Pilates Principle: Control

There is a reason why Mr. Pilates called his method "Contrology".  If you lean to control everything during your session (the breath, mind and body) you will have a beautiful workout.  This means that no matter the tempo (slow when first learning or quicker as you progress) there should be precise movements done in a deliberate manner.  Remember the control starts with your abs and then moves to your limbs.  The stronger your center the more you will be able to make each exercise look effortless.

Also make sure you are working toward your fitness goals by showing up to class early and mentally being present during each session.  Having this discipline will get you the results you deserve.
