I'm definitely going to rewatch this video in the stability protocol. I tried it for the first time this morning. Once I got my arms to 90 degrees, it immediately exposed my injuries (golf and tennis elbow). I was shocked. I couldn't finish what was required to finish this particular stability exercise. My question has to do with weights and range of motion. I didn't use any weight because I did this exercise at home. I know you said in the video that you could do the weightless but I'm assuming adding load would be the goal. am I correct is saying that?, and the range of motion is weird to be honest, not the range itself but how it felt to me because this is obviously new to me. Am I trying to complete full range of when twisting the arms, or for lack of a better term, a condensed range of motion when twisting? I hope this makes sense to you my friend. I do have more questions.
