exercises you will become accustomed to the muscles that are being used for these exercises.  You can then begin to turn up the return resistance on the main vertical cylinder set or the leg cylinder set to exercise a different set of muscle groups in the same exercise cycle but on the return stroke as well.  This will result in a more efficient and challenging exercise.  Several of the Basic 10 exercises will be combined and reduced to just 6 basic exercises but with positive resistance in both directions.  Choose another 4 exercises to replace those 4 exercises that were combined and continue with a more advanced workout session.
