1. In the exercise where my feet are on the wall and I'm rolling my knees in and out, the muscles on the outside of ankles/calves started to fatigue. Is that supposed to happen?

2. How can I tell if I'm rolling my sacrum forward but not arching my lower back? What should I feel?

3. In the last set of shoulder exercises at the end of the workout, how do I know what height to set the blocks? Also, during the setup, you said to roll the feet and legs out so toes touch but then in the middle you said to roll the legs in. Which should it be? Finally, the top of my forearms started to burn like the muscle was fatiguing. What can I do to correct this? It was really uncomfortable so I think I was doing something wrong.

Thank you!

1) if the outside of your ankles and calves have not been working the yes, this would activate those muscles and they would fatigue.

2) place your hands on your waist area to navigate whether most of the motion is coming from the pelvis or the waist.

3) Blocks do not need to be exact, but you could emulate the height of the back or your ribs as a target height, so you are aligning the harms with the trunk - it really will be dependant on how tight or loose your shoulders are so you may want to play with this. the burning in the forearms may be caused from tight shoulders - I don't know.   it is also normal as you are again using mostly unused muscles.

Hope this helps
