Hi Cathe, you often suggest modifications in many of your workouts for various exercises, or even have a cast member performing the modification - sometimes you point it out, other times the castmember is quietly doing it in the background. Please consider having a dedicated cast member in STS 2.0 to demonstrate a modification for those of us with joint issues who want to still be able to use your incredible workouts. They could be in a slightly different outfit, or in the back. To clarify, I don't mean a modification for total beginners, but one to keep the excercise safe for everyone. Thanks!
