 Total Core starts with a jerking motion,which causes strain on the neck,shouders and lower back.The Total Core eliminates this first jerking motion and than guides you through a smooth,full range motion that far exceeds the range of typical crunch while you are comfortably seated and properly supported.The secret behind the Total Core is the unique progressive resistance system that "pushes" you upward with more of a "push" in the beginning of the movement when you need it most and less toward the end. But there is more!The Total Core turns the crunch "upside down",because on the way down you pushing against the same unique progressive resistance which works your lower back and the back of the "core".
