I have experienced Essentrics to be a holistically designed workout that thoughtfully considers the whole body. It's gentle on the joints, increases flexibility while intensely toning and increases muscle strength. It's a good, intelligently designed workout. I really enjoy it and feel like a million bucks! After one short hour with Dyan, once or twice a week, my body feels more limber and toned. My posture is definitely better, and best yet -- my jeans fit better!"

From a massage therapist's point of view I found Essentrics to be a great muscle slenderizing and strengthening workout that targets the whole body. This program was new to me when I started and I was pleasantly surprised at how great I felt afterward. I loved the constant motion of both arms and legs."
